Math Updates with Mr. Math (a.k.a. Mr. Dubovich)

We are heading full steam into the home stretch!  We are in the middle of our last unit on Geometry.  We had a quick check over lesson #29 last week and now working through lesson #30 (2-dimensional shapes).  We are investigating quadrilaterals and triangles in this lesson.  The main purpose of the lesson is to review these shapes that they should have background knowledge on from 4th grade and work on classification.  They will be exposed to the word hierarchy and how it relates to comparing the shapes.  They will be responsible for knowing how to compare polygons, quadrilaterals, trapezoids, rhombi, parallelograms, squares, rectangles, and the six different types of triangles.

We will be quizzing over this lesson on Wed. of this week.  We will then due some further classifications in lesson #31 as we wrap the week up.  We will also be doing two mini in-class project with quadrilaterals and triangles.

NWEA is two weeks away!  Looking forward to seeing what growth the students have achieved this year.


Spring Break is around the bend!  We will use these 4 days before it to wrap up Unit #4 (Measurement).  We will spend the first 3 days reviewing our 4 lessons on conversions, line plots, the 3 “M’s” (mean, median, mode), and volume.   This should give students plenty of time to do review problems and ask questions to ensure they are prepared for it.  It will be worth 100 points.  Students will have a couple “review/study guides” to go over problems.  We will also review key vocab terms and formulas too.   The test will be worth 100 points.

Students will also receive their “volume quiz” back on Monday.

*There will be no stumper this week as I try to cut back on extra credit this 3rd trimester.


Volume! Volume! Volume! Learn all about it!  We started spending the end of last week and this upcoming week talking about how to calculate and understand volume.  There are 4 lessons in the book that we will be combining into one large lesson on this topic.  We will conclude the topic by talking about composite (irregular) figures this week.  This could be the part of the lesson that is tricky for some students since it involves calculating more than one shape.  We will wrap up with a quiz on Friday over all the lessons on volume.

We will spend next Mon.-Wed. reviewing the unit.  We will have a unit #4 test on the day before Spring Break on Thurs. March 30th.  It will cover lessons 21 to 27  and will be worth 100 points.


We are moving and grooving through Unit #4.  Last week we wrapped up line plots (Lesson #23A)  and moved on to mean, median, and mode (Lesson 23B).  The two lessons go hand-in-hand and the connection will be shown.  We did a quick check on line plots last week and most did well.  Those students that didn’t receive a good score made mistakes like not reading directions or double checking their line plots or how they read them.   Some of these line plots will show up again when we take our 3 “m’s” quiz this week.

We will be going over the relationship between line plots and the “3 M’s” on Monday.  We will do station work on Tuesday on the “3 M’s”.  Wednesday will be a Quiz over Mean, Median, and Mode along with line plot review.  We will start to get into the topic of volume on Thursday and Friday.   We will combine 4 lessons on volume into one major lesson over the course of the next couple weeks before spring break rolls around.

Also, keep in mind that students will be given a “45 minute” completion grade for i-Ready starting this past week.  Each week will be worth 5 points in the gradebook.  If they don’t meet this goal they won’t get the full 5 points.


Welcome to trimester #3!!  We are in the home stretch of this school year.  We finished off trimester #2 with a quick check on measurement conversion story problems (Lesson #22).  There were a decent amount of students who struggled on this topic.  We will continue to review and practice these during station work or small group instruction the remainder of the year.  The quick check grade was entered as the first grade of the trimester since I had absent students who needed to take it today.  Students always have an opportunity to better their results by doing stumpers on a weekly basis.

I decided to not do the volume lessons until the end of this unit.   This is the way they are laid out in the book.  We will be focusing on line plots and mean, median, and mode this week.  These are continuation of lessons that they received in 4th grade.  This is a great opportunity to start the last trimester off on a great note since the material is not overly complicated.   We will not be quizzing this week, but will have an assessment on both lessons sometime early next week.

Grades will be released on Wednesday this week for report cards.  Please check and see where your student finished for Trimester #2.


Welcome to the last week of trimester #2.  The year is flying by!  We will be wrapping up our lesson on measurement conversions (#21) this Monday with a quiz.  It will be the students last major grade for the trimester.  We will spend a day or so on story problems involving conversions before moving on to volume lessons.  There are 4 volumes on lesson and this will probably take about 6-8 days to get through all of them.  We will just combine these 4 into one MAJOR lesson on the topic.   Students will have abbreviated lessons on Tues.-Thurs. due to ISTEP this week.

During the 3rd trimester, students will be held accountable for their i-Ready minutes.  The goal is for students to get to 45 min. each week.  On a normal week, students are giving different opportunities during class to achieve this goal.


This week, we will start off with quiz/test over Unit #3.  This unit was very short (2 lessons) so it won’t be as long as a test, but will be worth more than a quiz in terms of point value (probably between 60 and 75).  The lessons are #19 (Expressions) and #20 (Patterns & Relationships).  We spent the last two weeks doing a plethora of problems on both topics and the students seem to be really grasping the concepts.  I’m really hoping this will results in some high scores on this quiz.

We will then be diving into Unit #4 that is titled Measurement and Data.  It has 8 lessons on a variety of topics.  We will start off with conversions.  It will involve using our customary measurements and also metric measurement conversions.  It will show the relationship between using division and multiplication in converting from one unit to the other.  Students will not be responsible for memorizing units, but will have to know how to use the measurements from one form to get to another form.

Also, in order to best prepare the students for ISTEP+ next week, we will be doing some lessons during our SRT time over material that could appear on it.  The students will NOT be assessed or graded over any material presented during this time.  Mrs. Alford, a wonderful former math teacher, will also be supporting me in her classroom in this prep time.  Students involved in Title I or RTI will remain in the classroom for this enrichment time this week.


We are done with fractions!!  I’m sure this will make most students (and maybe parents) very happy.  Overall, I was very impressed with the results of the unit test scores on this topic.  The students will be getting them back tomorrow and bringing them home.  This is a very important topic that will carry over into 6th grade and beyond.  If they are still struggling, you may want to provide some extra support, as I will on my end too.

We are moving on to a short unit on “Operations & Algebraic Thinking”.   This unit has only 2 lessons and we will get through them in about 2 wks.  The first lesson this week involves “expressions”.  We will look at how to write, model, and put into words different expressions.   An example of what we will be working on is seen in the Kahn Academy video link below: (except we won’t be dealing with negative #’s)

We will have a quick check on this topic at the end of the week.  Next week, we will spend time on patterns and relationships (Lesson 20).


We are getting towards the end of our fraction unit.  We will be working on some fraction story problems in lesson #16 this week.  It will still involve multiplying fractions, but we will also be looking at mixed #’s and improper fractions when multiplying.  We will spend 3 days working through various problems in our Instruction Book and Practice Book (homework).  We will quiz on Friday.

Students will be getting back their Lesson #14/15 quiz tomorrow.  Some really understood it, while others still are having trouble seeing multiplying fractions is finding a part of a part.

Lessons 17 & 18 will be combined into one large lesson next week.  We will combine them into one quiz.  After that, we will probably be testing in about 2 wks on the entire unit.

We will then head into our short unit on algebra. 

*Also, mid-terms are this week.  Please check to see how your child is doing in my class.


Welcome back and Happy New Year!  We are going to start off 2017 with where we left off in 2016, FRACTIONS!

For starters, students will be given back their quick checks from lesson #12 (fractions as division) on Tuesday.  Many students had trouble conceptualizing how to write a fraction in a given situation.  They will be given an opportunity to redo it as a take home assignment/requiz on Tuesday.  This concept is important in understanding the basic principles of what a fraction really represents.

We will then be diving head first into multiplying fractions.  This concept reintroduces students to what multiplication represents, “repeated addition”.  Lesson #13 will take about 4 days to get through.  It will involve dealing with multiplying fractions times whole numbers and fractions multiplied by fractions.

Fraction Time!!  We are headstrong into working on adding and subtracting fractions in this first lesson of Unit #2.  We spent last week going through a variety of problems adding/subtracting liked denominator fractions, unlike denominator fractions, and mixed number fractions.  This lesson really has a variety of parts.  We watched videos, worked in small groups/stations, and did a class fraction bingo on Friday.  Students have had various assignments in their practice book to assist in gaining confidence and knowledge on how to do these problems.

Lesson #2 is a continuation of #1 but includes the use of story problems in dealing with them.  We will spend the first couple days doing some of the problems of this lesson and then do a combined lesson #1 and #2 quiz on Wednesday.  We will also be taking our Winter Diagnostic Test for NWEA this week.  It will hopefully show the improvements students have made using our i-Ready math program this first half of this school year.  These results will be sent home once finalized.  The back of the week we will be getting into fractions as division.  This will carry us into the final week before break.

Also, posting some fraction resources on the math resource page.


Short week due to a well deserved Thanksgiving break.  Even though we only have 2 days, they’ll be busy with wrapping up this unit.  On Monday we’ll be reviewing for our upcoming Unit #1 Test.  Students worked on a study guide last week and we checked it in class on Friday.  We’ll be doing a Kahoot! tomorrow in class using our class laptops.

On Tuesday, we conclude the unit by testing over the nine lessons we’ve been rolling through the past couple months.  This test will be between 14-17 questions and worth 100 points.  Students have had 3 days of prep in order to rock the place value and decimal world!

Also, there will still be a stumper available this week.  It will be due on Monday, Nov. 28th when we return from break.



We’ve wrapped up trimester one with our quiz over multiplying decimals last week.  We’ve moved on to the challenging topic of dividing decimal numbers now.  We are spending Monday and Tuesday to practice a bunch of problems to make sure the students understand the lessons from this past week.  Students will have a study guide to work on Tuesday related to this topic.  We will have shortened classes on Tuesday and Wednesday due to our convo and field trip.  Our quiz will be on Wednesday over dividing decimals.  We will then turn our attention to the end of the unit test.  It will only cover the last 4 lessons of the unit since we had a mid-unit test back about a month ago.   The unit 1 test will take place on Monday, November 21st.


Last week of the trimester approaches us.  We will be finishing up with multiplying decimals early this week.  This will lead to the final quiz of the trimester.  Students will be expected to know how to estimate multiplying decimals, area models for solving multiplication with decimals, and how to use base 10 blocks to graph problem.

This will lead us to the final lesson of the unit, which is dividing decimals.  We will spend the remainder of the week demonstrating how to apply this concept.

We are getting close to the end of the trimester.  Time keeps on flying by.  We will be wrapping up adding/subtracting decimals on Monday with a quiz to follow on Tuesday.  I do want to mention that many students had trouble with our division quiz last week.  A makeup quiz was given Thursday.  ALL students had the option to retake the quiz.  Some students have continued to struggle with these types of problems.  It is a topic that may need further practice throughout the year in and out of the classroom.  I’ve added some extra practice worksheets on the math resources tab of the blog.

This week we will moving on to multiplying decimals Lesson #8.   This topic can be challenging since it is a new topic for students.  We will spend Tues. through Fri. working on it.  We will use models and repeated addition to help display the process visually.


"We had decimals today and I think they've followed me home!"

Welcome back from Fall Break!  We are in only a couple weeks away till the end of the trimester.  This week, we’ll be finishing up long division.  Students took a quick check assessment right before break and we will be checking it over in class.  I don’t plan on using this as a grade as some students are still having trouble on it.  We will go over it and grade it so they can see what they need to work on to get ready for the quiz on Tuesday over division.  They will also be working on a study guide to prepare them in class.  I’m putting some extra practice activities on the math resources page for some extra division work.  Students will be expected to do division using partial quotients and area model methods when solving division problems.  There are examples in the practice book (file put on math resources) and instruction book if trying to assist in going over this method.

On Wednesday, we’ll start to look at adding and subtracting decimals.  This concept should move a little quicker 3-4 days due to the difficulty level.  This will lead to Lesson #8 and Lesson #9 on multiplication and division of decimals.  I also encourage students to continue to use i-Ready at home on days of light to no homework.  Each lesson on i-Ready is 15-22 minutes long.  Our goal is to try to get close to 45 minutes in at school, but the extra practice at home will only take them further along being retaught concepts they missed to start the year.

Students will also be working on a Dynamath assignment Tuesday after their quiz.  This will turn into a grade that should be easy points.  We will have a couple station assignments that students should be able to use to pad their grade before the end of the trimester.  Also, don’t forget that students have a weekly stumper that they can use to get some extra credit!


One more week to go before Fall Break as we leave multiplication and head to division starting this week.  We will be having our lesson quiz on multiplication on Monday.  Image result for funny division picturesThe students have a study guide that we will go over along with the results of their quick check before taking the quiz.  We will then get into lesson #6 on division.  The rest of the week will be learning how to use place value,  estimating quotients, area models, and the relationship with multiplication to solve division problems.  We may quiz on Friday, but I will play it by ear to see if we can get there before break.  If not, we will wrap it up immediately when we return.

I’m also encouraging students to use i-Ready at home through the website: when possible.  We will be using it in the classroom 35-45 minutes a week too.  Also, if students are struggling or need improvement with knowing their basic facts for all operations I’m having them use  I can set them up with an account and parents can monitor progress very easily with a code I can provide.  Just let me know if you would like me to enroll them in this free program.

*One more reminder, remember students have the ability each week to earn up to 10 points of extra credit through the attempt and completion on my stumper problems that I give out in the beginning of the week.

During our shortened week, we made our way through talking about percents (%).  We discussed the relationship they have with fractions and decimals and how they are all connected.  We spent this time doing some activities demonstrating through models and tables how to relate them to each other.  We finished up on Friday with a quick check over the material.  I don’t plan on giving a quiz over it due to the shortened nature of the topic in our book.

We will start up on Monday with the topic of multiplying whole numbers.  This lesson involves multiplying 3 digit by 2 digit numbers.  In 4th grade students multiplied 2×2 digit numbers.  This section will rely on students being able to know their basic times facts in order to get through these problems.

RESOURCE for upcoming lesson

If your student struggles with these basic facts, then I’m recommending using a program called Xtra math.  The website is  I have used it to help students that I’ve worked with outside of school. I’ve found it to be very beneficial to helping them and me see which facts they know and which ones they struggle on.   If you’d like me to add your student to my account roster, please let me know and I will add them.  I will also provide you with my login info so you can work with them and monitor them on your end.  This can really provide good data points and increase self-esteem in becoming better mathematicians in the classroom.

After a big test this past week, we move on to finish unit #1 in the next month.  We have a short little lesson on percents coming up on this short week.  We will be showing the relationship between percents, fractions, and decimals.  I will be out of the classroom on Friday, which will lead to an in class assignment related to their new Scholastic isssue of Dynamath. When this magazine is used, it covers concepts that we have covered this year or they learned in previous grades.  It will be used on throughout the school year and is theres to keep each month.

Students will be getting their test back on Tuesday to go over.  It is worth 100 points and will have a big impact on a students grades.

This week will be a heavy assessment week.  We will be wrapping up our mid-point of Unit #1 early in the week and taking our quiz on it.  We will spend the mid-part of the week reviewing the first 4 units and doing a mid-point test on Friday this week.  This will take us into the back half of this unit starting at the beginning of the next week.  Here is our schedule for the upcoming week:

Monday (19th)–Quick Check on Comparing/Rounding Decimals and study guide review on lesson

Tues. (20th)–Quiz over lesson #4A and station work on decimals

Wed. (21st)–Station review on lessons 1-4A  for test

Thurs. (22nd)–whole class review for test (possible Kahoot! competition play)

Fri. (23rd)–Unit 1 mid-point Test

Also, there will be an e-mail early this week in regards to extra credit that is offered throughout the year in my class.


Another week has flown by in math.  We spent the short week quizzing over the “power of 10” last Tues. and then getting into lesson #3 reading and writing decimals.  Students were taught how to look at decimal numbers in a variety of ways.  These involved converting them into fractions and mixed numbers, word format, and expanded form.  The one that seemed to cause the most trouble for some students was the expanded form.  They were required to put a chart in their book to help them convert a decimal to a fraction and given some strategies on how to do so.  They were also given a little cheat sheet on putting them into fraction form and expanded form.

We will be quizzing over this material on Monday after we do a study guide together and review their quick check from Friday.  These quick checks are given to help see what we need to really talk about before giving the quiz.

The next lesson will be our half way point for this unit.  We will be doing a test after this next lesson (4A).

The next lesson  (4A) will involve comparing and rounding decimals.  We will be starting this lesson on Tues. (9/13).


During the previous week, we worked getting to know the 10 and the power it holds! 🙂  We started to get to know how to use exponents and their effect on the number 10.  We talked about how using 10 as a base with exponents can represent 100, 1,000, and 10,000.  There was a quick check on the concepts on Fri. and there will be a quiz after a short review on Tues. when we return.

Some students are still having trouble with multiplying and dividing fractions.  Below is a link to help with more practice.

This other link deals with problems using the power of 10 to multiply and divide decimals.

Going forward, we’ll be looking at how to write decimals as fractions and how to say them them as a mixed number too.  This lesson will go through this Friday.  We will most likely take a quiz on this next Mon. due to the short week.  We will do a quick check on Thursday to see how they are understanding the material.


This past week just flew by for us.  We finished the week with our first lesson quiz over decimals and place value.  These quizzes will be worth 50 points and assess the true understanding of the concept we have gone over in class.  Students also started working their way through an online program that is part of our math series called i-Ready.  It evaluates a students based on an initial diagnostic test they took the 2nd week of school.  They then go back and practice lessons of concepts they struggled on in the initial diagnostic.  They will take the diagnostic again 1/2 way through the year and at the end of the year to monitor progress.

This week our lesson will continue working through the relationship of decimals and fractions using the “power of 10” to compare them.  Students will also be using multiplication and division to talk about the place value between #’s.

The video below is a helpful video showing the power of 10 that we will be using in class.


Students spent the past week mainly working on assessment for math.  We did a diagnostic test as part of our new Ready math program that is being implemented this year.  This component of the program will be used to reteach and challenge students as they seek to master all 5th grade concept material.  The diagnostic test allows the program to see where a student is at and moves them along their individualized path.    We also had NWEA math to get a baseline score and a goal to shoot for by May.

Next week, as we get into our core lessons we will be starting off with place value and decimal work.  These lessons will dig in deep to help students understand how digits hold value and the values of the digits to the right of the decimal.  We will be incorporating videos, flip charts, and hands on manipulatives to help ensure they are understanding it fully.


Welcome to math with Mr. D.!  I’m very excited to teach a brand new math program for our district called Ready Math.   This new K-6 program will dig deeper into standards set forth by the state for math.  We have 5 main units and roughly 30+ lessons to conquer.  Instead of going a mile long and an inch deep with curriculum will be diving deaper below below the surface to understand the “why” that goes with the “how” in math.  Many students are able to “solve” problems, but don’t understand why they are able to do so.  The new standards and curriculum seek to fix that problem.

There will also be an online component to our math program this year called i-Ready.  It is online program/tool that allows students to be retaught or concentrate on standards/lessons that they may need additional support.  We will spend roughly 45 min. a week on our new Chromebook computers in class doing this program.  The benefits to this supplemental practice could be BIG!  It also makes sure that students get a lot of extra practice to not fall behind on concepts they’ll need for future grade levels of math.

Keep checking back for weekly classroom updates.
