We have begun our fractions unit, and one of the first skills we are learning about is how to decompose a fraction. Until recently, “decompose” was a word that I applied to science–not math! “Decompose” means to break down or break apart into smaller parts, and I’ve learned that we can apply that word in math, too! Parents–we did learn this in school, BUT–we just didn’t use the same vocabulary. Below are a couple of sites that provide the students with practice decomposing fractions. The Khan Academy and Nearpod sites have videos included in case the students (or the parents) want to know more about the skill. 🙂 Just click on the picture and that will take you directly to the practice.
We are excited to announce that our Math night has been rescheduled for Tuesday, February 11th from 6-7 pm in the elementary gym! This is sure to be a fun night full of even more games and prizes! Every intermediate student who attends will get a hat pass good for the next day!

It is extremely important for 4th grade students to be fluent with their multiplication facts. Students may use the XtraMath program to help improve their multiplication and division fact fluency. We try to work on this every day in class, but it may also be done at home.
This is a video made by another teacher, Christine Munafo, explaining the process and steps of long division. We have watched this in the classroom, but this will provide an excellent review for your child.

We have been working hard on learning and practicing the process of multiplying up to 4 digits by 1 digit and 2 digits by 2 digits. Just learning how to use the “old school” algorithm to solve the problem is no longer enough. The kids have to be able to explain the process of why that “old school” algorithm works. I’ve posted short video clips that help to show the multiplication process and what we are expecting the kids to understand and do.Of course, it is extremely important that the kids learn and memorize their basic multiplication facts!
