# Decomposing Fractions

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 site also has a video included on the right side 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.

# Beware of Key Words!

It is important that students comprehend the question that is being asked in a word problem. Kids can no longer rely on “key words” to know how to solve a problem. The video below shows why students need to BEWARE OF KEY WORDS!

# “Big 7” Division

In this process of division, students divide using whole number place value instead of just using the digits. We began working on this yesterday, and many students find that it is much easier than the traditional steps of long division.

# Long Division Videos & Practice Links

We are working hard to learn the process of long division. Here are a couple of videos that we’ve watched in class:

Click below for a link to 5 websites that can be used to practice long division.

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.

# 2 X 2-digit Multiplication

We are currently 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!
