Adding and Subtracting Fractions with Like Denominators

Visual models support young mathematicians as they deepen their fractional number sense in this elementary math lesson. Using fraction circle manipulatives, children explore basic unit fractions as they develop the fundamental...

Help your third graders become familiar with equivalent fractions for one-half by having them create a quilt. They will use triangles to create a quilt of equivalent fractions over a period of 6 days. As they create the quilt pieces they...

Young mathematicians utilize video, the internet, and hands-on learning experiences in order to recognize that fractions aren't as "scary" as they first appear, and that we use them every day in our lives. The hands-on activities in this...

Have young mathematicians subtracting fractions in no time with this manipulative-based math lesson. Using their sets of fraction circles, students explore a number of word problems involving the subtraction of fractions before working...

Understanding when to divide by two or one-half can be confusing. Here is an activity that gives four different scenarios. It is up to your number crunchers to decide if they divide by two or one-half. The easiest way to approach the...

This fractions PowerPoint defines and gives examples of multiples and least common multiple, then models how to list multiples and circle the least common multiple. Each step to use in subtracting fractions with unlike denominators is...

Develop a strategy for adding and subtracting fractions with your classes. The video shows a procedure for adding and subtracting fractions by finding common denominators. Each example increases in difficulty.

These presentations by Monica Yuskaitis are particularly good. In this one, she shows viewers how to deal with subtracting fractions that have unlike denominator, no small task! This is a tricky process, and this PowerPoint takes young...

Want to add fractions? Well, if they have the same denominator it's going to be so easy. Just add the numerator values together and keep the denominator the same. Easy as that.

RJ and Zoey are at camp and need to get back to the mess hall for lunch, but they don't know how far they have to walk. Help them figure out the distance while teaching young mathematicians how to add and subtract fractions with this...
