This short video and interactive assessment activity is designed to teach fifth graders about comparing fractions using lcm - word problems.

This short video and interactive assessment activity is designed to teach fifth graders about comparing fractions using a fraction bar illustration.

This task is meant to address a common error that students make, namely, that they represent fractions with different wholes when they need to compare them. This task is meant to generate classroom discussion related to comparing fractions. Particularly important is that students understand that when you compare fractions, you implicitly always have the same whole.

This video explains how to compare fractions with the same denominators using the meaning of a fraction.

This video explains how to compare fractions with the same numerators without using the LCD.

The purpose of this task is to help develop students' understanding of addition of fractions; it is intended as an instructional task.

The focus of this task is on understanding that fractions, in an explicit context, are fractions of a specific whole. In this problem there are three different wholes: the medium pizza, the large pizza, and the two pizzas taken together.

The purpose of this task is for students to compare a number and its product with other numbers that are greater than and less than one.

The purpose of this task is to have students think about the meaning of multiplying a number by a fraction, and to use this understanding of fraction multiplication to make sense of the commutative property of multiplication in the case of fractions.
