VIDEO 3 OF 3 - This video addresses NC standard 5.NF.1. It explains how to connect the use of models for addition/subtraction of fractions to the standard algorithm for adding/subtracting fractions.
VIDEO 1 OF 3 - This video addresses NC standard 5.NF.1. It explains WHY we create equivalent fractions when adding unlike denominators, and HOW to create equivalent fractions when adding unlike denominators.
This is one possible method for using the area model for division.
With this division strategy, students divide by breaking the dividend into its expanded form. Then, students use familiar multiplication facts to divide. It is suggested that this would be the first of three strategies for division (preceding partial quotients and the standard algorithm.
This lesson is Day 10 in a series of 12 lessons around fraction equivalences and comparisons.
This video lesson serves as a review of equpartitioning in order to determine the fractional part of an area or length. This is a necessary foundational skill for comparing and finding equivalent fractions.
This lesson is Day 1 in a series of 5 lessons around U.S customary measurement.
This 3rd grade video lesson introduces the U.S. customary measurements for length: inches, feet, and yards. In this lesson, students will learn benchmarks (visuals) for measuring in inches, feet and yards when they don't have standard measurement tools available.
This lesson is Day 1 in a series of 12 lessons around fraction equivalences and comparisons.
This video lesson encourages students to reason about and visualize fractions. The lesson focuses on the ideas that fractions are fair shares and that fractions can be compared. This lesson assumes that students have some initial experiences with fractions.
This lesson is Day 2 in a series of 12 lessons around fraction equivalences and comparisons.
This video lesson uses paper folding to introduce the concept of equivalent fractions. To complete this lesson, make sure you have a square piece of paper (any size) and a crayon
This lesson is Day 2 in a series of 12 lessons around fraction equivalences and comparisons.
This video lesson introduces the idea that fractions can be used to represent 1 whole. To engage in this lesson, students may use virtual circle models from Toy Theater (https://toytheater.com/fraction-circles/)
This lesson is Day 4 in a series of 12 lessons around fraction equivalences and comparisons.
This video lesson looks at how we use fractions in the kitchen. Students are challenged to use circle models to find equivalent fractions for a recipe. Students may use virtual circe models from the Toy Theater (https://toytheater.com/fraction-circles/).
This lesson is Day 2 in a series of 12 lessons around fraction equivalences and comparisons.
This game may be played with one or two people. It reviews fractions on a number line, adding fraction with like denominators, and equivalent fractions. For an extra challenge, you can even break up your moves across multiple tracks (e.g., if your card reads 1/2, you could move 1/4 and 2/8).

The area model can be used when multiplying any two numbers, including decimals. This video demonstrates how to multiply using the area model when a decimal is involved.
This Thinglink provides a series of brief videos addressing a) common areas of difficulty related to problem solving and b) an overview of additional and subtraction problem types.

In this lesson, students create a "train" (or row) of shapes. Each shape in the row must have one attribute in common with the shapes on either side.
