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 2 OF 3 - This video addresses NC standard 5.NF.1. It explains strategies for making estimates when adding and subtracting fractions with unlike denominators. Strategies for making estimates before and after problems solving are provided.

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 brief video shows students how to enter a fraction into the TI-15 calculator and to add fractions. Students should access to a TI-15 calculator while viewing, This video may be embedded within Google Classroom.

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.

In this video, a student explains how to use the area model for multiplication. The area model is a multiplication strategy based on decomposing numbers basedon place value.

Each attachment contains a different version of the counting students task. Each task requires students to count on from a given number. Tasks may be used for instructional or assessment purposes.

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 11 in a series of 12 lessons around fraction equivalences and comparisons.

This video lesson reviews parts of a whole, comparing fractions, and equivalent fractions. No materials are needed.

This lesson is Day 12 in a series of 12 lessons around fraction equivalences and comparisons.

Use your math skills to help detectives solve the crime. This video lesson reviews fractions of an area, fractions on a number line, and equivalent fractions. No materials are required.

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 1 in a series of 5 lessons around U.S customary measurement.

This lesson focuses on measuring lengths to the nearest fourth of a inch, and discusses when it's necessary to find a precise measurement versus an estimate.
