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.
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 unit is to be used with second grade students to teach addition and subtraction strategies, or remediate with students needing extra practice.
This video was created by NCDPI. This video examines best practices and research related to developing computational fluency. Teaching strategies and tips are provided.
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).

In this lesson students use the open number and various strategies to solve two-step story problems.
This resource is from Tools4NCTeachers. In this lesson, students will be figuring out the addends that add up to the correct sums. They will also be creating and solving equations with more than two addends.Extension and differentiation ideas are provided.

In this lesson, students solve a word problem using a strategy of choice and share the strategy to develop the concept of representing and solving problems involving addition and subtraction within 20. This problem type will likely provide an opportunity to explore the commutative property with students. This lesson format may be used with any problem type appropriate for the grade.

This resource is from Tools4NCTeachers. In this lesson, students develop strategies for adding 3-digit numbers, with a focus on adding in chunks. Students build this strategy of adding in chunks by mentally adding 10 and 100 to numbers, and adding on the number line. Remix this lesson to include extension activities such as math stations.

In this lesson students use the open number line and various strategies to solve addition story problems.
This resource is from Tools4NCTeachers.This file contains sample anchor charts to create with students. Anchor charts are to be made with students, then displayed as a classroom reference. Parents may also benefit from seeing anchor charts, as they provide a snapshot into the math class.Remix this resource to include pictures of your own anchor charts.
