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.
The Family Letters explain big ideas of the cluster using family-friendly language. Families can also find tips for working with their children at home, digital games, videos, and books. This file contains both English and Spanish versions of the Family Letters.
This resources is from Tools4NCTeachers.Conceptual subitizing is recognizing smaller groups and adding them together, such as two dots plus two dots equals four dots. This set of dot cards helps students develop their ability to conceptually subitize. Use these with your daily math warm-ups or with any lesson focused around subitizing.
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.

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. This file contains a set of 4 tasks (including scoring rubric and student recording sheet). The tasks may be used for instruction or assessment.Remix this resource to include student work samples or addtional tasks.

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.

This lesson should occur after the Partner Quick Flash lesson, which introduces conceptual subitizing. Candy Quick Flash continues to encourage conceptual subitizing an efficient way to find "how many".
Notes:
Perceptual subitizing: instantly recognizing "how many" in a set
Conceptual subitizing: efficiently finding "how many" by recognizing and combining subgroups within a set
