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.
These are the family letters for Grade 3 Cluster 5. These can be remixed.
In this lesson students explore how new shapes can be formed by composing other shapes. This is remixable , especially to add various supports to meet the needs of all learners.
In this lesson, students learn the attributes of triangles by constructing them from various side lengths.
In this lesson, students explore various triangles by sorting them based on attributes such as having equal lengths and square corners (right angles).
In this lesson, students explore various quadrilaterals by sorting them based on attributes such as opposite sides having equal lengths and square corners (right angles).
In this lesson, students identify and explain the attributes of a quadrilateral and use defining attributes (number of sides, angles) to name quadrilaterals.
This resource is from NC Tools 4 Teachers. Here are parent letters to send home before teaching Grade 3 Cluster 5.
These exit tickets are from Tools4NCTeachers. They provide examples of exit tickets that can be used for formative assessment. These are remixable.
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 resource is from NC2ML. It may not be remixed.This Standards Brief discusses strategies and representations second graders are taught for mult-digit addition and subtraction. This is a great reading to share during a professional development with teachers or to hand out during family math nights.

In this lesson students use the open number and various strategies to solve two-step story problems.
This resource is part of Tools4NCTeachers.
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.
