This parent guide supports parents in helping their child at home with the 1st Grade Math content.

This resource accompanies our Rethink 1st Grade Math Operations and Algebraic Thinking unit. It includes ideas for use, ways to support exceptional children, ways to extend learning, digital resources and tools, tips for supporting English Language Learners and students with visual and hearing impairments. There are also ideas for offline learning.

This unit was created by the Rethink Education Content Development Team. This course is aligned to the NC Standards for 1st Grade Math in Operations and Algebraic Thinking.

For this interactive, students place numbers on the scale to make the number sentences true.

This resource is part of Tools4NCTeachers.

Math games are fun, motivating, and provide opportunities for students to build number concepts, reasoning, and fluency. These games may be used as math stations or as whole group learning opportunities. This file contains directions and materials for Cluster 2 math games.

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.

In this Khan Academy interactive, students will apply understanding of the equal sign to determine if equations involving addition and subtraction are true.

This task helps students understand the meaning of the equal sign and to use it appropriately.

Students will sort the tiles and place them in the correct category. Equal or Unequal

In this lesson, students strategize and apply understanding of the equal sign to solve equivalent expressions.

Students solve addition and subtraction problems to 20 by counting all the objects in their head.

This activity was based upon the book James and the Giant Peach, however, it is not necessary to read the book to complete the adventure. The slides are comprised of review skills for first grade students in reading and math. Audio clips were from bensound and mixit. All images were obtained through google images. Go on an adventure with James and the Giant Peach. Complete each task by solving the problems and clicking on the links to find James' happy ending.

Students will apply understanding of the equal sign to determine if equations involving addition or subtraction are true.

This document is the About the Cluster document created by the authors of the NC2ML Instructional Frameworks. Read this document prior to teaching the cluster in order to get insight into the clustering of the standards, mathematics to be taught, and important considerations.

This document is not remixable since the document has been written by creators of the NC2ML Instructional Frameworks.

This unit of 1 number and operation lessons explores addition and subtraction on the number line. The unit contains 3 activities.

This unit of 1 number and operation lessons explores equations using Unifix cubes. The unit contains 2 activities.

The interactive pan balance uses multiple shapes with different values, allowing students to investigate what happens as different shapes are placed on the balance. This student interactive, from Illuminations, provides an interesting environment in which students can consider the concept of equivalence.

The Family Letters are intended to be sent home at the beginning and middle of the cluster. They 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.
