This is a task from the Illustrative Mathematics website that is one part of a complete illustration of the standard to which it is aligned. Each task has at least one solution and some commentary that addresses important asects of the task and its potential use. Here are the first few lines of the commentary for this task: Materials A large set of dominoes to affix to a whiteboard or place in a pocket chart, or a regular set to use on a document projector.

Each task has at least one solution and some commentary that addresses important asects of the task and its potential use. Here are the first few lines of the commentary for this task: Write as many equations for each picture as you can. Use the numbers 4, 1, and 5. Here are some equations for this picture. 4+1=5 \hskip4em 5 = 4+1 5-1...
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.

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 hands-on lesson plan, students use the analogy of a literal family (including cut-outs of boys, girls, and houses) to learn about fact families and the inverse nature of addition and subtraction.
In this lesson students will use manipulatives to learn about partners and the Commutative Property, the challenge will come when students have to figure out the way to do it using rice grains. The lesson is designed for a Spanish Immersion setting so many of the resources and lesson components will be in Spanish. This lesson was developed by Paola Contreras-Ramirez as part of their completion of the North Carolina Global Educator Digital Badge program. This lesson plan has been vetted at the local and state level for standards alignment, Global Education focus, and content accuracy.
In this lesson, students look for and make use of repeated reasoning on the addition chart by solving and analyzing problems with common addends.
