Module 1: Addition Strategies-Math 2A - Course Guide

Module Overview:

In this module, students will define addends and sums, identify where the addends and sums are in an addition sentence, add to 20, and use different addends to add to 20. They will also find the sum of an addition sentence using the counting-on strategy, find the sums of doubles addition facts, use doubles facts to solve near- doubles addition facts, and use counters and drawings to show doubles and near- doubles facts. Students will define the vocabulary words “addend” and “sum,” correctly insert dots in a ten frame to represent an addition sentence and add to 10 using various addends in a ten frame. Finally, they will fluently add up to 10 using various addends in a ten frame and add up to 20 using various addends in two ten frames.
