Module 4: Take From (up to 20)Math 2A  Course Guide
Module Overview:
In this module, students will identify parts of a subtraction sentence, identify pictures that represent given subtraction sentences, and create pictures based on subtraction sentences. They will identify a doubles subtraction fact using doubles addition facts, recognize subtracting doubles as a helpful subtraction strategy, practice subtracting doubles, identify if the missing number in a subtraction sentence is a part or the whole, and find the missing number in a subtraction sentence using a partpartwhole chart. Students will represent the part of a subtraction sentence on a number line, use a number line to find the difference in a subtraction sentence, relate addition and subtraction sentences and recognize fact families as number sentences with the same 3 numbers.
