Module 6: Place Value, Comparison, Understanding Income with Addition and Subtraction to 100 Overview

Module 6 builds on the place value understanding from previous modules. Students extend their understanding of tens and ones to mentally find 10 more and 10 less, compare numbers to 100, and count and write numbers to 120. They name a hundred as a new place value unit and compose and decompose numbers within 120 by using both concrete and pictorial representations. Students identify coins and their values, apply their understanding of tens and ones to explore the decomposition of coins and add a mixed set of coins. They also explore income and gifts, spending and saving, needs and wants, and charitable giving. Students will continue their work of adding and subtracting within 20 in the context of financial literacy. At the end of this module, students work with varied problem types. These include the challenging compare with bigger or smaller unknown problems, in which the words more and less suggest the incorrect operation.
