## Overview

*Think Math!* is founded upon the principle that children are curious problem solvers. Each grade level’s content builds a puzzler’s disposition, developing mathematical “habits of mind” through games, puzzles, mental math, and other collaborative activities – with the goal of providing engaging and motivating experiences for a community of diverse learners.

In *Think Math!*, fifth graders solidify their understanding of operations using whole numbers, fractions, and decimals. They explore factors, multiples, and divisibility. Efficiency with the standard algorithm of multiplication is reached while the process of division is explored further, extending to two-digit divisors. Fifth graders add and subtract “like” and “unlike” denominators, experiment with fractions as actions, and multiply fractions. They also expand upon their understanding of decimals (to thousandths) and develop fluency with decimal operations.
