Students will build on their existing math foundation as they learn about units of measurement, fractions, data and statistics, decimals, expressions and equations, geometry, geometric measurment, operations and whole numbers, ratios and proportions, and whole numbers. Each book includes an exciting narrative to help make math fun, including parodies of Alice in Wonderland and the Wizard of Oz. Math problems posed throughout the stories and "Show What You Know" questions and answer pages help young mathematicians demonstrate the skills they've learned!.
