For many years, students were simply given times tables to memorize. Today's students are taught to understand not just the answer to a multiplication question, but also how they arrived there. This set supports this new method of learning and makes it even more fun with a blue Monster named Mo! Readers learn the basics of multiplication alongside Mo, including their times tables with multiples of 2, 3, 5, and 10. Visuals aid readers in practice problems and a concluding answer key allows them to check their work.
