Are you looking for an easy way to help your first-grade students make sense of the first-grade mathematics they are learning—while seeing how mathematical concepts fit together in meaningful ways to solve real-world problems? Do you want them to develop efficient strategies without having to spend extra time planning lessons yourself? The DEEP Math program is a year-long, standards-aligned curriculum designed with exactly that in mind. Each lesson takes approximately one class period to complete and includes step-by-step directions, engaging discussions, a focus lesson, guided practice, and independent work. Every set of five lessons also includes a quiz to assess student understanding.

Why do you need this resource?

Detailed lesson plans and materials lists spell out everything you will need to present these rich and meaningful lessons that are designed with the primary goal of helping students make sense of mathematics. Your students will learn mathematics by using it, day in and day out—to form the mental images, to build the conceptual understanding, to see the connections, to become fluent in the language, and to cultivate the habits of mind—which will serve them, not only on high stakes tests, but much more importantly, for a lifetime.
