The Use It! Don’t Lose It! Daily Practice Series helps your students use their skills, so they won’t lose them! There are five problems a day, every day, for 36 weeks. The practice activities are set up in a spiraling scope and sequence so that students practice skills at regular intervals. Each week problems are based on a grade-level appropriate topic so every time a skill shows up, it has a new context, requiring students to dig into their memories, recall what they know, and apply it to a new situation. Correlated to state and national standards, this six book series provides daily math and daily language practice.
