Daily Practice and Problems

The Daily Practice and Problems (DPP) is a set of short exercises that provides a structure for ongoing review and study of math concepts, skills, and math facts. To support this daily routine, at least two DPP items are included for each class session. Nine icons designate the subject matter of the DPP items.

You and your students will need: Addition Flash Cards: Group C, Addition Facts I Know chart, 100 Chart, 20 connecting cubes, a 12-inch ruler, a 25-link chain of connecting links, and number lines.


Distribute DPP items to students. Display and read each item to prepare students
to work independently. Follow with a class discussion of their solutions and strategies.

Practice of the Addition Facts

Some DPPs focus on the development of the addition facts and the related subtraction facts. See Figure 1. See the Letter Home for more specifics about the math facts strategies developed in the DPPs in this unit.
