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.
