Intervention Report on Building Blocks

This What Works Clearinghouse intervention report summarizes the evidence on Building Blocks, a mathematics curriculum that seeks to develop preschool children’s knowledge of mathematics using activities that are intentionally sequenced based on the developmental progression of children’s mathematical learning. The Building Blocks curriculum includes whole- and small-group instruction, center activities, and computer activities, as well as activities for the children’s families to do at home to support classroom learning. Teachers’ use of the Building Blocks curriculum is supported by professional development. The WWC identified seven studies that investigated the effectiveness of the program. Of these studies, three meet WWC standards and contribute to the summary of evidence in this intervention report. The research provides moderate evidence that Building Blocks improves mathematics achievement.
