Building Blocks: Developing Preschool Children's Early Mathematical Knowledge and Processes by Incorporating Mathematics into Daily Preschool Activities.

Building Blocks is a program that aims to develop preschool children's early mathematical knowledge and processes by incorporating mathematics into daily preschool activities. The program follows the mathematics learning trajectories, a sequence of learning activities that are aligned with the typical progression of how children learn mathematics. Teachers implement Building Blocks through weekly whole-and small-group instruction, center activities, and computer activities. The program also includes a letter sent home each week describing the mathematics children are learning and related activities that families or caregivers can do at home to support their child's learning. Teachers regularly assess children's learning and adapt activities to build on and extend the level of children's mathematical thinking. The program is implemented over 26 to 30 weeks, and teachers' use of the Building Blocks curriculum is supported by professional development.
