Through block play, kids learn about such concepts as balance, gravity, weight, volume, classification, patterns, similarities, differences, measurement, size, shape and fractions. They experiment, hypothesize and problem-solve, all in the context of play. They experience cause and effect and learn the value of planning ahead. They learn about risk-taking. Like any open-ended toy, blocks can be used in a myriad of ways, becoming a castle one day and a farm the next.
Blocks extend and enrich the play value of other toys like cars and dolls and animals.
The possibilities are endless. When children share a set of blocks they develop negotiating skills and learn the value of cooperative work.
