Puzzles are more than just fun—they’re powerful tools for building spatial reasoning, a key foundation for strong measurement skills. When children rotate pieces, look for patterns, and figure out how shapes fit together, they’re practicing the same mental skills they’ll later use to compare lengths, estimate distances, and understand area and volume. Jigsaw puzzles, tangrams, and even block-building challenges help kids visualize objects from different angles and make sense of how parts relate to a whole. By including puzzles in your family’s routine, you’re supporting the kind of flexible thinking that helps children confidently tackle measurement tasks at school and in everyday life.
Challenge: Use a single, straight-line to cut this shape into two pieces that can be arranged into a square.
