Series: Focus on the Child
Transforming Three-Dimensional Shapes with Child 36
This child flips and rotates triangular prism-shaped blocks to match a given arrangement.
Focus on the Child videos are taken from one-on-one interviews with individual children. The interviews are designed to elicit evidence of children’s mathematical thinking. They are not teaching episodes or formal assessments.
Why is this important?
Simple transformations of 3-dimensional shapes through flipping and rotating help children construct the idea that a shape does not change even as they change its position.
