Sorting Rocks with Child 31
A student organizes rocks into different groups based on their unique characteristics.
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.
