The document describes 3 conservation exercises testing children's understanding of numbers, liquids, and mass. The number exercise involves rows of pennies in different arrangements. The liquid exercise uses identical and differently sized glasses. The mass exercise presents play dough in balls and snakes. For each exercise, the document records the responses of 4, 5, and 6-year-olds and the thinking skills involved in their responses, such as perception-based thinking.
