Classifying shapes by properties
Compare and classify geometric shapes based on their properties and sizes; understand that attributes belonging to a category also belong to all subcategories; classify two-dimensional figures in a hierarchy based on properties
Typical age: 10–11 years
“If someone asks your child "is a square also a rectangle?", can they explain why the answer is yes — because a square has all the properties of a rectangle plus equal sides?”
