2-D shapes (age 6+)
Identify and describe properties of 2-D shapes including the number of sides and line symmetry in a vertical line
Typical age: 6–7 years
“Can your child count the sides of a shape and say whether it has a line of symmetry — for example, knowing that a rectangle is symmetrical but a scalene triangle is not?”
