Shape Naming and Sorting

Help Manaia and Nathan sort the shapes for their bookshop display. Look carefully at each shape. You can use shape names such as triangle, square, rectangle, circle, cube, sphere and cylinder.

Look at each shape and think about its sides, corners or curved surfaces.

1.The first label in Manaia’s display shows a shape with 3 straight sides and 3 corners. What is the shape called?
