2D Shape Puzzles - Sort by Number of Sides

2D Shape Puzzles - Sort by Number of Sides
Shape Resources

In this set of '2D Shape Puzzles', students are required to sort each shape by the number of sides. They will understand that shapes can be described as 'regular' or 'irregular'.

Lesson Structure
  • Individual Activity
  • Rotations / Group Work


Remove some of the shapes, only focusing on two puzzles for students to complete before extending to add more puzzles.


Encourage students to identify and describe the two-dimensional shapes as either 'regular' or 'irregular', e.g. 'This shape is a regular pentagon because it has five equal sides and five equal angles.' Once students have completed puzzles, they can draw an example of each shape and list its attributes.
