Lesson details

Key learning points

  1. Equal parts may not look the same
  2. The whole has been divided into __ equal parts
  3. One equal part is shaded so each equal part is __ of the whole

Common misconception

Children might find it hard to create their own puzzles in the final part of Task B as the dotted lines can be overwhelming.

Model the process heavily for those who need it, where possible using a visualiser and sharing finished examples. Make good use of the template. A bigger version can be found in the additional materials.

Keywords

  • Whole - The whole is all of a group or number.

  • Part - A part is a section of the whole.

  • Equal - Have the same quantity or value.

  • Unequal - Do not have the same quantity or value.

You might find that tracing paper is useful here to help children with visualisation. They can trace over one part and use it to see how many fit into the whole. Also, you might wish to give them stencils or templates when it comes to creating their own puzzles for no. 3 on Task B.
