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.

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.
