Further Challenges

• Having drawn the shapes that the nest box was made from, how might you describe them without naming them? Do the shapes have right angles? Do the shapes have parallel or perpendicular sides? Do the shapes have symmetry? Try sitting back-to-back with a partner, with one person describing a shape and the other drawing it.
• Making Maths: Birds from an Egg is a fabulous challenge on the NRICH website, which will encourage you to look closely at an image and see different shapes within it.
