Disclaimer: Some books in our 3 for 2 clearance sale may have minor imperfections, such as slight creases or scuffs. These are purely cosmetic and do not affect the enjoyment of the book. Part of the Usborne Key Skills series that supports the maths lessons children learn at school, this book helps children understand the properties of a wide variety of 2d shapes, as well as how to draw, reflect and move them on a coordinate grid. Wipe-clean pages offer endless practice, and answers and secret notes for grown-ups are at the back.
