Part of the Usborne Key Skills series that supports the maths lessons children learn at school, this book is filled with activities that help children understand the value of each digit in a number (place value), and provide practice in adding and subtracting 2-digit and 3-digit numbers in columns. Wipe-clean pages offer endless practice, and answers and secret notes for grown-ups are at the back.
