These number formation cards help children learn how to form their numbers correctly. Each number shows the starting point, and arrow prompts guide the rest of the number formation. The child can practise by tracing each number on the card with a whiteboard marker. You can erase the traced number using a damp cloth. The cards are A5 sized, durable and wipeable. There are 11 cards in the set, featuring the numbers 0 to 10. A whiteboard marker and cloth are not included.
