This before and after number activity is a fun way for students to recognise large numbers. It then requires students to add and subtract either the number 10 or 100 to the given number on the card. They are colour coded from the numbers 100 up to 300. It also allows for differentiation with blank number cards provided.
These print out 4 per A4 page.
