What a number bond shows

A number bond shows that a number is made of two parts: 5 is 2 and 3. Seeing the same three numbers as adding and as taking away is the start of knowing the facts by heart.

Use counters first

Put five buttons on the table, slide two to one side, and count the rest. Then fill in the bond on the page.
