A Numberbond is 2 different numbers that add up to make a certain number. Can you collect up 10 of the same item. Small blocks work well, but you can use anything. Can you then separate the 10 items into 2 groups. Count how many you have in each group. This is a numberbond to 10. Repeat with different amounts. Each time you separate the amounts can you write a number sentence to represent it for example
2 + 8 = 10
