Number bonds are about creating a mental image of how a number is made up, usually by adding two numbers together or subtracting one number from another.
On the first screen you are able to choose the number bond game to play from a drop down list, with numbers from 10 to 100 in tens. Once you have chosen, then click on the Play Addition or Play Subtraction button to play adding or subtracting number bonds.
In the game you have chosen you are presented with a Hoopla game of pegs with different values above them. At the top of the screen you are shown a sum or problem with a missing number. Using your mouse, click on the number peg that you believe is the answer. For example 5 + ? = 10, the answer is the number 5, so you would click on the 5 peg. Your mouse pointer will turn into a hand when over any peg on the board.
