It is a game of skill, concentration and knowing your number bonds
with an added element of chance.
Good number hunting and Good Luck!
Where does the maths come in?
The numbers on the card are either a single number or a short number sentence such as 5+3. You have to match two cards that have the same total. Are some number bonds easier to remember than others? Find out which number bonds you need to get to know better.
