Subtraction is taking away
Subtraction is taking away. Start with a number of marbles and take away some of them, how many have you got left? This is subtraction.
Cross out the marbles to find the answers to the questions.
Fill in the sums by crossing out the shapes.
Number pairs to 10
Once you know your number pairs to 10 they can help you work out sums. If the sum starts with 10 marbles it can be easy to work out.
Remember, this only works if the sum starts with 10.
Fill in the answers using the number pairs to 10.
Number pairs to 20
The same rule applies to number pairs to 20. If the sum starts with 20 it will be easy to work out in the same way as we did with the 10 number pairs.
Try answering the questions subtracting using the number pairs to 20.
