Free Y3 maths worksheet: Making 100 by adding

Here is a straightforward worksheet which is more open ended. It allows the child to find two numbers which add up to 100. Some children will work in a well ordered methodical way eg by adding whole tens 90 + 10, 80 + 20, 70 + 30 etc whilst others will choose a more random approach.

Watch out for incorrect sums that add up to 110 eg 45 + 65.
