What to do • Ask your child to complete each of the fact family houses. In each house, the three numbers in the roof of the house are used to write four related calculations: two addition calculations and two subtraction calculations. On the back of this sheet, help your child create two fact family houses of their own using numbers up to 20. Underneath each trio of numbers, they write the four related number facts (two addition and two subtraction). © HarperCollinsPublishers Ltd. 2014
