Fact family worksheets
Three numbers in a triangle make four facts: two to add or multiply and two to subtract or divide.
About this worksheet
Each triangle holds three numbers that belong together, such as 4, 9 and 13. Students write the four facts they make (4 + 9, 9 + 4, 13 − 4, 13 − 9), or find the number missing from each fact.
Choose addition and subtraction families (sums up to 10, 20, 50 or 100) or multiplication and division families (factors up to 5, 9 or 12). The worked example is built from your settings and the answer key fills in every box.
