My students find using the triangles helpful when figuring out the fact families. Using this strategy will help with addition and subtraction problems.
These squares can be cut in half to create triangles. There are different colors for the different combinations for each number from 5 to 20. The triangles can be used independently for practicing the 4 number sentences and determining the numbers of the fact family, or they can be used for matching the number sentences with the correct fact family.
I have included a black and white set for those who prefer to use colored paper or cardstock for printing.
It you laminate the cards, they can be written on and the matching number sentences or fact families can be added by the students on the back. They can then self check by finding the matching cards.
