These are great ways to practice your number bonds and times tables. Cut out
a set. Hold a triangle by covering one corner. On a number bond to 10 triangle
if you cover the 3 at the bottom you are asking what goes with 7 to make 10 or
10 - 7. If you cover 10 you are asking what does 7 and 3 make?
If you are using the 2x set and cover the 4 you are asking what is 8 divide by 2
or 2x what makes 8. If you cover the 8 you ask what is 2x4 or 4x2.
