How to build number relationships:
- Use the three numbers to make + or - equations
- Try both orders for addition
- Start with the largest number for subtraction or division
- Each group can make four equations
For example, given 3, 7, 21, the 4 equations can be:
- 3 x 7 = 21
- 7 x 3 = 21
- 21 ÷ 3 = 7
- 21 ÷ 7 = 3
