Students make the target numbers 1-20 using only the digits 2, 3, and symbols +, -, and = . It is a good idea to model this first. I have included an example-recording sheet to help you explain how to do it. The point is to teach students to look for patterns with numbers. For example, if they know how to make six by adding 3 + 3, they should recognize that to make seven they need to do 3 + 3 to make six and add one more to make seven (3 + 3 +1 = 7).
