Choosing a method
I have learned different methods to add and subtract.
72 + 1
6 + 6
23 – 7
11 + 54
27 – 3
36 + 6
83 – 7
59 + 22
7 + 6
Look at each of these calculations. Discuss the methods you would choose to solve each calculation. Choose one calculation. Draw a picture or diagram to explain the method.
