Activity

In this game, students use estimation skills. They keep improving on the estimates they have made until they get the number on the green.
Game
After students have played the game several times, you could ask them whether they have worked out the most efficient way to play the game. If they haven’t worked out that the quickest way to move between numbers with very different values is to use multiplication or division, you could remind them that multiplication is a repeated addition and division is a repeated subtraction.
As a variation to the game, students could suggest pars for each hole and classmates could try to match the par. Another challenge could be to get a “hole in one” for a particular hole. Note: The course would have to be designed so that a “hole in one” is possible.

Answers to Activity

1. There are many possible answers. Two possible answers are:
First shot: 14 x 4 = 56
Second shot: 56 + 7 = 63
Total number of shots = 2

First shot: 14 x 3 = 42
Second shot: 42 x 3 = 126
Third shot: 126 ÷ 2 = 63
Total number of shots = 3
2. Answers will vary, but the most common will probably be when the number on the calculator is higher than the number on the green.
Game
A game of addition, subtraction, multiplication, and division
