Activity
Activities 1 and 2
These activities involve informal relations where one or more of the variables is difficult to quantify. Discuss Jack’s graph to help students interpret the information in it. A rectangular piece of paper can make reading the graph easier.
In Activity 2, students’ graphs will vary, but encourage them to explain their graphs to others to facilitate peer assessment. It is vital that students explain the position of points to establish whether they understand ordered pairs.
Activity 1
Answers will vary. Some things make Jack very happy (for example, finding gold), and other things make him sad.
Activity 2
Answers will vary.
