  1. To formulate an equation to solve the word problem.
  2. To understand different problem solving strategies.
 
  1. Ask students to work independently for parts (a) and (b) of the worksheet.
  2. For parts (c) and (d), can help students divide into groups to discuss.
  3. Problem (d) is more challenging, suitable for abler students.
  4. Invite some students to present their results.
 
  1. In this activity, students are expected to develop HOTS including problem solving and communicating skills.
