Lesson 10
Learning Outcome
- Use mathematical models to solve a complex volume problem.
Language Outcome
- Write a full explanation of the methods used to solve a complex multi-step problem, using the language of instruction.
- Talk about findings and methods to the rest of the class using past tense verbs.

Principles 2, 3

What is the volume of a person?
- Organise the students into groups of 3-4. Give each group a large piece of paper for them to record their working and method and a tape measure. Explain to the students that they are going to find the volume of one person in their group. Give them 2 minutes to discuss who they will measure and how they will solve the problem. Circulate around the groups. Ensure that each group is engaged in the problem and has selected their person to measure (the teacher may need to volunteer if students feel sensitive about being measured).
- Hold a brief class discussion to share ideas on methods to calculate the volume of a person. What mathematical models will they use? Encourage the groups to set their work out clearly so that someone else can follow their working. Discuss the language of mathematical instructions.
- Students have 15-20 minutes to complete the task. Circulate the class. Students may need help to find the radius when they have measured the circumference.

Report back
- When all groups have finished, each group explains the methods they used.
- Discuss the accuracy of each answer. How can we improve the accuracy of this answer? Can we check the answer by finding a person's weight? What assumptions are we making if we do this?
