The purpose of this activity is to engage students in applying their number knowledge to solve a measurement problem.
In readiness for this problem, the students should have familiarity with each of the following components of mathematics. The problem may be solved with different combinations of these components.
- multiples of ten
- finding one tenth of a value
- understanding that 10% = 1/10
- skip counting in 5s
- multiples of 5
- knowledge of the mL as a unit of volume
This activity may be carried out with guidance, or by allowing the student to follow their own method of solution. The approach should be chosen in sympathy with students’ skills and depth of understanding.
The procedural approach (show more)
- The student is able to follow a sequence of calculations, involving measurement and proportion, leading to a solution.
Prompts from the teacher could be:
- What does 10% mean?
- Can you find 10% of 350 mL?
- How many lots of 5 mL is this?
- How many teaspoons of sugar are in this can drink?
The conceptual approach (show more)
- The student is able to construct a sequence of calculations, involving measurement and proportion, leading to a solution.
