The purpose of this activity is to engage students in using volume/capacity calculations to solve a problem.
This activity assumes the students have experience in the following areas:
The problem is sufficiently open ended to allow the students freedom of choice in their approach. It may be scaffolded with guidance that leads to a solution, and/or the students might be given the opportunity to solve the problem independently.
The example responses at the end of the resource give an indication of the kind of response to expect from students who approach the problem in particular ways.
Frieda wants to make 2-serving sized bundles of pasta to store in the freezer.
Her pasta recipe requires 2 eggs and 1 cup of flour for three servings.
She has one dozen eggs to use. How many bundles can she make?
How much flour will she need?
The following prompts illustrate how this activity can be structured around the phases of the Mathematics Investigation Cycle.
Introduce the problem. Allow students time to read it and discuss in pairs or small groups.
Discuss ideas about how to solve the problem. Emphasise that, in the planning phase, you want students to say how they would solve the problem, not to actually solve it.
Allow students time to work through their strategy and find a solution to the problem.
Allow students time to check their answers and then either have them pair share with other groups or ask for volunteers to share their solution with the class.
The student systematically follows a series of calculation steps to find the solution to a proportional reasoning problem.

The student uses calculations to scale the ingredients in the recipe for pasta up and down and finds a correct answer independently.

The student creates the equivalent of a ratio table to organise the scaling of ingredients in the recipe. They find a correct answer independently.
