This engaging problem-solving activity introduces students to goal-free questioning through a real-life context involving screen wash for a car. Students are given information about two different mixtures: a winter mix of 1 part screen wash to 2 parts water and a summer mix of 1 part screen wash to 5 parts water.
Rather than being given a specific question to answer, students are encouraged to decide what questions they could ask and investigate using the information provided. The resource includes space for students to record their own questions and solutions, encouraging them to explore the mathematics in different ways.
A great resource for developing problem-solving, mathematical curiosity and independent thinking, while reinforcing students’ understanding of ratio.
