AO1: Reason with linear proportions.

In this unit we use the theme of drinks to develop an understanding of ratios. It is suitable for students working at Level 5 of the curriculum or Stage 8 of the Number Framework. The unit provides a sequence of demonstrations and questions to help guide students' learning. It includes activities that require students to convert between the metric units for capacity, and to use their knowledge of fraction, decimal and percentage conversions. Students use proportional thinking to explore, compare and combine ratios. The unit concludes with a session on rates (a subset of ratios).
