Ratio - Calculating Ratio (Activity) - Starter

In a Year 6 mathematics activity focused on ratios and estimation, students are tasked with estimating the area of a pond represented on a grid where each square is equivalent to 1 square meter. Rosie has estimated the area to be 12 whole squares, and students are prompted to consider if this is an acceptable approximation. The activity challenges them to think about how they might include the partial squares in their estimation to refine their answer. They are asked to record the number of part squares and use this information to calculate an approximate area in square meters, enhancing their understanding of estimation and area calculation.

The lesson also includes a section on translations, where students are required to describe movements on a grid using mathematical terminology. For example, they might note an object moving 8 squares to the left and 10 squares down. Additionally, students explore the concept of ratios, with exercises that involve writing down the ratios for given quantities of fruits, such as pears to apples, apples to bananas, and combinations thereof. They practice expressing these relationships in ratio form, both in part-to-part and part-to-whole contexts, reinforcing their understanding of proportional reasoning and the representation of ratios.
