Ratio - Ratio and Proportion Problems (2) - Starter

In a Year 6 mathematics lesson, students are presented with a series of problems to solve that revolve around the concept of ratio and proportion. In one activity, they compare the value for money offered by two shops selling the same pens. Safeway offers 7 pens for £8.75, while K-mart prices 8 pens at £9.60. Through calculation, students determine which shop provides the better deal. Additionally, the class is tasked with sorting a list of numbers into a table, categorising them as either prime, having only two factors (1 and itself), or composite, featuring more than two factors. This exercise includes numbers such as 7, 17, 19, 23 for prime and 6, 18, 36, 42, 88 for composite.

Another component of the lesson involves completing missing information in mathematical statements related to length and area. Students must use their knowledge of units of measurement to fill in the blanks and convert between meters and millimeters. For example, they are asked to solve problems such as adding and subtracting lengths in meters to find the equivalent in millimeters. The lesson also includes a Fluent in Four revision section, where students practice quick mental arithmetic problems, such as 18:28, and convert between different units of mass to solve a problem involving the mass of apples and pears in a juice mixture. Additionally, they calculate the perimeter of a shape given the length of each square on a grid, reinforcing their understanding of perimeter in the context of geometry.
