Multiplication and division - Scaling - Starter

This set of exercises from a Year 3 maths lesson focuses on multiplication, division, and scaling. The 'Fluent in Four' revision section challenges students with quick multiplication problems, such as doubling the product of 4 and 7, and finding the missing factor in a multiplication equation that results in 18. The practical application of division is explored through a problem where students must determine how many squares can be formed from 78 sticks, requiring them to divide 78 by 4 and work out the remainder. This not only tests their division skills but also their understanding of grouping and remainders.

The lesson continues with real-life application problems to help students understand scaling and comparative measurements. For instance, they are asked to calculate the length of a plane that is 9 cm longer than a 14 cm fire engine, and to find the length of a car that is half the length of the same fire engine. These problems reinforce the concept of addition and halving in a tangible context. Additionally, students are presented with a scenario where they must figure out how many more pounds Leanna has compared to Rosie, further practicing their subtraction skills. The lesson is structured to build on each concept progressively, ensuring that the students are not only fluent in their calculations but also able to apply mathematical concepts to everyday situations.
