Length and Perimeter - Equivalent Lengths m and cm - Starter

In a mathematics lesson for Year 3 students during the Spring Term, Week 8, Day 3, children are presented with a variety of problems to solve that involve measurements and simple calculations. The "Fluent in Four" revision segment challenges students with arithmetic questions, such as finding half of the product of 16 and twenty-seven, and multiplying a number by four to reach a sum of 28. The exercises are designed to reinforce their understanding of multiplication and division, as well as the concept of halving.

Real-life application problems are also included to engage students' problem-solving skills. For instance, they calculate the combined height of two stacked towers, one built by Peter at 19 cm and another by Bryan at 37 cm, to determine the total height when Peter's tower is placed on top of Bryan's. Additionally, a scenario involving Rosie, who buys a cucumber and an onion and pays with a £1 coin, prompts students to work out the correct change from two possible amounts: 22p and 16p. The lesson also includes a comparison task where students must determine whether 50 cm is longer than, shorter than, or the same as 1 metre and 50 m compared to 100 cm, helping them understand equivalent lengths in metres and centimetres.
