Length and height - Measure length 2 - Starter

In a Year 1 mathematics lesson, the focus is on measuring length and developing fluency in foundational arithmetic skills. The lesson begins with a 'Fluent in Four' revision exercise, where children practice their subtraction skills with simple equations such as "11 minus 8" and "Twelve minus half of 14," providing a quick and engaging way to warm up their numeracy abilities. This activity not only helps students reinforce their understanding of subtraction but also introduces them to the concept of halving numbers in a practical context.

As part of the lesson, students are presented with a practical application of their learning through an exercise that involves ordering the length of crayons from the shortest to the longest. This task helps children grasp the concept of comparing lengths and understanding ordinal sequences. Additionally, the lesson includes a real-world problem-solving scenario where Rosie has 15 apples and wants to divide them into groups of three. Students are asked to determine if Rosie's assertion of ending up with five groups is correct, which it is. This exercise not only tests their division skills but also reinforces the idea of equal grouping, a fundamental aspect of early mathematics education.
