Decimals - Writing Decimals Numbers - Starter

Year 4 students are introduced to the concept of writing decimal numbers through a series of engaging activities. The lesson, which takes place in the first week of the summer term, begins with a 'Fluent in Four' revision exercise, designed to consolidate students' understanding of multiplication and mental arithmetic. The task requires students to find the missing numbers in multiplication equations, such as finding the number that, when multiplied by 6, equals 42, and working with larger numbers such as 64 and 96. The '9 to 5' section challenges students to calculate the difference between two numbers, enhancing their subtraction skills.

The lesson then shifts focus to fractions, where students are asked to complete a set of equivalent fractions, all equating to one third. This exercise helps them grasp the concept of different fractions representing the same value. To further their understanding of decimals, the students complete part-whole models, breaking down numbers into their decimal components. For instance, they explore how the numbers 0.9 and 0.11 combine to make 1, and similarly, how 0.1 and 0.89 sum up to 1. These activities are designed to reinforce their numerical fluency and comprehension of decimals and fractions in a practical context.
