Decimals - Tenths on a Number Line - Starter

In a mathematics lesson designed for Year 4 students during the Spring Term, Week 9, Day 5, the concept of decimals, specifically tenths, is explored using a number line. The 'Fluent in Four' revision activity challenges students to identify the number of ones and tenths in a given decimal. They are required to write out the decimal represented and create a partitioned number sentence to demonstrate their understanding of the value of each digit within the decimal. For example, with a decimal like 0.11, students would identify that there are 0 ones and 11 tenths, and the partitioned number sentence would reflect this breakdown.

The lesson further reinforces decimal knowledge through various exercises. Students complete sentences that involve adding whole numbers to tenths, such as 2 plus 0.6, to find the sum, which in this case is 2.6. Additionally, they learn to interpret scales by identifying the increments and using this information to determine the weight of objects, such as bananas, which might weigh 5.9 kg on a scale with 100 g increments. Practical application of decimals is also covered; for instance, if Cara buys a fire truck for £11 and 39p and pays with a £20 note, students calculate that she would receive £8 and 61p in change. These exercises are designed to build confidence in working with decimals and understanding their real-world applications.
