Max Maths, Year 5, Try it, Review of finding pairs of 1-place decimals with a total of 1

In a Year 5 mathematics lesson, students are building on their understanding of decimal number pairs that sum up to 1, and extending this knowledge to find decimal pairs that total 10. The lesson introduces a methodical approach to deriving these pairs by separating the ones and the tenths before combining them to make the total. For example, to find a pair that adds up to 10, one might start with 2.4 and 7.6. The process involves adding the whole numbers first (2 + 7 = 9), then adding the decimal parts (0.4 + 0.6 = 1), and finally combining these sums to achieve the total (9 + 1 = 10).

The 'Let's Try It' section encourages students to apply this method independently. They are tasked with adding 6.2 and 3.8 together. Students are guided to first add the whole numbers (6 + 3), then the tenths (0.2 + 0.8), and finally to add these partial sums together to find the total. This approach reinforces the concept of decimal place value and addition. For further practice and reinforcement, students are directed to workbook pages that contain more exercises on deriving decimal pairs with a total of 10, ensuring they have ample opportunity to master this mathematical skill.
