Max Maths, Year 6, Learn together, Review of pairs of 1-place decimals totalling 10

In the Max Maths Year 6 curriculum, students revisit the concept of decimal pairs that add up to 10. This review is an important exercise in reinforcing their understanding of decimal place values and addition. The lesson encourages students to draw parallels between whole number pairs that total 100 and their decimal counterparts that sum to 10. For example, just as 32 and 68 combine to make 100, the decimal numbers 3.2 and 6.8 work together to reach a total of 10. This connection between whole numbers and decimals is a key learning point, aiding in the retention of the concept.

The practice activity involves completing a table where students fill in the missing decimal numbers to make the sums equal to 10. For instance, they are given one part of the pair, such as 1.7, and they must determine that 8.3 is the missing number to complete the pair (1.7 + 8.3 = 10). This exercise not only helps students to become more familiar with decimal numbers but also enhances their mental arithmetic skills. The lesson provides examples to illustrate the method, such as knowing that 19 and 81 total 100 helps to understand that 1.9 and 8.1 will total 10. This methodical approach to learning decimal pairs is designed to build confidence and proficiency in working with decimal numbers.
