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

The Max Maths workbook for Year 5 includes a comprehensive review on finding pairs of single-place decimals that add up to 1. The practice extends this concept by exploring pairs of decimals that total 10. In Practice 2, students are tasked with adding together ones and tenths to calculate the sum of each given pair of decimals. For instance, in the first question 3.4 and 6.6 are added, where separately the ones (3 and 6) and the tenths (0.4 and 0.6) are summed up to confirm that together they total 10. This exercise includes several examples, such as 5.8 + 7.2 and 9.1 + 0.9, which are designed to reinforce the students' understanding of decimal place value and addition.

Following the addition exercises, students are prompted to make observations about the patterns in the sums, noting that the ones always add up to a certain number and the tenths also sum up to a specific number. The workbook then challenges students to match pairs of numbers that together equal 10, such as pairing 1.4 with 8.6 or 5.5 with 4.5. Additionally, students are given one number in a pair and are required to write the corresponding number that, when added to the given number, equals 10. This activity not only tests their addition skills but also their understanding of the relationship between numbers and the concept of making a whole through decimal values.
