Max Maths, Year 3, Try it, Adding and subtracting multiples of 10 and 100

In a practical exercise aimed at Year 3 students, children are encouraged to understand the concepts of addition and subtraction with multiples of 10 and 100 through a hands-on approach. The first problem presents a scenario where Han has £168 initially and spends £60 on presents. To solve this, students use counting blocks to visually represent Han's money, with ones, tens, and hundreds clearly separated. After representing the initial amount, students then remove the blocks that equate to the £60 spent, allowing them to see the subtraction process physically and calculate the remaining amount. The exercise reinforces the understanding of place value and the subtraction of multiples of ten.

The second problem further develops these skills by asking students to calculate 586 minus 30. This problem is presented with a visual aid showing the hundreds, tens, and ones as separate groups, which helps students to see the subtraction of 30 as the removal of three tens from the total. By breaking down the numbers into their constituent parts, children can more easily comprehend the subtraction process. The exercise is designed to build confidence in manipulating numbers and to understand the relationship between place values when adding or subtracting. Students are instructed to continue their practice on workbook page 39 to further consolidate their skills.
