Max Maths, Year 3, Work Book, Subtraction of 1-digit numbers from 3-digit numbers with and without regrouping

The Max Maths workbook for Year 3 includes a section dedicated to the subtraction of 1-digit numbers from 3-digit numbers, with exercises both with and without the need for regrouping. In Practice 2, students are first instructed to visually subtract by crossing out blocks that represent units, tens, and hundreds, and then counting what remains to find the answer. For example, they would subtract 2 from 253 and 3 from 485, observing the process of simple subtraction without regrouping.

Further activities require pupils to complete subtractions by writing out the sums and finding the results. They are presented with a series of three-digit numbers from which they must subtract 1-digit numbers, such as subtracting 1 from 564, 6 from 738, and so on. The workbook then introduces the concept of regrouping, where students learn to exchange one ten for ten ones to facilitate subtraction when the number of ones in the original number is not sufficient. This is illustrated through examples such as subtracting 6 from 523, where regrouping is necessary. The students are guided through the process with clear steps, reinforcing their understanding of the relationship between ones and tens in subtraction.
