# Max Maths, Year 3, Practice, Subtracting 1-digit numbers from 3-digit numbers with regrouping (1)

In Max Maths for Year 3, students practice the skill of subtracting 1-digit numbers from 3-digit numbers, an essential arithmetic operation that also introduces the concept of regrouping. One practical application presented is a scenario involving a supermarket car park with 440 spaces, where only 5 are occupied early in the morning. Students are asked to calculate the number of available spaces using counting blocks as a visual aid, reinforcing their understanding of subtraction in a real-world context.

The practice section, titled 'Let's Practise', includes a variety of subtraction problems aimed at helping students consolidate their skills. For instance, they are tasked with figuring out how many pages Tya has left to read after starting a book with 362 pages and reading 6. In another problem, they calculate the number of seeds yet to flower after a farmer plants 622 seeds and 8 of them flower. Additional exercises involve determining Toby's height a year ago based on his current height and growth, as well as a series of straightforward subtraction problems with varying 3-digit numbers. These exercises not only improve the students' numerical fluency but also their ability to apply mathematical concepts to everyday situations. For further practice, students are directed to workbook pages 64 to 65.
