# Max Maths, Year 3, Try it, Subtracting 1-digit numbers from 3-digit numbers with regrouping (2)

In a practical application of subtraction for Year 3 students, Max Maths introduces an everyday scenario: a supermarket with 440 parking spaces has only 5 cars parked early in the morning. The task is to determine how many parking spaces are still available. Students are encouraged to use counting blocks to visually represent the parking spaces and then subtract the occupied spaces from the total. By removing the blocks that represent the 5 parked cars from the total of 440, students can easily see how many blocks—and consequently, parking spaces—remain available.

The 'Let's Practise' section provides further exercises to reinforce the concept of subtracting one-digit numbers from three-digit numbers with regrouping. For example, Tya has a book with 362 pages and reads 6 pages in one sitting; students must calculate the remaining pages. Other real-life scenarios include a farmer with 622 seeds where 8 have flowered, requiring students to find out how many are yet to flower, and a growth measurement where Toby has grown by 6 centimetres and is now 123 centimetres tall, prompting students to work out his height from the previous year. Additional practice is provided with a series of subtraction problems, ranging from 583 minus 6 to 185 minus 7, helping to solidify the students' understanding and proficiency in the subtraction process. The workbook pages 64 to 65 are referenced for further practice and consolidation of these skills.
