Max Maths, Year 4, Work Book, Subtracting 2- and 3-digit numbers using counting blocks and column method

In 'Max Maths Year 4 Workbook', students are encouraged to develop their subtraction skills through a series of engaging and educational exercises. Practice 7 focuses on subtracting 2- and 3-digit numbers using two distinct methods: counting blocks and the column method. The first activity requires students to visually understand subtraction by crossing out counting blocks that represent the numbers being subtracted and then counting the blocks that remain. For example, students would subtract 12 from 253 by removing blocks representing the number 12 and counting what's left to find the answer.

The workbook then progresses to the column method, a more traditional approach to subtraction. Students are asked to subtract numbers such as 564 minus 51 by aligning the digits in columns according to their place value and subtracting each column starting from the ones place, carrying over when necessary. Additionally, the workbook includes exercises designed to reinforce the concept of regrouping. Students fill in missing numbers to complete each step of the subtraction process, which helps them to understand the mechanics of borrowing from the tens and hundreds places when subtracting larger numbers. By the end of Practice 7, students will have practiced a variety of subtraction problems, enhancing their numerical fluency and problem-solving skills.
