Max Maths, Year 3, Learn together, Subtracting 1-digit numbers from 3-digit numbers without regrouping

In the Max Maths curriculum for Year 3, students are introduced to the concept of subtracting 1-digit numbers from 3-digit numbers without the need for regrouping. This foundational skill in arithmetic is essential as it lays the groundwork for more complex mathematical operations that students will encounter as they progress in their education. The learning process is interactive and visual, employing counting blocks to represent the numbers involved, making it easier for young learners to grasp the concept of subtraction by physically removing the blocks that correspond to the amount being subtracted.

For example, one of the exercises involves a scenario where Toby has £187 and gives Padma £5. To solve this, students would represent Toby's original amount with counting blocks and then remove five blocks to visualize the subtraction. After the blocks representing £5 are crossed out, 182 blocks remain, indicating that Toby has £182 left. Another exercise asks students to subtract 3 from 375. By removing three blocks from the total, students can see that 372 blocks remain, demonstrating that 375 minus 3 equals 372. This method of using manipulatives like counting blocks is a practical way to help children understand subtraction without regrouping, making the learning experience both engaging and effective.
