Max Maths, Year 3, Learn together, Adding and subtracting multiples of 10 and 100 (1)

In a Year 3 maths lesson, students are introduced to the concept of adding and subtracting multiples of 10 and 100. The lesson begins with a simple and engaging task: adding 10 to 500. By incrementally adding 10 to the number 500, students can visually see the number increase in a sequence: 510, 520, 530, and so on. This exercise helps children to understand the pattern that emerges when adding multiples of 10, reinforcing their grasp of place value and mental arithmetic skills.

The lesson then transitions to subtraction, where students are challenged to subtract 40 from 262. To make this concept tangible, the teaching material suggests using visual aids such as orange beads representing tens. By removing four sets of ten beads from the tens column, students can easily see the result of the subtraction, which in this case is 222. This hands-on approach not only helps students to visualise the subtraction process but also solidifies their understanding of how numbers are composed and decomposed in the context of place value.
