Max Maths, Year 2, Learn together, Subtracting tens and hundreds (3)

In a Year 2 mathematics lesson from Max Maths, students learn about subtracting tens from a given number, with a focus on understanding the concept without the use of physical aids like blocks. Tya, a character in the lesson, demonstrates how to subtract tens from the number 78. The first example shows that when you subtract 10 from 78, you get 68, and when you subtract 20, you end up with 58. This visual representation helps to reinforce the idea that when we subtract tens, the ones digit remains unchanged.

The lesson encourages students to practice this method of subtraction by choosing their own numbers and subtracting tens in their notebooks. By crossing out tens, students can easily see the pattern that emerges, which is that the tens digit decreases by one with each subtraction of ten, while the ones digit stays the same. This method simplifies the subtraction process and supports the development of mental arithmetic skills. The pattern recognition aspect of the lesson is an important step in helping students to understand the relationship between numbers and to build a strong foundation for more complex arithmetic operations.
