# Max Maths, Year 2, Learn together, Subtraction within 100 (2)

## Maths Resource Description

In a practical subtraction lesson from 'Max Maths, Year 2', children learn how to handle subtraction within 100 using a real-world scenario. Samir starts with $72 and spends $19 on a T-shirt at the market. The task for the students is to figure out how much money Samir will have left after this purchase. To make the concept more tangible, the money is represented as blocks, with each block symbolising a single unit of currency.

The lesson demonstrates that to subtract $19 from $72, we first look at the ones place. However, since we cannot subtract 9 ones from 2 ones, we need to regroup. This involves taking one block of ten and breaking it down into 10 individual ones. With this regrouping, students can now easily subtract 1 ten and 9 ones from $72. After crossing out the appropriate number of blocks, it is revealed that Samir has 53 blocks, or dollars, remaining. The lesson concludes with the confirmation that Samir has $53 left after his purchase. Students are then directed to continue their practice on workbook pages 47 to 48 to reinforce their understanding of subtraction within 100.
