Max Maths, Year 4, Learn together, Subtracting 2- and 3-digit numbers using counting blocks and column method (3)

In a Year 4 mathematics lesson from Max Maths, students are learning to subtract two- and three-digit numbers using both counting blocks and the column method. The example provided demonstrates how to subtract 324 from 568. The process begins with subtracting the ones. By taking 4 ones from 8 ones, students are left with 4 ones. This is the first step in the column method, where they write the number 4 under the ones column.

The second step involves subtracting the tens. The students subtract 2 tens from 6 tens, resulting in 4 tens, which they then place under the tens column. Finally, they subtract the hundreds. By taking away 3 hundreds from 5 hundreds, they end up with 2 hundreds, which is placed under the hundreds column. After completing all three steps, the students find that 568 minus 324 equals 244. The answer is neatly laid out in the column method format, with 4 in the ones place, 4 in the tens place, and 2 in the hundreds place, reinforcing the concept of place value and the subtraction operation.
