Answer for screen readers
The techniques for written addition and subtraction involved in the Year 6 Western Australian Curriculum include methods such as regrouping for addition and borrowing for subtraction.
Steps to Solve
- Identify Addition and Subtraction Techniques
In Year 6, students typically learn to use various methods for addition and subtraction, including regrouping (carrying) for addition and borrowing for subtraction. Start by listing the methods you want to demonstrate.
- Written Addition Method
For a two-digit number addition, write the numbers one under the other, aligned by place value. For example, to add 47 and 36, set it up as follows:
47
+ 36
_____
- Perform the Addition
Begin adding the units (rightmost column) first: $7 + 6 = 13$. Write down 3 and carry over 1 to the tens column.
Then add the tens: $4 + 3 + 1 = 8$.
So, the final addition looks like this:
47
+ 36
_____
83
- Written Subtraction Method
For a two-digit number subtraction, align the numbers similar to addition. For example, to subtract 36 from 47, arrange it as:
47
- 36
_____
- Perform the Subtraction
Start by subtracting the units: $7 - 6 = 1$.
Next, subtract the tens: $4 - 3 = 1$.
Thus, the final subtraction will look like:
47
- 36
_____
11
