Lesson details
Key learning points
- When solving problems, the column addition and column subtraction algorithms are sometimes the most efficient methods.
- If the numbers have different amounts of digits, ensure the digits are aligned in their appropriate place value columns.
- Identify when regrouping is needed when carrying out column addition and subtraction.
Keywords
Regroup - The process of unitising and exchanging between place values is known as regrouping. For example, 10 tens can be regrouped for one hundred; one hundred can be regrouped for 10 tens.
Common misconception
Mis-align numbers when setting up algorithms if the numbers have different amount of digits. When finding 1 missing part out of 3 parts, children may perform two subtractions, which is inefficient.
When setting up the algorithm, ensure digits in the same place value place are aligned. When finding 1 missing part of 3 parts, first we add the known parts then we subtract from the whole.
