Lesson details
Key learning points

- You can combine the addends to find the sum.
- To find how many objects there are altogether, you must count both addends.
Keywords
Part - A piece or section of the whole.
Whole - All of a group or number.
Altogether - In total, the whole amount.
Common misconception
Children may have difficulty when the sum is presented on the left of the equal sign.
Ensure that equations are arranged with the sum both on the left and the right of equal sign. Use term 'is equal to' to stress equality.
