Lesson details
Key learning points
- When creating problems, we must decide whether we want to create an addition or a subtraction problem.
- Addition problems can involve combining two parts to make the whole.
- Addition problems can also involve increasing one part by the other part to reach the whole.
- Subtraction problems can involve partitioning one part from the whole to find the remaining part.
- Subtraction problems can also involve decreasing the whole by one part to find the remaining part.
Keywords
Addition - Addition involves finding the total, or sum, by combining two or more numbers.
Subtraction - Subtraction involves taking one number away from another.
Bridge 10 - An addition or subtraction strategy where numbers are partitioned to reach the previous or next multiple of 10, so bonds to 10 can be used to calculate more efficiently.
Common misconception

Give criteria, such as the context, the numbers involved, an equation to represent, or a given structure of addition or subtraction to help focus and structure their thoughts.
