Use a 'First, then, then, now' story to add three addends
Lesson details
Learning outcome
I can use a 'First, then, then, now' story to add three addends.
Key learning points
- A 'First … then … then … now' story can represent an addition with three addends.
- The addition of three addends can be represented as three different objects on a ten frame.
- The addition of three addends can be represented as three steps on a number line.
- The addition of three addends can be represented as an equation.
Keywords
Addends - Any of the numbers that are added together.
First - Before anything else.
Then - After something in time.
Now - At the present time.
Common misconception
Children may not be able to accurately represent the story as an equation.
Ensure that children are able to say what each number represents in a given equation using the story as a scaffold before asking them to write their own equations to represent ‘First, then, then, now’ stories.
Teacher tip
Represent augmentation on a number line, clearly demonstrating the two increases in quantity. This representation will prepare children for bridging through ten, covered later.
