Represent addition and subtraction facts within 10
Lesson details
Learning outcome
I can represent addition and subtraction facts within 10
Key learning points
- Representing a problem can help us to find addition and subtraction facts.
- In addition, we can change the order of the addends and the sum will remain the same.
- We can use addition facts to help us find subtraction facts.
- If I know 3 + 2 = 5, I know that 5 - 2 = 3
Keywords
Add - To find the total, or sum, by combining two or more parts (addends), or to increase an amount by adding another.
Subtract - To partition one part from another (the subtrahend from the difference), or to decrease an amount by taking an amount away.
Represent - To communicate mathematical ideas through models.
Common misconception
Without correct representation, children may struggle to know what to calculate.
If needed, provide support at this stage so that the structure of the mathematics is clear to children.
Teacher tip
Multiple strategies to derive facts are spoken about within this lesson but will be focused on throughout the unit. The use of games can be used to reinforce the recall of addition and subtraction facts. The slide decks are as a scaffold to prompt games and are not to be seen as a complete lesson.
