Lesson Summary
You will learn to solve problems using knowledge and strategies to add 5 and 3 and 6 and 3.
Key Notes
- Addition and subtraction facts for the pairs 5 and 3 and 6 and 3 can be related to known facts and strategies.
- 5 and 3 can be calculated using the five and a bit context.
- 6 and 3 can be calculated by relating it to 6 + 4 = 10 which is a known fact.
Vocabulary To Learn
- Strategies: A plan of action designed to achieve an aim.
Common Mistakes To Avoid
- With these particular facts, children may resort to counting on in ones from five or six and you want to avoid this.
3 Quick Questions (With Answers)
1. Solve this in steps: explain the method from this lesson and why each step matters.
Addition and subtraction facts for the pairs 5 and 3 and 6 and 3 can be related to known facts and strategies. 5 and 3 can be calculated using the five and a bit context.
2. Use this key word in a maths sentence and explain it clearly. 'Strategies'
A plan of action designed to achieve an aim. Use this word when showing your method, then check your final answer is reasonable.
3. Spot and fix this common maths mistake.
Mistake: With these particular facts, children may resort to counting on in ones from five or six and you want to avoid this. Correction: Begin by linking 5 + 3 in the context of 'five and a bit' to the explicit knowledge that 5 + 3 = 8 With 6 + 3, stress that this can easily be related to 6 + 4 which is a known fact. Encourage pupils to use one hand to represent 5 without counting.
