Unit Summary
In this unit pupils will double and halve 2-digit numbers. They will explore division as both grouping and sharing and learn to use times table facts to find the quotient for 2x 5x 10x tables.
Lesson Summary
You will learn to identify the patterns and relationships between the 5 and 10 times tables.
Key Notes
- All multiples of 10 are also multiples of 5
- Multiples of 10 have a ones digit of 0
- Even multiples of 5 have a ones digit of 0, and odd multiples of 5 have a ones digit of 5
- Multiples of 10 are double the value of multiples of 5
- Multiples of 5 are half the value of multiples of 10
Vocabulary To Learn
- Multiple: A multiple is the result of multiplying a number by another whole number.
- Odd: Any integer that cannot be divided exactly by 2
- Even: Any integer that can be divided exactly by 2 is an even number. The last digit is 0, 2, 4, 6 or 8
- Double: To become twice as many / to multiply by two.
- Half: One of two equal parts of a whole. To divide into two equal parts.
Common Mistakes To Avoid
- Children may struggle to recall multiplication facts related to the 5 and 10 times tables.
3 Quick Questions (With Answers)
1. Solve this in steps: explain the method from this lesson and why each step matters.
All multiples of 10 are also multiples of 5. Multiples of 10 have a ones digit of 0.
2. Use this key word in a maths sentence and explain it clearly. 'Multiple'
A multiple is the result of multiplying a number by another whole number. Use this word when showing your method, then check your final answer is reasonable.
3. Spot and fix this common maths mistake.
Mistake: Children may struggle to recall multiplication facts related to the 5 and 10 times tables. Correction: Using times table charts where needed throughout this unit will support children in recalling facts and enable them to focus on seeing the relationships, e.g. between the 5 and 10 times table. These can be used until children become more fluent.
