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 use knowledge of divisibility rules when the divisor is 2 to solve problems.
Key Notes
- All numbers in the two times table are even.
- All numbers in the two times table are divisible by 2
- If a number is even, it is in the two times table and is divisible by 2
- If a number is odd, it is not divisible by 2 because when divided by 2, it does not give two whole numbers.
Vocabulary To Learn
- Divisible: When a number can be divided into equal parts without any left over, we can say that it is divisible by ___
- Even: Any number that can be divided exactly by 2 is an even number. The last digit is 0, 2, 4, 6 or 8
Common Mistakes To Avoid
- Children may not see 2-digit numbers as divisible by 2 if they are not in their 2 times tables.
3 Quick Questions (With Answers)
1. Solve this in steps: explain the method from this lesson and why each step matters.
All numbers in the two times table are even. All numbers in the two times table are divisible by 2.
2. Use this key word in a maths sentence and explain it clearly. 'Divisible'
When a number can be divided into equal parts without any left over, we can say that it is divisible by ___. 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 not see 2-digit numbers as divisible by 2 if they are not in their 2 times tables. Correction: Encourage children to apply the knowledge that a number is divisible by 2 when it is even. The distinction between even and odd numbers can be revisited prior to the lesson and displayed to reference within the lesson.
