Unit Summary
In this unit pupils will represent numbers 6 - 10 by partitioning in different ways. They will learn what odd and even numbers are and how they can be partitioned. They will identify a missing part when a whole is partitioned into two parts where one of the parts is known.
Lesson Summary
You will learn to explain what odd and even numbers are and the difference between them.
Key Notes
- Odd and even numbers alternate.
- Between two even numbers there is an odd number.
- Between two odd numbers there is an even number.
- Identify odd and even numbers using both the number names and numerals.
Vocabulary To Learn
- Odd: Any number that cannot be divided exactly by 2. The last digit is 1, 3, 5, 7 or 9.
- Even: Any number that can be divided exactly by 2. The last digit is 0, 2, 4, 6 or 8.
Common Mistakes To Avoid
- Children may see the pairs in an odd number and think it is an even number.
3 Quick Questions (With Answers)
1. Solve this in steps: explain the method from this lesson and why each step matters.
Odd and even numbers alternate. Between two even numbers there is an odd number.
2. Use this key word in a maths sentence and explain it clearly. 'Odd'
Any number that cannot be divided exactly by 2. The last digit is 1, 3, 5, 7 or 9. 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 see the pairs in an odd number and think it is an even number. Correction: Ensure children are looking for the extra one that makes a number odd. Provide opportunities to group other odd sets e.g. pairs of socks, pairs of hands / feet and realising an odd number always has an 'odd' one.
