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 compare two numbers and say which is greater than or less than the other.
Key Notes
- Numbers can be represented as numerals or using representations.
- Numbers can be compared to see which one is larger or smaller.
- The equality and inequality symbols < > and = can be used to show which number is larger or smaller.
- The 5 and a bit structure can be used to compare by comparing the additional 'bit'.
Vocabulary To Learn
- Compare: You compare to find out what is the same and what is different and compare numbers to find out if one is greater than or less than another.
- More than: More than means having a larger amount of objects in a set than another set.
- Greater than: Greater than means a number has a larger value than another number.
- Fewer than: Fewer than means having a smaller amount in a set than another set.
- Less than: Less than means a number has a smaller value than another number.
Common Mistakes To Avoid
- Children may confuse the inequality symbols and use them the incorrect way around.
3 Quick Questions (With Answers)
1. Solve this in steps: explain the method from this lesson and why each step matters.
Numbers can be represented as numerals or using representations. Numbers can be compared to see which one is larger or smaller.
2. Use this key word in a maths sentence and explain it clearly. 'Compare'
You compare to find out what is the same and what is different and compare numbers to find out if one is greater than or less than another. 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 confuse the inequality symbols and use them the incorrect way around. Correction: Take time to practise using the symbols with hand signals or using manipulatives. Emphasise the shape of the symbols reflecting their use i.e. more cubes 'fit' into the wider end of the symbol.
