This pupil-friendly study guide includes a unit summary, clear notes, common mistakes, and quick questions with answers.
Unit Summary
In this unit pupils will count efficiently in groups of 2 5 10. They will recognise and explain the value of 1p 2p 5p 10p coins and how a single coin can be worth several pennies. 
Lesson Summary
You will learn to skip count in fives going forwards and backwards, and notice the pattern in the count.
Key Notes
- When counting in fives, each number ends in either 0 or 5
- Each time there is an even number of fives, they fit together to makes a ten.
- The pattern when counting can be used to help us remember the numbers.
Vocabulary To Learn
- Fives: We can skip count in 'fives', or the multiples of five.
- Decade number: These are the multiples of ten which mark the tens boundary where the pattern of counting changes.
Common Mistakes To Avoid
- When counting in fives, children may revert to the pattern of counting in tens after reciting a decade number.
3 Quick Questions (With Answers)
1. Solve this in steps: explain the method from this lesson and why each step matters.
When counting in fives, each number ends in either 0 or 5. Each time there is an even number of fives, they fit together to makes a ten.
2. Use this key word in a maths sentence and explain it clearly. 'Fives'
We can skip count in 'fives', or the multiples of five. Use this word when showing your method, then check your final answer is reasonable.
3. Spot and fix this common maths mistake.
Mistake: When counting in fives, children may revert to the pattern of counting in tens after reciting a decade number. Correction: Use practical equipment such as ten frames and base ten number boards to highlight why the next number in our count could not be a decade number. Explore the pattern in the digits and display these in the environment to promote further discussion.
