Study Guides
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 twos going forwards and backwards and notice the pattern in the count.
Key Notes
- When counting forwards in twos, the ones digit follows the pattern 0, 2, 4, 6, 8
- When counting backwards in twos, the ones digit follows the pattern 8, 6, 4, 2, 0
- We can use the pattern when counting to help us remember the numbers.
Vocabulary To Learn
- Twos: We can skip count in 'twos', or the multiples of two.
Common Mistakes To Avoid
- Children often miss out 12 when reciting the multiples of two due to the irregularity and not hearing the 'two' in twelve.
3 Quick Questions (With Answers)
1. Solve this in steps: explain the method from this lesson and why each step matters.
When counting forwards in twos, the ones digit follows the pattern 0, 2, 4, 6, 8. When counting backwards in twos, the ones digit follows the pattern 8, 6, 4, 2, 0.
2. Use this key word in a maths sentence and explain it clearly. 'Twos'
We can skip count in 'twos', or the multiples of two. Use this word when showing your method, then check your final answer is reasonable.
3. Spot and fix this common maths mistake.
Mistake: Children often miss out 12 when reciting the multiples of two due to the irregularity and not hearing the 'two' in twelve. Correction: Make deliberate errors around this and use practical objects to show the effect of adding two to ten. Orally rehearse counting in twos, both through and from 10.
