Unit Summary
In this unit pupils will represent the 2x 10x table in different ways and use 2x 10x table to solve problems. They will explain the relationship between adjacent multiples of 2/10 and that factor pairs can be written in any order.
Lesson Summary
You will learn to explain the relationship between adjacent multiples of 10.
Key Notes
- Adjacent multiples of 10 have a difference of 10
- If you add 10 to a multiple of 10 you get the next multiple of 10
- If you subtract 10 from a multiple of 10 you get the previous multiple of 10
Vocabulary To Learn
- Previous: Occurring before in time or order.
- Next: Occurring after in time or order.
Common Mistakes To Avoid
- Pupils may not understand the keyword adjacent and have difficulty understanding the word problems.
3 Quick Questions (With Answers)
1. Solve this in steps: explain the method from this lesson and why each step matters.
Adjacent multiples of 10 have a difference of 10. If you add 10 to a multiple of 10 you get the next multiple of 10.
2. Use this key word in a maths sentence and explain it clearly. 'Previous'
Occurring before in time or order. Use this word when showing your method, then check your final answer is reasonable.
3. Spot and fix this common maths mistake.
Mistake: Pupils may not understand the keyword adjacent and have difficulty understanding the word problems. Correction: Model correct usage in a range of contexts including labelling abstract equations and using the term to identify the known elements in worded problems. Take time to show adjacent on number lines connecting to addition and subtraction of equal groups.
