Unit Summary
In this unit pupils will use representations to identify and explain patterns in powers of 10 and read numbers with up to 7 digits efficiently. They will order and compare numbers with up to 8 digits and calculate with numbers of this scale.
Lesson Summary
You will learn to estimate and identify numbers on number lines.
Key Notes
- Understanding the scale of a number line helps to estimate and identify numbers on it.
- To determine the multiples that the number line increases in, take the whole and divide it by the number of parts.
- Locating the midpoint on a number line or between multiples helps to estimate.
Vocabulary To Learn
- Estimate: When we estimate, we find a value that is close enough to the right answer, usually with some thought or calculation involved.
- Midpoint: The midpoint is the middle of something - in this case the middle of a number line. It is the point halfway along.
Common Mistakes To Avoid
- Children may incorrectly place a number on a number line according to just counting the parts rather than working out the scale.
3 Quick Questions (With Answers)
1. Solve this in steps: explain the method from this lesson and why each step matters.
Understanding the scale of a number line helps to estimate and identify numbers on it. To determine the multiples that the number line increases in, take the whole and divide it by the number of parts.
2. Use this key word in a maths sentence and explain it clearly. 'Estimate'
When we estimate, we find a value that is close enough to the right answer, usually with some thought or calculation involved. 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 incorrectly place a number on a number line according to just counting the parts rather than working out the scale. Correction: Determine the multiples that the number line is increasing in first: find the difference between the given start and end numbers and divide by the number of parts.
