Unit Summary
In this unit pupils will compose and decompose quantities made of whole numbers and fractional parts.
Lesson Summary
You will learn to label number lines accurately and explain the meaning of each part.
Key Notes
- Mixed numbers are numbers that can be located on a number line.
- Stem sentence: 'Each interval on the line is divided into _________ equal parts. 'This allows us to count in _________.'
- The stem sentence support us to determine the unit that we are working with.
Vocabulary To Learn
- Mixed number: A mixed number is a whole number and a fraction combined into one "mixed" number. For example: one and a half is a mixed number.
- Interval: An interval is the space between two values or points.
Common Mistakes To Avoid
- Children may write 'four-quarters' instead of 'one' or 'one and eight-eighths' instead of '2'. Children may also confuse 'part' and 'marks' when determining the unit that we are working with.
3 Quick Questions (With Answers)
1. Solve this in steps: explain the method from this lesson and why each step matters.
Mixed numbers are numbers that can be located on a number line. Stem sentence: 'Each interval on the line is divided into _________ equal parts. 'This allows us to count in _________.'.
2. Use this key word in a maths sentence and explain it clearly. 'Mixed number'
A mixed number is a whole number and a fraction combined into one "mixed" number. For example: one and a half is a mixed number. 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 write 'four-quarters' instead of 'one' or 'one and eight-eighths' instead of '2'. Children may also confuse 'part' and 'marks' when determining the unit that we are working with. Correction: One is composed of four-quarters, but we write '1'. Two is composed of one and eight-eighths but we write '2'. We need to count the equal parts in between the intervals, not the marks.
