Accurately label a range of number lines

I can label number lines accurately and explain the meaning of each part.

Lesson details

Key learning points

  1. Mixed numbers are numbers that can be located on a number line.
  2. Stem sentence: ‘Each interval on the line is divided into _________ equal parts. ‘This allows us to count in _________.'
  3. The stem sentence support us to determine the unit that we are working with.

Keywords

  • 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 misconception

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.

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.

Practice counting on and back in fractions using the number line to help. You could use a counting stick for counting in tenths.
