Lesson objective: Measure and draw fractional lengths on number lines and rulers.

This lesson helps to build procedural skill with identifying unit fractions on a number line (and ruler). The partitioning of number lines and rulers are used here to introduce the idea that fractional lengths are invariant. This work develops students' understanding that a length does not change if its position on a number line or ruler changes.

Students engage in Mathematical Practice 5 (use appropriate tools strategically) as they measure and draw fractional lengths on both number lines and rulers.

Key vocabulary:

  • align
  • length
  • number line
  • partition
  • ruler
  • unit
  • unit fraction
