Fractions on a Number Line - Obstacle Course Task

This task requires students to use their knowledge of fractions to place obstacles on the correct location on an obstacle course. Students must partition the number line using a ruler to help them. Students will realize that some fractions may be on the same point on a number line. This task requires students bring in their knowledge of measurement, multiplication, and division as well as fractions. (Note: Use calculator tape or other 6 foot long material as the obstacle course / number line.)

Aligned with these standards:

3.NF.2
Represent a fraction 1/b on a number line diagram by defining the interval from 0 to 1 as the whole and partitioning it into b equal parts. Recognize that each part has size 1/b and that the endpoint of the part based at 0 locates the number 1/b on the number line.

Represent a fraction a/b on a number line diagram by marking off a lengths 1/b from 0. Recognize that the resulting interval has size a/b and that its endpoint locates the number a/b on the number line.

3.NF.3
Understand two fractions as equivalent (equal) if they are the same size, or the same point on a number line.
