DescriptionIn the fourth of five clips from a single class session, we see two students, Jessica and Andrew, placing unit fractions, ranging from 1/10 to 1/2, on a number line segment with endpoints labelled 0 and 1. They conjectured about the location for the point 1/100 and whether the magnitude of the number line makes a difference in the placement of these numbers. The question of a possible location for 1/1000 on the number line is addressed by Eric. Andrew and Jessica then place 3/4 on the number line based on their estimation for the location of 1/2, They explain to a researcher why they located 1/3 at two different points on their number line as well as how and why they positioned 1/100.
Problem Statement: Working with your partner, place the unit fractions from 1/10 to 1/2 on a number line segment that goes from 0 to 1. Where would you place 1/100 and 1/1000 on this number line?
