Task# Comparing Decimals on the Number Line

Illustrative MathematicsVaries

This task involves using number lines to compare decimal numbers. The numbers selected in this task are purposefully chosen to target student misconceptions. For example, when asked to compare 0.13 and 0.031, students who are not yet proficient in decimal applications of our base ten system may rush to say that 0.031 is greater than 0.13 because 31 is greater than 13. This task also challenges students to think carefully about the value of each digit and how that affects the number's placement on the number line.
