Whenever I teach fractions, I find that students have the most difficulty drawing accurate number lines...and they are expected to draw them over and over...and over again!
Here is a basic printable which includes nine number lines (one each for halves, thirds, fourths, fifths, sixths, sevenths, eighths, ninths, and tenths). Each number line is labeled from 0 to 1. Measurements are accurate so students can practice noticing patterns between unit fractions, equivalent fractions, etc.
