Part 1: Use a twelfths fraction bar to draw a number line and partition it into 12 lengths. Label the tic marks for 0, 1 and the fractions from 0/12 to 12/12. Find strategies to use a halves bar, a fourths bar, and an eighths bar to precisely place equivalent fractions on the same number line. everyone’s number lines the middle” before going to Part 2. “in Part 2: Make a second number line with the twelfths bar. Find strategies to precisely place the equivalent fractions for thirds, sixths and halves on this line. Part 3: Draw a third number line using a tenths fraction bar. Precisely place equivalent halves and fifths on the line with the tenths.
