Use two brown rods to represent the two
holes.
Each hole can then be partitioned into four equal parts, using the red rods, to represent fourths.
A line can then be drawn on the number line to represent the distance from 0 to 3/4 .
Think about how you can add 5/8 to 3/4.
If the number line is partitioned into fourths, how can you also partition it into
eighths?
