Draw a horizontal line on a blank sheet of paper to depict the x-axis. Design a vertical line that intersects the x-axis' left end to depict the y-axis.
Measure 1/4 increments along the x-axis and y-axis and mark them with dots. On the x-axis dots, enter the mixed fraction table's items; on the y-axis dots, enter integers in ascending order. For example, next to the first dot from the bottom write "1," next to the second dot from the bottom write "2" and so forth. The number of dots on the y-axis must equal the largest mixed fraction's integer plus 1. For instance, if your largest mixed fraction is 8-1/2, then mark nine dots on the y-axis.
Draw horizontal lines starting from each y-axis dot with a pencil. Design one vertical rectangle for each item at a time, starting from the x-axis and ending on the horizontal line that represents the integer of the item's mixed fraction. For example, if the item has a value of 5-1/4, then it should reach the fifth horizontal line.
Divide the section above the vertical rectangle's top in as many horizontal subsections as the mixed fraction's denominator, using a pencil. On the above example -- the item with a value of 5-1/4 -- divide the space between the fifth and the sixth line in four horizontal subsections.
Extend the rectangle up to the top of the first section to complete the 5-1/4 item's bar. As denominators between mixed fractions vary (5-1/4, 3-1/7, 2-2/3), you must erase the horizontal subsections every time you complete an individual bar.
