This is a set of 36 task cards designed to support Core Standard 7.RP.A.2.A, which has students take quantities from a table and test for proportionality. These cards provide coordinate grids for each data table. Students graph the data points and test to see if they meet two criteria: 1) They must form a straight line, and 2) The line, when extended, must pass through the origin (0,0). The coordinate grid is shown both on each task card, and duplicated on the student recording sheet.
