TIMS Task

Students will need a copy of the Centimeter Graph Paper.

1. No, for two of the points, Michael plotted the first number in the ordered pair on the vertical axis, instead of the horizontal axis.
2. 
3. Possible responses: The points form a line; in each ordered pair, the second number is double the first number.

Ongoing Assessment

Use DPP item X to assess making point graphs using ordered pairs [E5].

X. Points on a Graph

Michael made a point graph from a list of ordered pairs Mrs. Dewey wrote on the board.

1. Did Michael plot the points correctly? Use his point graph to explain your answer.
2. If you think Michael drew the graph incorrectly, plot the points correctly on a separate sheet of Centimeter Graph Paper.
3. What patterns do you notice in the data on the correct point graph?
