1. Read this first

   Use this

   Three tables (hours | miles). Table A: 1 | 5; 2 | 8; 3 | 11. Table B: 2 | 6; 5 | 15; 8 | 24. Table C: 2 | 10; 4 | 20; 6 | 26.

2. 1.

   Tala tests three walking routes. Each table shows hours and miles. Which table is proportional?

   • Table A
   • Table C
   • Table B

3. Use this

   Three tables (minutes | pages). Table A: 1 | 4; 2 | 8; 3 | 13. Table B: 2 | 7; 4 | 9; 6 | 11. Table C: 3 | 12; 6 | 24; 9 | 36.

4. 2.

   Esme checks three printers. Each table shows minutes and pages. Which table is proportional?

   • Table B
   • Table C
   • Table A

5. Use this

   Three tables (days | inches). Table A: 4 | 6; 6 | 9; 10 | 15. Table B: 2 | 3; 4 | 6; 8 | 13. Table C: 2 | 3; 4 | 5; 6 | 7.

6. 3.

   Kira measures three plants. Each table shows days and inches. Which table is proportional?

   • Table B
   • Table A
   • Table C
7. 4.

   Bo's sunflower seedling was already tall when the measuring began. The graph shows days and inches, but only part of the graph. Is it proportional, and why?

   • Yes: both points have y bigger than x
   • No: the amount for 1 is 5/2 at one point and 3/2 at the other
   • Yes: it is a straight line
8. 5.

   Luz hikes a trail that starts away from the gate. The graph shows hours and miles, but only part of the graph. Is it proportional, and why?

   • No: the amount for 1 is 3 at one point and 12/5 at the other
   • Yes: it is a straight line
   • Yes: both points have y bigger than x
9. 6.

   Milo rolls a ball down a ramp and marks where it is each second. The graph shows seconds and feet. Is it proportional, and why?

   • No: not a straight line (2 feet for 1 second at one point, 4 at another)
   • No: it goes up too fast
   • Yes: it goes through (0, 0), and starting there is enough to make it proportional
10. 7.

    Ari rolls a toy car down a ramp, and it speeds up. The graph shows seconds and feet. Is it proportional, and why?

    • No: not a straight line (1/2 foot for 1 second at one point, 1 at another)
    • No: it goes up too fast
    • Yes: it goes through (0, 0)
11. 8.

    Pia slides a sled down a snowy hill that gets steeper. The graph shows seconds and feet. Is it proportional, and why?

    • No: it goes up too fast
    • No: not a straight line (3 feet for 1 second at one point, 6 at another)
    • Yes: it goes through (0, 0)

12. Use the table

    cups of flour	cups of butter
    1/4	1/6
    1/2	1/3
    3/4	1/2

13. 9.

    Noah tests a shortbread recipe, one very crumbly batch at a time. The table shows cups of flour and cups of butter. Is it proportional, and why?

    • No: cups of flour and cups of butter are different numbers
    • No: cups of butter go up by 1/6 each time, but cups of flour go up by 1/4
    • Yes: every row has 2/3 cup of butter for 1 cup of flour
14. 10.

    Ren stirs oatmeal for a hiking trip, and the last batch gets extra. The table shows cups of oats and cups of milk. Is it proportional, and why?

    • Yes: rows one and two both have 1/2 cup of milk for 1 cup of oats
    • Yes: cups of oats and cups of milk both get bigger
    • No: row three has 2/3 cup of milk for 1 cup of oats, not 1/2
