*I can represent proportional relationships by equations, tables, and graphs. *I can verify if two quantities are directly proportional. *I can solve real world problems using equivalent ratios. Opener: Write a letter or note (3 -5 sentences) to another person, character, political figure, etc. telling him/her something you know or think about constant of proportionality.

*I can represent proportional relationships by equations, tables, and graphs. *I can verify if two quantities are directly proportional. *I can solve real world The relationship is NOT problems using proportional because the “rate equivalent ratios. of change” is not constant as the ordered pairs change. It does not go through the origin. The relationship is NOT proportional because the “rate of change” is not constant as the ordered pairs change. It does not go through the origin.
*I can represent proportional relationships by equations, tables, and graphs. *I can verify if two quantities are directly proportional. *I can solve real world problems using equivalent ratios. 28 140 ÷ 5 = 28 words per minute 196 ÷ 7 = 28 words per minute
The rate is not constant *I can represent proportional relationships by equations, tables, and graphs. *I can verify if two quantities are directly proportional. *I can solve real world problems using equivalent ratios. 225 ÷ 9 = 25 pages per hour 192 ÷ 7 = 27. 43 pages per hour
*I can represent proportional relationships by equations, tables, and graphs. *I can verify if two quantities are directly proportional. *I can solve real world problems using equivalent ratios. Y = 4 x is proportional because it is a straight line that goes through the origin. Y = 4 x + 2 is NOT proportional because it does not go through the origin.
