6 | 7.RP.A.1 | Compute unit rates associated with ratios of fractions, including ratios of lengths, areas and other quantities measured in like or different units. For example, if a person walks 1/2 mile in each 1/4 hour, compute the unit rate as the complex fraction 1/2/1/4 miles per hour, equivalently 2 miles per hour. | ||||||

9 | 7.RP.A.2 | Recognize and represent proportional relationships between quantities | ||||||

10 | 7.RP.A.2a | Decide whether two quantities are in a proportional relationship, e.g., by testing for equivalent ratios in a table or graphing on a coordinate plane and observing whether the graph is a straight line through the origin. | ||||||

11 | Proportion and Non proportion situation concept lesson | http://map.mathshell.org/materials/download.php?fileid=1455 | ||||||

12 | 7.RP.A.2b | Identify the constant of proportionality (unit rate) in tables, graphs, equations, diagrams, and verbal descriptions of proportional relationships. | ||||||

13 | Walking Rates | NCTM: Navigating Through Algebra | Excellent approach to generate linear proportions/equations, then extrapolate to make predictions with change of units | |||||

14 | Circumference vs Diameter | Explore their relationship by measuring several round objects, recording these in tables, then graphing on a coordinate plane. Students explain what ordered pair means, and then define Pi in their own words | Extend by predicting (estimating) additional C or D's | |||||

15 | Determine the Thickness of a Sheet of Paper | Need caliper rulers and scissors. Provide a sheet of paper to each student, cut it in half, then regroup and cut in half again, iterate this process 6 times. All along students attempt to measure the aggregate thickness. Organize data in a table and graph on a coordinate plane. Express answer in both cm and mm. | This could be a follow up to the previous activity for independent/group practice. | |||||

16 | 7.RP.A.2c | Represent proportional relationships by equations. For example, if total cost t is proportional to the number n of items purchased at a constant price p, the relationship between the total cost and the number of items can be expressed as t = pn. | ||||||

17 | ||||||||

18 | ||||||||

19 | 7.RP.A.2d | Explain what a point (x, y) on the graph of a proportional relationship means in terms of the situation, with special attention to the points (0, 0) and (1, r) where r is the unit rate. | ||||||

20 | ||||||||

21 | ||||||||

22 | 7.RP.A.3 | Use proportional relationships to solve multistep ratio and percent problems. Examples: simple interest, tax, markups and markdowns, gratuities and commissions, fees, percent increase and decrease, percent error. | ||||||
