Type: Lesson/Unit Plan

Overview:

In Module 1, Topic A, students explore the main functions that they will work with in Grade 9: linear, quadratic, and exponential. The goal is to introduce students to these functions by having them make graphs of situations (usually based upon time) in which the functions naturally arise (A-CED.2). As they graph, they reason abstractly and quantitatively as they choose and interpret units to solve problems related to the graphs they create (N-Q.1, N-Q.2, N-Q.3).

Content Standard(s):
 Mathematics MA2015 (2016) Grade: 9-12 Algebra I 4 ) Use units as a way to understand problems and to guide the solution of multistep problems; choose and interpret units consistently in formulas; choose and interpret the scale and the origin in graphs and data displays. [N-Q1] Alabama Alternate Achievement Standards AAS Standard: M.AAS.Q.HS.4- Using real world models, express quantities of measurement to the given precision. (limited to measurements of length (inch, 1/2 inch, 1/4 inch), weight (pounds, kilograms (tenth of a unit), volume (cup, 1/2 cup, 1/4 cup, 1/3 cup, liter), temperature (degree), velocity (mph, kmph). Mathematics MA2015 (2016) Grade: 9-12 Algebra I 5 ) Define appropriate quantities for the purpose of descriptive modeling. [N-Q2] Alabama Alternate Achievement Standards AAS Standard: M.AAS.Q.HS.5- Recognize units of weight (ounces, pounds, grams, kilograms), length (inch, foot, mile, centimeter, meter, kilometer), area (square inches in^2, square feet ft^2, square centimeters cm^2, square meters m^2) and capacity (cubic inches in^3, cubic feet ft^3, cubic centimeters cm^3, cubic meters m^3). Mathematics MA2015 (2016) Grade: 9-12 Algebra I 6 ) Choose a level of accuracy appropriate to limitations on measurement when reporting quantities. [N-Q3] Alabama Alternate Achievement Standards AAS Standard: M.AAS.Q.HS.6- Estimate to the nearest 1, 10, and 100 when adding, subtracting, multiplying, or dividing; include units with estimates.
