Common Core Standards: 1. M1.F.IF.B.3 For a function that models a relationship between two quantities, interpret key features of graphs and tables in terms of the quantities, and sketch graphs showing key features given a verbal description of the relationship. 2. M1.F.IF.B.5 Calculate and interpret the average rate of change of a function (presented symbolically or as a table) over a specified interval. Estimate the rate of change from a graph. 3. M1.F.IF.C.6 Graph functions expressed symbolically and show key features of the graph, by hand and using technology. 4. M1.F.IF.C.7 Compare properties of two function each represented in a different way (algebraically, graphically, numerically in tables, or by verbal descriptions). 5. M1.F.LE.A.2 Construct linear and exponential functions, including arithmetic and geometric sequences, given a graph, a table, a description of a relationship, or input-output pairs.
Direct Instruction and Practice with Material: a. TSW work in groups of three to complete a series of 5 stations over the course of two lessons to review writing, graphing, and analyzing linear functions. Each station will last 17 minutes. b. *If students finish any station early, extra practice problems are posted in yellow around the room. Students will be directed to automatically work on those problems if finished early.* 1. Station One: Edulastic Graphing i. TSW login to his/her Edulastic account on a student computer. ii. In Edulastic, the students will complete an assignment of graphing lines in various forms using technology
2. Station Two: Desmos Linear Equations Station i. TSW access a series of tasks using Desmos, an online graphing calculator program. ii. Tasks use technology and have students write equations, graph lines, and complete tables using given points, tables, graphs, or equations iii. TSW record his/her answers on the answer sheet as well as enter the items into the computer
3. Station Three: Linear Equations Tasks Station i. TSW complete real-world tasks that involve linear equations. ii. Some problems require students to write equations, interpret parts of equations, evaluate functions, compare equations in different representations, and justify answers
4. Station Four: Teacher Led: Multiple Representations of Linear Functions Station i. TSW complete a series of tasks involving real world scenarios. ii. TSW receive either a description, equation, table, or graph representing a linear model. TSW complete the other three representations that were not given. iii. When graphing, TSW appropriately label and scale graphs to reflect the context of the problem.
Closure/Reflection 1. With about 5-7 minutes remaining, we will review the success criteria for the day. 2. Students will answer 2 questions in a whole group situation to review material.
Assessment Plan Based on Objectives: 1. Informal a. Ask questions and monitor students as they work through the stations in the lesson. Offer feedback and address common mistakes. Ask assessing and advancing questions to determine where students are at and push them to the next level. b. Informally assess students by listening to their discussions with groupmates. 2. Formally a. Students will receive a score for their work on the stations. b. Material will be on the next assessment, as well as comprehensive assessments throughout the year. (>84% for proficiency)
