# 912Algebra_CED_Functions_LessonPlan

A template of the talk frame was used to plan a lesson for algebra students learning about composite functions. Students are given a problem in which they make a weekly salary, plus commission, two functions, and two possible function compositions to represent the commission. The Think section provides the question, along with two additional parts, and the Talk Idea section presents the possible realizations about the functions. Argumentation language is used through the construction of the student solution.

# 912Algebra_CED_LinearFunctions_Worksheet_Construct_Steepness

This activity was used in an Algebra 2 class. It was used at the beginning of the linear functions unit after students learned about slope. Students worked in small groups to determine the steepness of the given segments. The activity was designed with questions that were scaffolded in order to help students dig deeper into their mathematical reasoning. The lesson was also used as a way to get students familiar with showing their “evidence” and supporting their “evidence” with important math ideas, i.e. “warrants”

# 912Algebra_CED_LinearFunctions_LessonPlan

A template of the talk frame was used to plan a lesson for algebra students learning about linear equations. The teacher recorded what he anticipated how students would reword the question in the Think section, what ideas they would contribute in the Talk Ideas section, and both their realization that the problem has multiple solutions and the valid mathematical ideas in the We Understand section. The mathematics focused on modeling with linear equations, creating linear equations from a word problem, and the break-even point. Specifically, students are given the fixed price and price per night of two dog kennels and must determine when the two will be equal.
