Print Lesson


SWBAT interpret the rate of change (slope) and intercept for various contexts modeled by linear functions.

Big Idea

Students will apply their understanding of slope and intercepts to model different contexts with linear functions!

Entry Ticket

15 minutes

Student will complete the Entry Ticket: Interpreting Rate of Change and Intercepts of Linear Models where they have to compute and interpret the slope and intercepts to a graph of a linear model. This entry ticket is designed to activate student’s prior knowledge on calculating and interpreting slope and intercept for linear functions and equations.  

Academic Vocabulary:


Rate of Change



Linear Model

*Note: place academic vocabulary on word wall as a strategy to assist students in learning academic vocabulary. 


Explicit Instruction and Active Note-taking

30 minutes

After the entry ticket, I will present the PowePoint Slides: Interpreting Rate of Change and Intercepts for Linear Models. This lecture addresses computing and interpreting the rate of change (slope) and intercepts for different scenarios that can be modeled using linear functions.


Collaborative Work and/or Exit Ticket: Interpreting Linear Models

15 minutes

To wrap up work on interpreting the rate of change and intercept for linear models students work on the Exit Ticket: Interpreting Linear Models assignment to show their understanding of the day's main learning objectives. 

This activity can be utilized by the teacher in a number of ways. Students can work on the Exit Ticket as a collaborative activity where they work in groups. Alternatively, the Exit Ticket can be used as a formative assessment where students complete the assignment independently.

Our City Statistics Project Interpreting the Data

30 minutes

To conclude today's lesson I have students work in groups on their collaborative project: Our City Statistics Project Overview
