Analyzing Linear Functions

Algebra I

» Unit:

Graphing Linear Functions

Big Idea:Students analyze different components of slope-intercept form and use their observations to prove statements about lines and points.

Super Mario's (almost) Linear World

8th Grade Math

» Unit:

Linear Regression

Big Idea:We can apply our understanding of linear functions to model things that are almost linear.

Solving Systems by Graphing

Algebra I

» Unit:

Systems of Equations

Big Idea:As students gain confidence in graphing - and interpreting the intersection points on - systems of equations, we continue to see how this skill relates to guess and check.

Scatterplots and Non-Linear Data

Algebra I

» Unit:

Modeling With Statistics

Big Idea:In this lesson students discover that some bivariate data should not be modeled by linear functions. Other functions are considered.

Got Ups? A Statistics Unit Task

Algebra I

» Unit:

Modeling With Statistics

Big Idea:Students are able to demonstrate all that they have learned throughout the statistics unit in this open-ended performance task.

Least Squares Regression and Interpreting Linear Models

12th Grade Math

» Unit:

Statistics: Bivariate Data

Big Idea:Which is the predictor variable and which is the response variable? An interpretation of the results of two regression models will usually make it clear.

From Graphing to Substitution

Algebra I

» Unit:

Systems of Equations

Big Idea:It’s amazing to get to the point where students truly understand how useful and beautiful algebra can be. Transitioning from graphing systems to solving by substitution is an opportunity to get kids there.

Graphing Linear Functions in Standard Form (Day 1 of 2)

Algebra I

» Unit:

Graphing Linear Functions

Big Idea:Students will analyze the importance of intercepts in linear function, and use them to graph lines that are in an unfamiliar format.

Predicting the Height of a Criminal (Day 1 of 2)

Algebra I

» Unit:

Linear Functions

Big Idea:The fun part of this lesson is to introduce to students that the femur length of a person is directly proportional to their height.

Slope & Rate of Change

Algebra I

» Unit:

Linear & Absolute Value Functions

Big Idea:Students will interpret the rate of change in the context of a problem, and use it to make predications about a situation that shows linear growth.

Graphing Linear Functions (Day 1 of 2)

Algebra I

» Unit:

Linear & Absolute Value Functions

Big Idea:Students will apply their knowledge of linear growth to graph a line on a coordinate plane.

Graphing Linear Functions (Day 2 of 2)

Algebra I

» Unit:

Linear & Absolute Value Functions

Big Idea:Students will apply their knowledge of linear growth to graph a line on a coordinate plane.

Our City Statistics Project and Assessment

Algebra I

» Unit:

Our City Statistics: Who We Are and Where We are Going

Big Idea:Students demonstrate interpersonal and data literacy skills as use statistics to learn about their community.

Graphing Linear Functions in Standard Form (Day 2 of 2)

Algebra I

» Unit:

Graphing Linear Functions

Big Idea:Students will use their knowledge of literal equations to rearrange a line in standard form into a familiar format.

HSS-ID.C.7

Interpret the slope (rate of change) and the intercept (constant term) of a linear model in the context of the data.*

HSS-ID.C.8

Compute (using technology) and interpret the correlation coefficient of a linear fit.*

HSS-ID.C.9

Distinguish between correlation and causation.*
