#### Peaches and Plums

According to the resource graph, which costs more: peaches or plums? Algebra learners compare two proportional relationships and then throw in a banana. Leaving out the scale helps students become intuitive about graphing.

Lesson Planet

#### Find the Change

This exercise is an opportunity for algebra learners to understand the connection between the slope of a line and points found on the line. Use similar triangles to explain why slope m is the same between any two points. Discuss with the...

Lesson Planet

#### DVD Profits, Variation 1

The idea in the resource is to understand the connections between proportional relationships, lines, and linear equations. To stay within the context of the standard, skip the part of the resource that solves with unit rates. Instead,...

Lesson Planet

#### Proportional Relationships, Lines, and Linear Equations

The resource is a good introduction to what makes a proportional relationship between two lines. Discuss the similarities of both lines and the possibility of intersection. Use this opportunity to list other acceptable forms of each...

Lesson Planet

#### Comparing Speeds in Graphs and Equations

Compare two different proportional relationships on a graph. It is up to your mathematicians to determine which of two moving objects have greater speed. A good example of a Common Core multiple choice question.

Lesson Planet

#### Coffee by the Pound

This is a great exercise in graphing proportional quantities to interpret the unit rate as the slope of a graph. It is not easy for learners to understand what a unit rate is. When it is presented as the slope of a linear line graph,...

Lesson Planet

#### Who Has the Best Job?

Making money is important to teenagers. It is up to your apprentices to determine how much two wage earners make with their after school jobs. Participants work with a table, an equation, and a graph and compare the two workers to see...

Lesson Planet

#### Sore Throats, Variation 2

What does math have to do with a sore throat? When you mix water and salt you have a great review of how to represent proportional relationships by an equation or graph. Here the proportions of the mixtures may be different, but the...

Lesson Planet

#### Four Activities Using Straight Line Graphs

This math packet includes four different activities which puts linear equations and line of best fit in the context of real world applications. Each activity uses a different linear math modeling equation and asks the learners to...

Lesson Planet

#### Creating Linear Models for Data 3

Scholars solve 24 various types of problems that include defining Hooke's Law, conducting an experiment, and exploring rate of change. They create a scatter plot to show the data for the number and the distance from the table to the top....

Lesson Planet

#### Floating Pennies

How many pennies can you put in a can before it sinks? Learners experiment until they discover how many pennies will sink the can. They represent the data on a graph and determine how to use the graphic representation to make predictions...

Lesson Planet

#### Beginning Rates of Change

Giddayup! How can we represent how far a horse can trot within a certain amount of time? Show it on a graph! After examining this example, math classes crate their own "stories" for different tables of time and distance data, and then...

Lesson Planet

#### Human Slope

Middle and high schoolers explore the concept of slope. In this slope activity, learners graph lines using a life-size graph. They use chalk on a blacktop to create a coordinate plane and use each other as the tick marks on the grid....

Lesson Planet

#### Renting Cars, Stealing Money, and Linear Functions

When comparing pricing models, young mathematical consumers, create linear equations and analyzing them graphically and algebraically. They look at the meaning of slope and intercepts, as well as the intersection points of lines.

Lesson Planet

#### Creating Linear Models for Data 4

With this resource, high schoolers solve 17 types of problems related to the transformation of linear functions. First, they define parent function and determine how other linear functions compare to the parent function. Then, pupils...

Lesson Planet

#### Middle Grades Math: Balancing Equations

Learners solve linear equations. By observing the graph of each side of an equation using the TI-nspire graphing calculator, your class gains insight into solutions, as well as balancing equations and transforming linear equations....

Lesson Planet

#### Smarter Balanced Sample Items: 8th Grade Math – Target C

Target C from the Smarter Balanced assessment for eighth grade is understanding the connections between proportional relationships, lines, and linear equations. A slide show includes items about graphing proportional relationships and...

Lesson Planet

#### The Submarine

Submerge yourself in the study of slope. Scholars investigate a situation involving slope and the rate of change of a submarine. An additional example further explores the concept of slope by changing one of the conditions of the submarine.

Lesson Planet

#### Slippery Slope

Explore slope using geometric patterns. Young mathematicians investigate towers built from cubes to develop a linear pattern. They move the data to a coordinate plane to connect the pattern to slopes.

Lesson Planet

#### Equations of Lines

The intent of this resource is to show algebra learners that there is a proportional relationship between two lines that have an intersecting point. As the coordinate x increases by a constant, the y coordinate also increases. It will...

Lesson Planet

#### Countdown Challenge: Using Functions

Kids use functions to solve and graph 3 different problems that include following steps to graph various functions. First, they create a formula to calculate the cost of different numbers given in a table. Then, they determine the cost...

Lesson Planet

#### Linear Inequalities in One and Two Variables: Rays and Half Planes

Define rays and half planes, including the concepts of boundary lines and prerequisite knowledge of coordinate planes. Given linear inequalities in one and two variables, your class will compare the differences. They will also graph...

Lesson Planet

#### Linear Equations

Pre-algebra pupils examine the rate of change and how we can interpret it as a linear function. They are introduced to slope-intercept equations and graphs. Plenty of instruction is provided along with example problems. Note that even...
