Lesson Planet: Curated OER

#### A Lesson on the Supply and Demand of Toy Fads

Let's all Hula Hoop! Scholars research the supply and demand side of toy fads in the United States. They analyze video clips and news articles to complete graphs on how the supply curve slope works in concert with the demand for products...

Lesson Planet: Curated OER

#### The Mystery Line

Take the mystery out of linear functions. Provided an image with no scale, learners guess where the line that connects them might cross the y-axis. After providing the coordinates of the points, they realize scale is an important...

Lesson Planet: Curated OER

#### Snow Day

Who doesn't like a snow day? Learners watch a snow accumulation over a span of 10 hours. They use that information to make a prediction of the total snow that fell during the 23-hour snowfall. Will it be enough to cancel school?

Lesson Planet: Curated OER

#### Styrofoam Cups

How many cups does it take to reach the top? Learners attempt to answer this through a series of questions. They collect dimension information and apply it to creating a function. The lesson encourages various solution methods and...

Lesson Planet: Curated OER

#### Energy Perspectives

The data says ... the resource is great to use. Using Microsoft Excel, pupils analyze data from the US Department of Energy in the fifth lesson of a 25-part Energy Systems and Solutions unit. Each group looks at a different data set and...

Lesson Planet: Curated OER

#### Linear Inequalities

An interactive lesson helps individuals learn to graph inequalities in two variables. Scholars can adjust the interactive to present the inequalities in standard or slope-intercept form.

Lesson Planet: Curated OER

#### Linear Function Machine

What goes in must come out! Learners play with a function machine to determine the correct function. They enter input values and watch as the machine produces the output.

Lesson Planet: Curated OER

#### Incline

Study velocity while examining graphical representations. As scholars work with the animation, they discover the effect the height of an incline has on the velocity of the biker. They make conclusions about the slope of the line in terms...

Lesson Planet: Curated OER

#### Linear and Non-Linear Function Distinction: Domain and Range of a Function

Functions are special types of relations, but what makes them so special? Pupils use an interactive to slide a vertical line across six different graphs. Ten challenge questions then assess understanding of functions.

Lesson Planet: Curated OER

#### Graphs of Linear Functions: Line Designs

Designs from lines are sublime. Scholars create colorful designs by connecting points on an interactive coordinate plane. They answer questions about slope and quadrants based on their designs.

Lesson Planet: Curated OER

#### A Matter of Density

Larvae transportation on the New England seamounts is based on the density of the water. Scholars calculate density and graph salinity versus temperature to better understand the distribution of organisms in a water column. Discussions...

Lesson Planet: Curated OER

#### Surrounded and Covered

What effect does changing the perimeter have on the area of a figure? The five problems in the resource explore this question at various grade levels. Elementary problems focus on the perimeter of rectangles and irregular figures with...

Lesson Planet: Curated OER

#### Functions 1

Scholars learn what it means for a relation to be a function and see various representations of functions. After learning the definition, they participate in a card sorting activity classifying relations as functions or not.

Lesson Planet: Curated OER

#### Toilet Graph

Mathematics can model just about anything—so why not simulate the height of water in a toilet bowl? The lesson asks pupils to create a graphical model to describe the relationship of the height of the water as it empties and fills again....

Lesson Planet: Curated OER

#### Vencent's Graphs

I like algebra, but graphing is where I draw the line! Worksheet includes three multiple-part questions on interpreting and drawing line graphs. It focuses on the abstract where neither axis has numbers written in, though both are...

Lesson Planet: Curated OER

#### Party

Thirty at the party won't cost any more than twenty-five. The assessment task provides a scenario for the cost of a party where the initial fee covers a given number of guests. The class determines the cost for specific numbers of guests...

Lesson Planet: Curated OER

#### Matching the Motion

It is not always easy to walk the straight and narrow. In the sixth portion of a nine-part unit, groups actively recreate a graph depicting motion. Individuals walk toward or away from a motion detector while trying to match a given...

Lesson Planet: Curated OER

#### Forms of Linear Equations

Linear equations are all about form. The fifth part in a unit of nine works with the different equivalent forms of linear equations. Class members become familiar with each form by identifying key aspects, graphing, and converting from...

Lesson Planet: Curated OER

#### The Challenge Question

A research position becomes a modeling job. The introductory instructional activity in a series of nine presents the challenge of analyzing a set of bivariate data. The class brainstorms what the data may represent. Pupils must decide...

Lesson Planet: Curated OER

#### Energy Skate Park

Skate through a simulation on energy with an a activity that uses a computer simulation of a skater to reinforce the concept of conservation of energy. The resource guides pupils through scenarios using the computer simulation to see the...

Lesson Planet: Curated OER

#### Matching Situations, Graphs and Linear Equations

What do guitars, candles, and helicopters have in common? They're all in this resource. Learners complete an assessment task to determine the amount of profit made in a guitar class based on given information regarding variable...

Lesson Planet: Curated OER

#### Comparing Lines and Linear Equations

Scholars first complete an assessment task on writing linear equations to model and solve a problem on a running race. They then take part in a card matching activity where they match equations and graphs of lines to diagrams of fluid...
