Investigate the process of combining like terms using an interactive animation. Scholars tackle simplifying expressions by manipulating rectangles that represent the terms. They add and subtract terms to arrive at the result.

Get a little batty with life science! This fun simulation game replicates how bats use echolocation to hunt moths in their native Hawaiian habitat. After creating blind folds and discussing some basic principles of echolocation, students...

Watch the exponent expression do the negative exponent dance! An interactive lesson uses an animation to show how negative exponents become positive. Learners manipulate the expression and then respond to conceptual questions.

Let your eager learners practice their basic arithmetic and spelling skills with this fun interactive resource! For any primary grade teacher with access to an Apple mobile device, this is a must-have application.

Be a hero, not a zero! Help your classes understand how to solve quadratic equations with the zero product property using an animated simulation. Using the controls, scholars manipulate the zeros and watch as the function and its factors...

Get on track to learn about slope-intercept form. Scholars use an interactive to position a line along the tracks of cable car. Applying knowledge of slope and intercepts, they write the slope-intercept form of the equation for the line.

The ways that animals adapt to their environments is quite remarkable. For this life science lesson, fifth graders take a look at some of the ways that aquatic animals that live in Arctic or Antarctic waters survive. They perform an...

Young learners listen to the book Rooster's Off to See the World, and complete simple math activities using the book. In this simple math lesson, students read and list the animals in the book. They arrange animal picture squares using...

Watch as a function machine converts an input to an output. Learners determine the work applied by the function machine to write a function rule. Questions accompany the function machine animation to guide individuals to conclusions.

How is a mean affected by changes in data? A well-designed animation allows individuals to manipulate data and watch the effect on the mean. Challenge questions help guide users to conclusions about outliers and skew within data.

Model the distributive property with jars of fireflies! An interactive animation has learners manipulate the number of jars of fireflies to determine the number caught. Accompanying questions ask scholars to consider the multiplication...

Find the perfect amount of water for lemonade. Scholars solve the famous problem of measuring four liters of water using a three-liter container and a five-liter container. An interactive allows users to see each step of the solution.

Students learn the basic definitions of a quadrilateral, parallelogram, rectangle and square and explain the relationship/classification process between them.

Explore the advantages to using a stem-and-leaf plot using an online lesson. Learners manipulate an animation to create a stem-and-leaf plot. They then calculate statistics for the data using their display. Guiding questions help them...

Students listen to Courtney Baker's, "The Perfect Pet," on a day they bring a stuffed animal to school. They graph the types of stuffed animals that their classmates brought to school before answering questions based on the graph. Next,...

Fourth graders provide a habitat for live mealworms and observe their life cycle. In this animal life cycle and scientific inquiry lesson, 4th graders create a habitat for a live mealworm and observe and record related data as it grows....

What are the advantages to seeing multiple data sets on the same graph? Scholars explore this question as they manipulate the animation within the lesson. Questions within the interactive ask individuals to make comparisons across the...

Model function operations using a function machine. An interactive lesson has learners determine the patterns of a double function machine. They use the patterns to write functions and make connections between the inputs and outputs.

Teach the concept of simple random sampling through an interactive lesson. Learners explore the concept by considering the strength of sampling methods. Size of the samples varies also as individuals determine which methods lead to the...

Introduce the concept of a correlation coefficient using an interactive lesson. Learners begin by manipulating a correlation coefficient and watching a graph change to represent the new value. Questions help strengthen their...

Cameras use histograms to communicate the exposure of a photograph. An interesting lesson uses this idea to help learners deepen their understanding of histograms. It highlights the skew of the graphs by showing under- and overexposed...

Explore the strengths and weaknesses of box-and-whisker data display. An interactive lesson asks learners to create a box-and-whisker plot from a set of data. Challenge questions focus on determining what types of conclusions they can...

Students poll classmates to gather information for a graph. They identify three types of graphs (bar, line, table). Students create each type of graph using data gathered from classmates.

Students solve equations of the form ax+b=cx+d and visualize the concept of "balancing" an equation.
