Astronomers practice downloading data from a high-energy satellite and translate the data into colored or shaded pixels. As a hands-on activity, they use pennies to simulate high-energy satellite data and they convert their penny...

We landed on the moon with less computing capabilities than you can find in this app! Here is a multiple function calculator that takes all the power you get from a handheld and adds the wonderful large screen that only a tablet can...

Create a shift in TV viewing habits. The interactive presents a cosine model of an individual's TV viewing habits during a year. Class members move the model to reflect given conditions. Finally, they determine key features from the...

Scatter the TV sales over weeks. Pupils create a scatter plot to display the number of TV sales over a period of several weeks. The interactive allows class members to create two lines of best fit. Then they determine which line fits...

Teach how graphic designers can use mathematics to represent three-dimensional movement on a two-dimensional television surface. Pupils use matrices, vectors, and transformations to model rotational movement. Their exploration involves...

Sixth graders visualize different percentages as parts of a whole on visual images. They observe alterations of photographs, and models of circles, squares and sets. This incredibly detailed, eight-page plan leads you through everything...

Third graders identify two and three dimensional shapes used in architectural designs by viewing images on the Internet.  In this geometry lesson, 3rd graders create their own building designs and identify the geometric shapes that...

Young learners view different shapes drawn by the teacher on the board. The teacher identifies each shape by name and discusses the importance of knowing the difference between shapes when building something. The pupils complete the...

Challenge your class with this fun and engaging engineering design project. The goal, to create a brand new cereal complete with a list of ingredients, a name and logo, and a box to hold it in. Starting with a survey to determine the...

While the process of buying a home can certainly be overwhelming, give your young adults a leg up for their future by introducing them to the components of a mortgage, as well as exploring the basic concept of credit and how to become...

When it comes to rating educational calculators, this calculator is always near the top of this list. Now it's available as an app. There is a lot of calculator power wrapped up in this app. Not only is this a fully functioning...

Students are taught that they can gather information about objects using the five senses of vision, touch, smell, taste, and hearing. They are told that some sensing, like sight, is done remotely. Students observe how a camera can...

In this STEREO satellites activity, students are given a chart with the intensity of the signals from the satellites received on Earth and the distances of the satellite from Earth. Students convert the intensity at each distance to...

Students perform transformations and translation on a coordinate plane. In this geometry instructional activity, students move shapes around on a graph identifying translation, image, and transformation. This instructional activity has...

What a bargain—an informative, free resource! Given prices of several objects, learners determine whether 20 percent off or $20 off would be a better bargain. They use the results to come up with a generalization of the situation.

Learners calculate the pixel density of a specific cell phone using the concept of similarity. They use information from the cell phone's website to make their calculations and then compare their results to the posted information.

Fifth graders accurately measure the distance to eight points on an uneven surface by conducting a simulation of sattelite altimetry. They create a two-dimensional model of the simulated ocean surface by graphing data from the Radar Run...

Students use their understanding of 3D on 2D to make a representation of a 4D form on paper.

Scholars use interactive resources to figure out how to mathematically draw a reflection of a geometric shape viewed in a mirror. To conclude the activity, class members are asked to deduce the result of multiple reflections across...

In this same or different worksheet, students look at four objects and determine which one does not belong. They click on the object that is different than the others.

Learners predict the shape of a geometric figure in 3D. In this geometry lesson, students construct 3D shapes to perfect their knowledge of measuring and predicting. This assignment is also available as an online interactive...

Students examine how businesses and corporations contribute or sponsor activities for the common good. They read annual reports of major corporations to determine how they contribute to focused activities for the common good.

Students write a proposal with an appropriate budget to establish a health day at school. They design this day to educate and promote good health. They educate other students about health care, inform students of health concerns, and...

Students observe and discuss a picture of Curious George building a bridge and discuss what it means to build, plan and design a project. As a class, they list things they need to do in oder to build something and explore how a compass...
