Not all interactives are made equal. Scholars use an interactive balance to explore the concept of equality. They place different objects on balances to determine the number of each object needed to balance the scale.

Solving equations in two variables can't be that much harder than solving equations in one variable. Using a balance interactive, scholars solve equations in two variables. They apply inverse operations by adding -x, -y, or -1 as...

Find the right balance between concrete and abstract thinking. After using interactive balances to explore inverse operations, learners solve multi-step equations with variables on both sides. Of course, they can still use the...

Make sure the measurement is right. The interactive provides right triangles with a missing side measurement. Pupils use the given sides and the Pythagorean Theorem to calculate the length of the missing side. After entering the length,...

Far out — plan a trip to space! Aspiring mathematicians steer a space vehicle through an asteroid field, calculate currency exchanges to buy provisions, and determine placement of charges to blow up asteroids. Along the way, they learn...

Students use the Internet to read about an explorer's survival in the Antarctic. They try to find a better route for him to have taken.

Students complete fraction word problems using TI-Explorer Calculators.

In this comet tails and stars worksheet, students read about the star Mira and the vast clouds of gases it emits. They use a photograph from the Galaxy Evolution Explorer satellite to solve 5 problems about the scale of the image, the...

Ocean explorers or mathematicians research the wreck of the CSS H.L. Hunley. They investigate the actual dimensions of the Hunley using math and measuring skills. Afterward, they sketch a large scale drawing of the submarine outdoors on...

Young analysts examine changes in the nutria population, vegetation density, and marsh area over time in the wetlands of Louisiana. They import data and use the TI-73 Explorer to graph and analyze the effects of nutria on marsh loss.

Middle schoolers trace sailing route of Spanish and Portuguese exploration ships. They calculate and compare distances that different explorers traveled. Students calculate how long it would take to travel an explorer's route using...

Students use the Data Explorer software to organize and display the test scores for the classes in stacked box-and-whisker plots, then analyze the results in paragraph form.

Students investigate the TI-73 Explorer calculator.  In this middle school/high school mathematics lesson, students are provided with the step-by-step instructions to transfer DataMate software from the CBL 2 to the TI-73...

In this number 6 instructional activity, students trace the number 6 and color 6 different Dora the Explorer characters. Students trace the number 6, 5 times on this instructional activity.

Explore the relationship between perimeter and area. Learners input the area and perimeter for shapes on the Shape Explorer website, solve problems using geoboards, complete a worksheet, create a PowerPoint presentation, and take an...

Need to build a laser fence on Mars?  In this cute maximizing-area lesson, young explorers pretend to be prospectors on Mars and must determine the best way to use 20 meters of fencing in order to maximize their area. In addition,...

So many shapes in our vast oceans. Young explorers can discover new shapes in a variety of ways in this lesson. One way is having free exploration with a pattern shape kit handed out by the teacher. Another is by viewing a...

Who needs the daylight to simulate a lunar eclipse? Astronomers model the positions of the Sun, Earth, and Moon to explain the necessary conditions for a lunar eclipse. Investigators cut and label a paper plate to represent the Earth and...

Ten questions are provided to review elapsed time. Your third graders will like that some questions provide visual representations to guide learners. Use Internet Explorer if you want this worksheet to print in its proper format. 

Middle schoolers experience the dynamic skills and processes needed to design the next generation of launch vehicles at NASA. They view how mathematics, science and technology all work together to achieve excellence in human space flights.

Young explorers review the basic shapes (circle, triangle, square, rectangle) and practice putting them together to make new shapes. Given an outline of a pond, they recreate it by combining other shapes.

Students explore the concepts of length, perimeter, and area. In this math lesson, students use Shape Explorer to practice finding length, perimeter, and area.

Young scholars investigate the TI-73 calculator.  In this middle school mathematics lesson, students examine the procedures for downloading and installing applications to the computer for the TI-73 Explorer.
