What are the issues surrounding water quality? Viewers of this short presentation gain information about the importance of clean water, the lack of fresh water, water contamination, and ways that engineers treat water. 

Students, while in the computer lab working on a spreadsheet program, calculate interest and accumulated value of a savings plan. They follow specific directives on how to create their spreadsheets. At the end of the lesson they print...

In this math instructional activity, learners discuss the natural frequency ω0 of the system and how it is the number of oscillations of the spring in 2π units of time.

Young scholars use the Five E method to solve problems. In this Five E lesson, students complete math lessons using the Engage, Explore, Explain, Elaborate, and Evaluate technique. They use the Five E's with lessons on tessellations,...

Students engage in the opportunity to convert and rename fractions along with decimals and percents. They recognize the relationship between fractions, decimals, and percents. They apply fractions, decimals, and percents to real-world...

Eighth graders complete seven work stations that highlight math activities while they focus on the rules for Internet use and classroom rules for working in cooperative groups. After completing the activities, they complete a self-...

Second graders practice with fractions and fact families. For this fractions and fact families lesson, 2nd graders participate in a series of activities to assist them with understanding fractions.  Activities include graphing,...

Third graders divide by 2 and 5. In this math lesson, 3rd graders label the parts of a division sentence. Students solve division sentences using multiplication.

Students discover for which kind of linear function is appropriate to use the "scatter" or the "connected" term. In this lesson, students investigate functions using variables, patterns book, graph paper, rulers and the graphit program.

Six pages prepare you to introduce your math stars to the addition and subtraction of positive and negative numbers. They drive a robot back and forth on an actual number line to represent the operations. If you don't have access to a...
