Cheaper cell phone bills? Learners compare two different cell phone plans for a specified number of minutes of phone usage each day. They also determine the conditions for which one plan is cheaper than the other.

Design an efficient cereal box. Scholars use set volume criteria to design a cereal box by applying their knowledge of surface area to determine the cost to create the box. They then determine whether their designs will fit on...

Students use authentic satellite data on the NASA website to determine when the sea surface temperature meets the criteria to induce coral bleaching.

Students design an experiment to test the variables involved in the hatching of the Bruchid beetle.

Learners explore the Pythagorean Theorem. For this math lesson, pupils solve problems using the Pythagorean Theorem. They select the appropriate numbers to substitute in the formula to solve problems.

Scaling needs to be picture perfect. Pupils use proportional reasoning to find the missing dimension of a photo. Class members determine the sizes of paper needed for two configurations of pictures in the short assessment task.

Students, after entering the given conditions into FoilSim, apply calculus techniques to verify predictions.

While creating models from data, pupils make decisions about precision. Exercises are provided that require linear, quadratic, or exponential models based upon the desired precision. 

Fourth graders engage in a study of sound pollution at their school. After a class discussion on what noise pollution is, learners are asked if they think there are areas of their school or community where noise pollution is a problem....

Students investigate money. In this consumer math lesson plan, students use coins, identify their value, then group them in various ways to equal a dollar.

Students estimate the total cost of a shopping trip. In this estimation lesson, students use three different techniques to estimate how much a shopping trip will cost.

Students calculate probability. In this lesson on probability, students use given data to calculate to chances of a given event occurring. Many of the calculations in this lesson are applicable to daily life.

Students calculate derivatives from a set of data. For this calculus lesson, students estimate the limit at infinity. They complete a Return Interval handout at the end of the lesson.

Students work in small groups to solve the problems presented. The main project, mapping the classroom, use these discussions to collaborate in creating a tangible demonstration of their understanding.

Minimize the time it takes to create a fish dish. Scholars use their knowledge of time to devise an order that accounts for different constraints. Considering jobs that can be done in parallel is essential to solving the problem.

Life's not fair, but decisions can be. The 17th installment of a 21-part module teaches learners about fair decisions. They use simulations to develop strategies to make fair decisions.

Students demonstrate an understanding of aircraft launch airspeed requirements. They read a selection on relative velocities from a NASA Web-based textbook, then calculate airspeed launch requirement problems.

Students explore the cost of wasted water. In this math activity, students conduct an experiment in which they collect data on how much water is lost when a faucet leaks. Students figure the cost of the water that was wasted.

Third graders create a model of the solar system. In this solar system lesson, 3rd graders create a scale model of the solar system. Working in pairs students solve mathematical problems to correctly measure the distance each planet is...

Students investigate the problem of osmosis by conducting an experiment. They use eggs with the shells dissolved to tell whether fluid can move across the membranes. The experiment provides high interest for all kinds of students to keep...

Students determine what makes Charleston, West Virginia unique. In this West Virginia history lesson, students explore the West Virginia History Museum to identify why Charleston became the capitol of the state.

Students examine percents. In this percents activity, students will estimate percentages. Using advertisements from a newspaper, students problem solve to determine the final price of a sale item.

Learners conduct their personal investigations into paper airplane flight. Cooperative teams are formed, with students choosing the paper airplane design that they are most interested in building.

Seventh graders examine different countries in Africa to research. They choose one to concentrate their research on using the five themes of geography. They design a multimedia presentation that will make up the African safari.
