Students explore the concept of area under a curve. In this area under a curve lesson, students find the area under a curve using the Monte Carlo method using random points and probability. Students calculate the area under the same...

In the process of constructing their own "rulers" Students develop a sense of the size of a centimeter and meter. Students select the appropriate "ruler" for the tasks. Finally, 3rd graders calculate the perimeter of objects using...

Students order five weighted plastic eggs in order from lightest to heaviest.

Learners explore the concept of similarity. They examine such topics as ratio of corresponding sides, internal ratios and scaling factors. After watching a video, student groups perform experiments outside the school building.

Students demonstrate how to use math skills to measure their lung capacity. In this human biology lesson plan, students use a clear plastic container, measuring cup and rubber balloons to demonstrate how the lungs work. Students estimate...

Students listen to an explanation of yeast cells and how they effect bread and beer. They discuss the ways alcohol affects the human body and participate in an indirect observation about cell respiration in yeast-molasses cultures.

In this similar figures instructional activity, students use proportions to solve 6 short answer and multiple choice questions.  Students use proportions to answer questions about map scales and height of trees given shadow lengths.

In this Drake Equation worksheet, students read about how scientists can estimate the number of intelligent civilizations that may exist in our galaxy. Students answer 7 questions about the Drake Equation and they use the internet to...

Learners investigate the side splitter theorem. In this geometry lesson, students estimate and solve problems dealing with ratios and proportions. They identify angles created by lines that are parallel.

In this geometry worksheet, 10th graders review the vocabulary associated with the special segments of a triangle and the associated points of concurrency and solve problems in which they find the indicated missing angle or...

Students find percents and unit price using popcorn.

Twelfth graders apply estimation techniques to determine how high any one basketball player can jump.

Students discover the reproductive parts of a plant.  In this biology lesson, students identify and categorize several different plants they dissect in class.  Students record their information using a data chart.

Ninth graders find the height of every day objects using techniques learned through postulates that allow triangles in a problem to be similar. They calculate the length of a missing side and solve proportions.

Fourth graders determine the value of ? by measuring the circumference and diameter of circular objects such as soup cans, Oreo cookies, etc..

Students find the identity o sine, cosine and tangent. In this precalculus activity, students solve and identify the different parts of a right triangle. They use the ratios of the Pythagorean Theorem to find the missing side or angle.

High schoolers pretend they are hiking up a mountain. They practice making calculations on angles and elevation. They use topographic maps to estimate distances and trigonometric ratio methods.

Students participate in an estimation activity to determine the length of a hallway or to estimate how many people can fit in the school stadium or gym.

Students explore the concept of the Pythagorean Theorem. In this Pythagorean Theorem lesson, students derive the distance formula and slope of a line from the Pythagorean Theorem.

Second graders, in groups, prepare a list of proposed record ideas for the class book.

Third graders create a box big enough to hold a million dollars. This is a project fun to do near the winter holidays with inexpensive gifts included in the boxes. This hands-on lesson very effectively demonstrates the concept of volume.

Fourth graders, in groups, design a paperclip grasshopper. They determine its ability to survive a prey by jumping high, far, or with a distracting behavior.

Students recognize the correlation between the trash they dispose of around their school and the environmental hazards that face wildlife, specifically the Laysan albatross. They determine three ways that they can help the albatross chicks.

Learners determine the area of two objects by superimposing one on the other. They compare and order the area of different shapes by covering a larger shape with similar smaller ones. They complete these activities as different stations.
