Learners investigate the area of various figures. They construct triangles and quadrilaterals using Cabri Jr. and discuss the relationships between different angles, side lengths, and figures.

Students explore the ways Geometry can help solve probability problems. Students describe platonic solids and practice calculating probability using an online resource. They construct dice with various numbers of sides to demonstrate...

Students investigate the physics of flight through various experiments. In this physics lesson, students construct different flying objects. They explain the dynamics that make these object fly.

Students harness the power of the sun to design, construct and evaluate a solar-powered model car of their creation. They race their cars in a "Solar Sprint" race modeled after the National Renewable Energy Laboratory's Junior Solar...

Students construct and maintain a school garden. In this gardening lesson, students plan the construction of the garden by writing letters to local businesses asking for supplies and materials; students build the garden using their math...

High schoolers construct perpendicular bisectors using Cabri Jr. on their graphing calculator. They then construct conditional statements about perpendicular bisectors along with their converse, inverse, and contrapositive.

Students construct models of hydrocarbon molecules using candy and toothpicks. For this hydrocarbons lesson plan, students are given a sheet with the molecular formulas of hydrocarbons. As a group, they construct each molecule using...

In this pre-calculus worksheet, students solve for angles formed by a tangent line and a circle. There are 6 different worksheets containing 8-10 problems per sheet.

Second graders design and sketch a model house. In this technology lesson, 2nd graders construct their house using teacher provided materials. They present their finished project and explain their design in class.

Learners explore and discover how the sun provides heat to the earth, depending on the surface as well as the angle of the sun's rays.

Students construct aluminum foil boats that float while holding the greatest number of pennies. They investigate the concept of water displacement, record their results, and watch a Bill Nye video on buoyancy.

Students investigate the reason for seasons on Earth during three activities. They construct a model of the Earth and Sun to identify patterns in the changes of the angle of light on the Earth's surface. Then they conduct a heat...

Students study China's cultural and economic complexities through a slide show that is written, read, and photographed by a Peace Corps Volunteer. They answer the questions: What does SARS stand for? [Severe acute respiratory syndrome]...

High schoolers investigate parallel and perpendicular lines. They use Cabri Jr. to construct and explore the relationships between the slopes of parallel and perpendicular lines. The drawing and measurement tools available with Cabri Jr....

High schoolers explore the concept of quadrilaterals as they find the midsegments of quadrilaterals using Cabri Jr. on a graphing calculator. They find midpoints, slopes, angles, and distances of lines and angles.

Students prove the theorem of Pythagoras. In this Pythagorean Theorem lesson, students define the different parts of a right triangle. They use the Pythagorean Theorem to solve for the missing sides and angles of a right triangle.

Students identify and construct figures that tessellate. They investigate which regular polygons tessellate and how to modify them to make other tessellating figures. Students explore how naturally occurring tessellations have been...

Scholars explore parallelograms in this geometry lesson. They investigate the properties of a parallelogram. Assisted by technology, your learners will construct a parallelogram and examine the sides, angles, and diagonals to discover...
