High schoolers differentiate between similarity and congruence using polygons. In this geometry lesson, students label triangles based on their properties. They find missing sides and angles using the interior sum theorem.

Students represent and solve problems using geometric models and apply geometric properties and relationships. They also practice constructing and measuring angles. By constructing, drawing, visualizing, and comparing geometric figures...

Focus on the Latin roots struct and tract with this PowerPoint, boasting plenty of practice opportunities. To help develop a definition of each root, viewers match a list of words to their pictures. Then, they compare those words to a...

Learners calculate volume using the correct formula and the correct unit. They explore different prisms, spheres, cubes, and cones as they calculate volume and relate it to depths in oceans.

If you set up a triad of mirrors into a corner figuration, they act as a kaleidoscope, bouncing light waves back and forth indefinitely, changing the light that your eyes perceive. Although the materials required are very specific and...

High schoolers determine the surface area of the Luxor Hotel, using the square feet of the base, volume, and the volume formula. They create a scale model of the triangular/pyramid shaped hotel.

Examine ratios and proportions in several real-world scenarios. Children will calculate unit rates, work with proportions and percentages as they plan a party, purchase produce, and take a tally. This lesson plan recommends five...

Students explore the concept of triangle inequalities.  In this triangle inequality lesson, students cut spaghetti noodles into given lengths.  Students use the noodles to complete a worksheet about triangle inequalities. ...

Pupils engage in a instructional activity which reinforces the concepts of clockwise and anti-clockwise rotation, while developing an understanding that angles are measured in degrees. They utilize a mathematics educational program to...

Learners investigate the angle of light and how it faces the earth. They conduct a series of investigations with the following two objectives. Students determine if the angle of light is a factor in the absorption of heat. They correlate...

Pupils find the altitude of the Sun at 10 A.M., at solar noon, and at 2 P.M. by measuring the height of the gnomon and the length of the shadow at each time. They record the measurements in their notebooks for later conversion.

Students discuss and work with lines of symmetry. In this symmetry lesson, students start with a warm up activity on metric conversion. They talk about the definition of symmetry and reflection before completing a worksheet.

Students determine if the angle of light bombardment is a factor in heat absorption. They correlate these findings to the tilt of the Earth and the seasons. Students fold a pice of black construction paper in half, lengthwise. They tape...

Students examine parallax and angular measurements.  In this investigative lesson plan students calculate distances of objects and map their results.

In this Aurora Borealis worksheet, students read about how early scientists used triangulation to measure the height of the Aurora Borealis. Students solve 3 problems using triangulation.

Fifth graders engage in a variety of hands-on and technology-rich activities involving the classification of quadrilaterals. They utilize protractors and rulers to investigate the characteristics of various types of quadrilaterals. They...

In this triangulation worksheet, students solve and complete 11 steps of an experiment to determine the distance to a far away object using triangulation and trigonometry. First, they select a far away object and create a baseline far...

Learners identify the six trigonometric ratios and properties. In this trig lesson, students define basic trig functions as it relates to solving right triangles. They identify the equation for sine as o/h and cosine as a/h and tangent...

Students study West Virginia quilts. For this mathematics lesson, students use symmetry, geometric shapes, and patterns to create their own quilt square.

Students collect data to create different types of graphs-line, pie, and bar graphs. They use StarOffice 6.0 to create graphs.

Students determine that two figures are similar or congruent by investigating figures that are similar and figures that are congruent. They prove that two figures are similar or congruent by using definitions, postulates, and theorems.

Students watch teacher demonstration of distance formula, view non-collinear cities on maps, plot points on coordinate plane, evaluate square roots, compute distance between two points, and use Heron's formula to find area of triangles.

Students conduct an experiment to determine if a plant's response to gravity is affected by different angles of plant orientation.

Here is a math lab that helps young mathematicians understand the real-life meaning for vector addition. By building a model using spring scales and washers as weight, and then calculating the vector addition using two different methods,...
