By mounting a light bulb on a stand and a PV cell on another, physics apprentices experiment with the angle of incidence. Their goal is to determine the optimum angle for collecting solar energy. The use of a scientific calculator...

Use the given tasks and detailed teacher's commentary to introduce your 8th graders to the Pythagorean theorem and its converse. Embedded links to information about Egyptian geometry make your presentation interesting. Consider...

Teach your class how to apply their knowledge of geometry as they explore the unknown. In order to find an unknown angle, students must understand that rectangles have four interior right angles, that right angles have 90 degrees, and...

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...

Individuals read tables with temperatures and times in order to distinguish the town with the lowest temperature or most extreme temperature difference. Each of the eight questions has three sub-questions that use the same charts. 

Make an estimate by getting in line. The class works with scatter plots and lines of best fit to make an estimate for given values. Pupils determine whether there is a positive or negative correlation and draw a best-fit line. Using the...

Viewers are presented with seven problems with parallel lines and angle relationships and must use the given information to find the measures of specific angles. To finish, they explain their process in finding the measures in the...

Explore the behavior of light waves with a lab activity. Scholars build new vocabulary through experimentation and observation. Using different mediums, they model reflection, refraction, transmission, diffusion, and scattering of light.

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.

Students investigate geometric relationship using conjecture about linear pairs and vertical angles. In this geometry lesson, students apply their theorems and previous geometry knowledge to solve for and find angles of linear...

Why are only four colors needed to color webs from regular pentagons, not five? An assessment task requires young mathematicians to first construct regular pentagons using a compass and straightedge, then has them consider a shape...

Allow your pupils to become the mathematicians! Individuals explore the properties of a midsegment of a triangle through construction and measurement. Once they figure out the properties, learners use them to draw conclusions.

In this geometry instructional activity, learners create circle, line and bar graphs using different comparisons of events. There are 24 questions with an answer key.

By using circles that they cut out and label themselves, learners literally "get a grip" on the angles they identify: supplementary, complementary, and vertical. They solve missing measurements based on properties of supplementary,...

How many different types of triangles can your class name? A discovery lesson guides learners through an exploration of the different triangle types and the relationships between their angles and sides. Using coordinate geometry,...

Sixth graders investigate different types of angles. In this geometry activity, 6th graders use a protractor to identify acute, obtuse, and straight angles.

High schoolers view examples of a ray, opposite rays, collinear rays, angles, and straight angles. They discuss and demonstrate how to use a protractor and complete worksheet problems on rays and angles.

Students make jewelry using different shapes from magazines, tissue paper, cardboard, and other materials. In this making jewelry lesson plan, students complete this hands on activity to discuss how shapes are used.

Learn how to display data. Young data analysts watch a video to review how to create cumulative frequency histograms and box plots. They work on a set of questions to practice producing these data displays.  

Learners investigate the connection that exists between Algebra and Geometry. They classify two and three-dimensional figures. Pupils use formulas to solve problems in geometry and use appropriate measuring devices in the right contexts.

Learn ways to simplify algebraic fractions with a video that reviews how to simplify rational expressions by canceling common factors and how to add and subtract simple rational expressions. A worksheet tests pupils' understanding...

Explore how to convert repeating decimals to fractions with an informative video that teaches young mathematicians how to translate between decimals and fractions. After viewing, individuals complete a set of problems to practice...

Direct your young mathematicians to a resource on direct and inverse variation. A video first reviews concepts on direct and inverse proportionality. Individuals then answer a set of questions in pure and applied mathematics...

In this measuring angles worksheet, students solve 10 problems in which angles are measured with a protractor and labeled with: acute, obtuse, right.
