Students identify the measure of missing exterior angles. In this geometry lesson,students define and apply the exterior angle theorem to solve problems. They use Cabri software to create different angles and make investigations.

Young scholars explore perimeter, volume, and area. In this math instructional activity, students explore how changes in dimensions of geometric shapes affect the perimeter, area and volume of the various shapes. Young scholars...

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

Students design and build their own solar cooker. In this math lesson, students determine the relationship between the angles of the sun, reflection and cooking time of the solar cooker. They test their project, collect data and...

Students apply properties of Pythagorean to solve problems. In this geometry lesson, students identify the different parts of a right triangle using ratios. they solve problems using squares and square roots.

Students are introduced to the problem and brainstorm ideas for approaching the problem and keeping track of what has been done. They work in pairs and share their answers, explaining their reasoning.

Fourth graders use colored beads in two problems and explore the use of proportional reasoning as a problem solving method. Working Students, in groups, explain their reasoning strategies orally, and through drawings.

Students use equations to represent practical situations. They solve linear equations and quadratic equations. The use of problem solving strategies is also developed.

Young scholars are introduced to the problem. They brainstorm ideas for approaching the problem and keeping track of what has been done. Students work on the problem in pairs to discover what strategies might help to find the answer.

Students explore the Mandelbrot Set. They are introduced to the concept of a complex number and function in order to motivate the discussion of Julia and Mandelbrot sets. Students investigate fractals and how they are built.

student make predictions or draw conclusions based on physical and visual representations of profit and sales. They model problems with physical materials and visual representations, and use models, graphs and tables to draw conclusions...

Pupils construct models of various tricubes, tetracubes, and pentacubes that are possible, classify n-cubes into different groupings, and draw these figures on isometric dot paper giving true perspective to what they visualize.

Seventh graders discover that there are multiple strategies to be used in problem solving. They explain a problem solving situation in their own words and determine a possible strategy for solving the problem.

Students build a working definition of regular fractal, look carefully at the concepts of dimension and scale, and are introduced to logarithms. They solve simple exponential equations for the exponent both by trial and error and using...

Students build a working definition of a regular fractal, they measure the concepts of dimensions and scale, they explore the concept of a logarithm and they attempt to solve simple exponential equations for the exponent both by trial...

Students are introduced to plotting functions on the Cartesian coordinate plane seen several categories of functions, including lines and parabolas

Eighth graders evaluate statistical equations. They examine data from archaeologists at Jamestown, complete statistical equations using the sets of data, and graph the results.

Students participate in a challenge to construct a rotation sensor with the highest degree of accuracy and repeatability. They conduct computer analysis of their sensor using repeated trial.

Eleventh graders sort different types of functions including rational, periodic, exponential, polynomial, quadratic, logarithmic and linear using "function cards." The functions are displayed in multiple representations including...

Learners explore the concept of transformations. In this transformations lesson, students construct an equilateral triangle and a square with a circumscribed circle. Learners reflect and rotate their constructions.

Students distinguish between possible and impossible graphs of functions, and to learn why some graphs are impossible. They have practiced plotting functions on the Cartesian coordinate plane

Students are introduced to the function and design of the following Lego pieces: beams, bricks, plates, axles, tires, hubs and bushings. They then work with a partner to build something using only these pieces.

Learners study the meaning, symbolism, and value of U.S. coins, especially the quarter. They conduct a survey of coins in students' possession, graphing the results to show frequency distribution and drawing inferences about the U.S....

Students read an explanation from the NASA Web-based "textbook", The Beginner's Guide to Aerodynamics, then use the information in combination with data from other Web sites to solve single variable equations for distance (range), time,...
