Students analyze the relationship between speed, time and distance. In this math lesson, students plan a school trip. Students determine the efficiency and cost effectiveness of a trip.

Students describe, make and compare polygons. In this creating polygons instructional activity, students identify properties of quadrilaterals and describe common features of two dimensional shapes.

Students, working on their GED, examine the steps used to resolve the unknown sides of a right triangle. They express the square root function as an exponential function and derive the distance formula using principles of geometry.

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 find number patterns in the generation of several different types of fractals.

Students explore the concept of fractal patterns. For this fractal pattern lesson, students use an applet about the Hilbert Curve to answer questions about rectangles and other polygons. Students derive the fractal pattern when dividing...

Students are introduced to lines, rays, line segments and planes and study the differences between them. They also practice graphing lines, rays, line segments and planes

Young scholars stud angles, and then play the "What's Your Angle?" game. They complete at least 10 computer generated problems from the Angles Applet.

High schoolers examine the concept of scatter plots. They compare baseball statistics to locate the ones that correlate with winning, and identify the positive, negative, and no correlation in sets of data using MS Excel.

High schoolers explore the concept of irregular fractals. For this irregular fractals lesson, students discuss how to find fractal dimensions through teacher led discussion. High schoolers calculate fractal dimensions of various fractals.

Pupils determine that knowledge of an event's outcome can affect the probability of the unknown outcome of an event that has already occurred.

Students investigate the concepts that are related to finance and how it is used in the world. They take part in activities that are focused around the use of a spreadsheet while using a T-chart to simulate a ledger of credits and debits.

Fifth graders are introduced to convergence of sequences based on averaging previous terms in the sequence. The power of the "fill-down" function in spreadsheets is exploited. By using various starting numbers, and inferring the limit,...

Young scholars explore problem solving strategies. Given real life problems, students examine the sum of consecutive strings of whole numbers. Young scholars use diagrams and sequencing to solve problems. Students justify their...

Young scholars develop the skills of problem solving and logical analysis. The conditions of when two subtraction sums are equal is examined to develop other skills like practicing arithmetic in context.

Students make an inquiry with the aid of technology into the concept of functions. The emphasis of the lesson is on the interplay between the geometric and analytic information.

Examples and a video lesson help to explain proofs and logic. [1:57]

Here is a site that clearly and thoroughly explains the Pythagorean Theorem from solving for missing sides of a right triangle through its proof. There are example problems solved, problems for the student to attempt, and answers to the...

Determine whether the stated polynomial identities are in fact true and whether the proofs given of such identities are valid. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video, or...
