Tenth graders construct geometric figures using compasses and protractors.

Sixth grade students: design a stained glass window, submitting their initial plan detailing the measurements of all lines and angles. Seventh grade students: create a scale drawing of their own geometric family of four members.

In this transformations/translation worksheet, students draw transformations based on shapes and vectors of given translations. A reference web site is given for additional activities.

Young scholars access the Internet to find information on current hurricanes. They get locations, speeds, and air pressures and then plot the location of the hurricane on a hurricane-tracking map. They also access the FEMA website to...

Students investigate geometric shapes by creating figures on a plane. In this polygon lesson, students complete a worksheet based on the angles in a power polygon. Students identify the different types of polygons and define their...

Students observe a pendulum and graph their observation. In this algebra lesson, students use the TI calcualtor to graph the motion the pendulum makes. They analyze the graph and make predictions.

Learners collect data on population growth. In this statistics lesson, students graph their data and make predictions. They find the linear regression and the best fit line.

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.

Students look at ratio, what it means for numbers or objects to be in a given ratio, and how ratios and fractions are related. They write and solve story problems which involve whole numbers, using addition, subtraction, multiplication,...

It's time to discover what your classes have learned! The final lesson in the 25-part module is an assessment that covers the Pythagorean Theorem. Application of the theorem includes distance between points, the volume of...

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

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

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 explore the concept of irregular fractals. In this irregular fractals lesson, students discuss how to find fractal dimensions through teacher led discussion. Young scholars calculate fractal dimensions of various fractals.

Third graders use a number of problem solving strategies in this unit of lessons. They determine how to draw and model three-dimensional objects, use co-ordinate systems, determine probability of events, and identify paths of simple...

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.

Seventh graders examine the process of constructing a site plan map at archaeological sites. They discuss the process of mapping techniques and calculation of percentages, create a plan site map of a cellar at Jamestown, and calculate...

Learners study the nature of a satellite's orbit around the Earth.

Students explore movement and position concepts. They follow directions using left , right, up, down, North, South, East and West. Students draw and follow a path on a grid to show a route followed. They label and follow legends on a map.

Students will define circle and radius. In this radius lesson,  students are given a circumference, they will write an equation and sketch the circle. Students will match graphs of circles to their equations.
