Students discover that side measurement is used in determining angle classification of a triangle. By squaring sides, they predict whether triangles be right, obtuse, or acute. They prove the Pythagorean Theorem and use it to solve...

Students complete tasks. In this Seven Intelligences instructional activity, students complete a variety of activities that are all based on the seven different intelligences humans are supposed to possess based on Dr. Gardener's theory....

Students learn and review basic geometric terms, definitions, and theory, including regular polygons, lines, angles, points, etc. They make a tessellating stamp and create a repeating work of art.

Students examine and compare traits of humans and crocodiles.  In this crocodile lesson students use a ratio to estimate the height of a person and compare that to a crocodile. 

Students identify lines of symmetry.  In this symmetry activity, students create objects and identify their lines of symmetry.  They answer questions about lines of symmetry.  Students cut shapes out of cookie dough and...

For this frames of reference worksheet, students solve 5 problems given the details of a journey an ant takes from the center of a CD ROM to its edge. Students draw a scaled sketch of the turntable showing the motion of the ant from...

Students are asked to describe to a partner how he or she walks to school or the bus stop. They are shown on the overhead an one-inch grid paper, and at the intersection of two lines on the grid paper, students are shown a house and...

In this circles activity, 10th graders solve and complete 20 different problems related to various circles. First, they find the radius and diameter of a circle with a given circumference. Then, students determine the measure of each...

In this Pythagorean theorem instructional activity, 9th graders solve and complete 8 different types of problems. First, they go to the given website and copy the picture shown. Then, students draw a right triangle using the straight...

Seventh graders recognize the characteristics of isosceles triangles. For this isosceles triangle lesson, 7th graders use geoboards to create isosceles triangles. Students record results and explain why they have an isosceles triangle.

Pupils are introduced to the notion of a complex number and function iteration in order to motivate the discussion of Julia sets and the Mandelbrot set.

Students identify relation, function, patterns and range. For this algebra lesson, students factor and graph quadratic equations. They use transformation to move the parabola around and make predictions.

Students use triangles to find the length and slope of each side. After connecting the vertices, they add points based on their specific instructions. They use the Pythagorean Theorem to complete a worksheet to end the lesson.

Students use the Pythagorean Theorem to explore sailboat design. In this Pythagorean Theorem lesson, two sides of a triangular sail are measured, and the theorem is used to calculate the third side. A worksheet, bulletin board design,...

In this Algebra I/Algebra II learning exercise, students determine the equation of a line from the graph.  The one page learning exercise contains ten problems.  Answers are not provided. 

Students solve system of equation. In this algebra instructional activity, students graph, substitute and eliminate to solve system of equation. They identify the point of intersection and how many solution each system will have.

Students are introduced to polyhedrons through using straw models to explore geometric solids and constructing Christmas tree ornaments using Epsom salt crystals. Students will view interactive videos and investigate and retrieve...

Students explore the concept of fractals. In this fractals lesson, students play the "Chaos Game" via an applet. Students place dots on the screen to recognize that they have created Sierpinski's Triangle.

Students examine statistics by completing a skateboard measuring activity. In this flex instructional activity, students define what skateboard "flex" refers to and identify the proper method of measuring flex by conducting an experiment...

Learners explore the concept of Mandelbrot sets and Julia sets. For this Mandelbrot and Julia set lesson, students use a function integrator applet to investigate two-variable function iterations. Learners use Julia set and Mandelbrot...

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.

Students 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 solve...
