Students explore circumference and diameter. In this math lesson, students apply their knowledge of circumference and diameter to solve mathematical riddles. Students apply this knowledge to find circumference and diameter of various...

Students calculate the distance from the vertex of a triangle to the center. In this geometry lesson, students find the shortest distance between a point and the vertex of a triangle. They relate this concept of distance to the real world.

Pupils perform operation with secant and tangent lines. In this calculus lesson, students find the derivative and relate it to the slope of a line. They differentiate between secant and tangent as they intersect a circle, using Cabri.

Students identify missing sides and angles. In this geometry instructional activity, students use triangular theorems to identify the missing sides. They use the Pythagorean Theorem to find the different ratios of each side.

Students find the median of trapezoids and other polygons. In this geometry lesson, students identify important properties of trapezoids. They create trapezoids and polygons using Cabri software.

Young scholars build and apply concepts of geometry. In this geometry lesson, students create a building using proportions and scale drawings. They use Cabri technology to create a virtual drawing first.

Students construct using Cabri software. In this geometry lesson, students convert between units and apply the correct measurements to build objects. They create the room virtually and manipulate the shapes to the desired measurements.

Students identify and define properties of triangles. In this geometry lesson, students identify the missing sides and angles of right triangles. They use the rules of the Pythagorean Theorem to solve their problems.

Students explore weight. For this math lesson, students predict which item weighs more and discuss how they arrived at their decision. Students weigh several items to determine which weighs more.

Students sketch a design based on "The Night Chanter." In this art design lesson, students listen to the Native American prayer, "The Night Chanter" and illustrate their personal vision of the chant. Students critique the sketches and...

Ninth graders examine pollution problems and how it affects the community.  In this arctic cleanup lesson students study ocean currents and how they affect pollution. 

Students practice descriptive writing. In this unique writing lesson, students hear a story about a mitten. Then three grade levels come together to first, create a mitten on KidPix; second, describe the designed mitten; and third, try...

Students plot a hiking course using aerial photos and a topographic overlay and find the latitude and longitude of absolute locations. They measure the total distance of a hiked area and figure the area of the ground walked using Heron's...

High schoolers are introduced GIS systems and how they operate. Using a GIS system, they locate and map the various types of agricultural products grown in Oregon. They rank each county based on the amount of agricultural products...

Fifth graders examine some famous explorers who have helped to discover our country. They discuss explorers from three countries today. They are: Spain, Portugal, and England.

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

Students work in groups to research clocks and practice telling time. In this telling time lesson, students use the computer program ProQuest to study circles, including radius and diameter, and practice drawing circles using a compass....

Students identify the different tropical rainforests in the world using a map. In this ecology lesson, students describe the different methods of deforestation. They create a memo and present it to class.

Pupils 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 logs.

Seventh graders examine congruence postulates and apply knowledge to triangles in the world around them.

Middle schoolers 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...

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

Students create their own "weather" map using data from x-ray sources. They analyze and discuss why it is important to organize data in a fashion in which is easy to read. They compare and contrast different x-ray sources using a stellar...

Students explore the concept of fractal patterns. In 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...
