Learners use the axes and measure angle tool to explore and calculate complementary angles with Cabri Jr. They also identify what happens to the calculation as they drag the endpoint into a different quadrant. Finally, they label each...

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,...

Students explore the concept of fractals. In this fractal lesson, students use applets to explore Koch's Snowflake, Sierpinski's Triangle, and other fractals. Students develop these concepts through exploration and teacher guided...

Young scholars make bread and understand that bread gives us energy. In this bread lesson plan, students read the story A Trip to the Market, and learn about the importance of bread. Then they make the bread!

Students measure using tools they have made. In this algebra lesson, students measure the height and distance using non-traditional measuring methods. They apply their findings to algebra and trigonometry properties of measurements.

First graders explore geometric shapes. In this math lesson, 1st graders sort shapes into groups and discuss the characteristics of the shapes. Students build geometric shapes using toothpicks and marshmallows.

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 solve problems using patterns. In this algebra lesson, students identify the relation, domain and range of a function. They graph functions using coordinate pairs.

Pupils 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

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 find the perimeter and area of circles, triangles, and rectangles. In this perimeter and area lesson plan, the teacher gives students formulas for each shape and measurement and works through examples on the board. While no...

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

Students calculate the area of triangles using a variety of materials including computer applets.

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 watch and discuss an M. C. Escher video, use what they have learned to explain and apply their knowledge of tessellations in order to create a slide translation, present their findings in a 12" x 18" poster, and explore...

Students investigate the supposed traveling path of a meteorite. They use sound in order to triangulate the path. The results of the experiment are written on a map to display the path of the meteorite. The culminating activity is when...

Learners design and build their own truss. In this physics lesson, students calculate the forces and maximum load. They complete a full scale diagram of their design.

Students study geometric shapes, lines, and the primary colors as they create Mondrian-like art prints.

Sixth graders explore different geographic relationships in like drawing lines, rays, and parallelograms. This instructional activity could be used for review because it covers more than one concept. The students should have prior...

Students work together with a partnet to design a building. Using materials, they create the inside and outside of the structure along with works of art. They present their creation to the class and receive constructive criticism in return.

Sixth graders explore symmetry and discuss the difference between a rotation and reflection. Using hands-on activities, such as folding paper shapes, they discover how to find the lines of symmetry and symmetrical characteristics. As a...

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.

Learners use CERES percent coverage surface data with a world map in locating landmasses and bodies of water at Earth's Equator.

Students discover that four special segments have a common intersection point. They identify the position of the intersection point in triangles. They produce conjectures about areas of the divided triangles.
