Students role-play as engineers designing wedge tools. They devise methods for shaping quarry rocks into pyramid blocks. Following a teacher demonstration, they use materials such as soap, clay, and foam for blocks and wood, plastic,...
Curated OER
Wheeling It In!
Students use everyday materials (milk cartons, water bottles, pencils, straws, candy) to build a small-scale transportation device that incorporates the wheel and axle and the lever. They race their carts/trucks, measure distance, time...
Curated OER
TE Activity: Pulley'ing Your Own Weight
Students experiment with common objects such as spools, string and soap to determine how pulleys make it easier to move large objects. They look at the difference between fixed and movable pulleys. They examine the many uses engineers...
Curated OER
You Must Still Think Yourself, CAS Can Only Help
Have the class learn about and make conjectures about a line intersecting a cubic. In this making conjectures about a line intersecting a cubic lesson plan, students draw lines that intersect a cubic at three different...
Texas Instraments
Angles in Circles
Teach your learners how to investigate the relationship between a central angle and an inscribed angle which subtend the same arc of a circle. The dynamic nature of Cabri Jr. provides opportunity for conjecture and verification.
Curated OER
Right Triangles
Learners classify triangles and make connections regarding angle measurements and attributes of acute, right, and obtuse triangles. They listen to teacher define and explain triangles. Everyone imagines a place where a broken wing for a...
Curated OER
Exterior and Interior Angles of Triangles
Tenth graders explore the exterior and interior angles of triangles. They use a theorem in order to prove a theorem about all polygons. Students use the theorem and its applications to find the angles of different types of triangles.
Curated OER
Introduction to Fractals: Geometric Fractals
Students explore the concept of fractals. In this fractals lesson, students discuss Sierpinski's Triangle using an applet. Students discuss the patterns involved with fractals. Students discuss the area of Sierpinski's triangle as the...
Curated OER
Fractals and the Chaos Game
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.
Curated OER
The Mandelbrot Set
Learners explore the concept of Mandelbrot sets and Julia sets. In this Mandelbrot and Julia set lesson, students use a function integrator applet to investigate two-variable function iterations. Learners use Julia set and Mandelbrot set...
