Curated OER
Looking For Triangles
Students solve problems with triangles. In this geometry lesson plan, students analyze shapes to find different triangles. They name the shapes created by putting triangles together.
Curated OER
Constructing a Wardrobe
Sixth graders compare and contrast storage spaces of the past and present. They examine how furniture tells us how people lived, and work in pairs to design and construct a contemporary wardrobe that fits their personal needs.
Curated OER
Translating Transformations in Geometry
Students create an image using given coordinates and evaluate how the coordinates change when a slide or rotation takes place.
Curated OER
Function Tables
Students practice representing problems found in the real world in terms that can be translated into mathematical expressions. The situations are represented in tables and graphs by students.
Curated OER
The Mandelbrot Set
Students 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.
Curated OER
Hurricane Tracking
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...
Curated OER
Investing
Students collect data on investments and draw conclusions. For this algebra lesson, students analyze exponential graphs as they relate to money. They discuss the cause of an account balance being high or low.
Curated OER
Moving Straight Ahead
Students analyze the relationship between speed, time and distance. In this math lesson, students plan a school trip. Students determine the efficiency and cost effectiveness of a trip.
Curated OER
Tangram Tantrums
Pupils discuss tangram vocabulary, and act out slide, flip, and turn. They observe tangram puzzles on a web page, and solve their own tangram puzzles.
Curated OER
Fractals Rock: Investing the Fractal Tree
Students investigate the relationship between fractals and sequences. In this geometry lesson, students build a fractal tree. They investigate different career fields where fractals are used in the real world.
Curated OER
The Mandelbrot Set
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.
Curated OER
Poppy Meets Pythagoras
Eighth graders find connections between numbers in a table; use Pythagoras' theorem in a general algebraic form; and measure accurately from a scale drawing to find a method that might enable the helicopter to land inside a rectangular...
Curated OER
Pythagorean Theorem Investigation
Eighth graders investigate the Pythagorean Theorem and practice applying the theorem to various triangles. Finally, in the next lesson in the sequence, 8th graders create a song or a story to help them remember the Pythagorean Theorem.
Curated OER
Impossible Graphs
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
