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
Lining Up Data
High schoolers examine the concept of function and make models of data and predictions based on that data.
Curated OER
Origami Cubes
Fourth graders use an origami design to make a set of cubes. Individually, they identify the characteristics of different quadrilaterals as they are folding the paper into cubes. To end the lesson, they make a new design with new...
