Irregular Fractals
Students study and research irregular fractals and construct a few based on their research. Students practice pattern recognition skills and plane geometry skills calculating dimensions on the Fractured Pictures activity.
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
Tangram Perimeters
Students work together to make figures out of tangram squares. In groups, they calculate the measurements they need and apply the Pythagorean Theorem. They complete a worksheet solving equations using the theorem and review their answers.

France
Eighth graders visit two websites about France in order to take a virtual trip of France. They answer specific questions about France and state the similarities and differences between France and the U.S.
Curated OER
Hexagoning the Circle
Students explore similarity to see that the area of a circle should be a constant times the square of its radius. Students create a hexagon. Students share their designs with the class.
Curated OER
The Workers
Students observe the axis of a graph on the board and add the title and axis labels. They plot two points on the graph and join the two with a line and work to describe the story in each of the graphs.
Curated OER
Lesson Plan for Fontana Mines
Students estimate and compute with rational numbers. They compare, order and convert among fractions, decimals and percents. Students analyze problems to determine if there is sufficient or extraneous data to solve.
