Curated OER
Testing For Congruent Triangles
Students define and discuss congruency and the corresponding parts between congruent triangles. They create a pair of congruent triangles, test for congruency, and complete a worksheet.
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.

Irregular Fractals
High schoolers explore the concept of irregular fractals. In this irregular fractals lesson, students discuss how to find fractal dimensions through teacher led discussion. High schoolers calculate fractal dimensions of various fractals.
Curated OER
Patterns In Fractals
Middle schoolers find number patterns in the generation of several different types of fractals.
Curated OER
Lines, Rays, Line Segments, and Planes
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

Patterns in Fractals
Learners explore the concept of fractal patterns. For this fractal pattern lesson, students use an applet about the Hilbert Curve to answer questions about rectangles and other polygons. Learners derive the fractal pattern when dividing...
Curated OER
Angles Lesson Plan
Students stud angles, and then play the "What's Your Angle?" game. They complete at least 10 computer generated problems from the Angles Applet.

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...
