Pythagorean Theorem
Students investigate the properties and idea of the Pythagorean Theorem. In this algebra lesson, students identify the different parts of a right triangle and relate it to the Pythagorean Theorem. They do a robotic experiment to...
Curated OER
Transformations
Sixth graders discover transformations. In this graphing lesson plan, 6th graders explore visual examples of plotting transformations as they review translations, rotations, and reflections. Students also practice solving problems that...
Curated OER
Straight Graph Lines: Coordinates
Students access prior knowledge of coordinates. In this coordinates lesson, students graph coordinate points to create a symmetrical figure and of a straight line. Students complete several practice examples.
Curated OER
Heron's Formula
Learners use Heron's formula to calculate the area of a triangle. In this geometry lesson, students use three different methods to solve the area of a triangle. They find and construct the incentor and angle bisector of a triangle.
Curated OER
Trigonometric Ratios
Students measure and analyze angles. In this trigonometry lesson, students measure angles and distances use non-traditional techniques. They identify the different ratios of sine, cosine and tangent.
Curated OER
Extending Geometric and Numeric Patterns
Students study patterns. They construct growing patterns using pattern blocks and isosceles right triangles. They verbally describe the patterns and state the rule that describes the relationship involving the number of pattern blocks...
Curated OER
Tilings with Multiple Symmetries
Students explore how some tilings can display rotational and/or reflection symmetry in addition to translational symmetry. Students demonstrate how these tilings can be generated using either one of the symmetry concepts and Zome System...
