Lesson Exchange: Polygons (Middle, Mathematics)
Students discover the relationship between the sides of a polygon and the number of diagonals that can be drawn from one vertex, the number of triangles that those diagonals form, and the sum of the interior angles of that polygon.
Curated OER
Team Defense
Students communicate and work in team fashion on defense. They use correct rotations on defense against a fast break or undermanned situation. In addition, they practice footwork drills, triangle shifts and "Three on Two" drills to...
Curated OER
The Search for Pythagoras' Treasure
Students identify and define properties of triangles. In this geometry lesson, students identify the missing sides and angles of right triangles. They use the rules of the Pythagorean Theorem to solve their problems.
Curated OER
Running Colors
Students play a game with mats of different shapes and colors spread out over a playing area. As a shape and color is called out students run the the corresponding mat and stand on it.
Curated OER
Fractions and Paper Folding
Learners explore the concept of origami. In this origami instructional activity, students construct picture frames out of paper. Learners find the midpoint of the paper and determine the fractional area of the paper as it is folded.
Curated OER
Fractions
Students study fractions. In this art lesson, students fold paper, use origami, making new shapes and discuss the area of the shapes created.
Curated OER
The Geometry of Means
For this geometry worksheet, students are given a rectangle and a square. They verify ratios when given equal perimeters or areas. Students are given adjacent squares. They find the distance between the centers, and identify the means...
