Curated OER
Introduction to Fractals: Infinity, Self-Similarity and Recursion
Students think about several of the concepts from fractals, including recursion and self similarity. They use mathematical concepts of line segments, perimeter, area and infinity are used, and skill at pattern recognition is practiced.
Curated OER
Slope of a Function
Seventh graders explore the concept of the slope of a line. They see how to determine the direction of the line. Also students are introduced to the slope intercept algebraic expression in conjunction with the rise/run.
Curated OER
Symmetry
Learners identify the different symmetry in polygons. In this geometry lesson, students identify line, rotational and point symmetry in different objects. They find the symmetry with 90% accuracy.
Curated OER
Indirect Euclidean Proofs
In this Euclidean proofs worksheet, 10th graders solve 10 different problems that include completing indirect Euclidean proofs. First, they write a statement for each of the reasons listed on the sheet of proofs. Then, students solve the...
Curated OER
Reflections
Students investigate image and pre-image. In this geometry lesson plan, students identify the reflection and rotation of different shape on a coordinate plane. They identify similarities and differences of image and pre-image of a...
Curated OER
Introduction to Locus
Students define the five rules of loci. In this geometry lesson, students identify the locus of points that creates a circle. They calculate the distance from a fixed line and point.
Curated OER
Drawing a Perspective Floor
Tenth graders investigate the three D world of building. For this geometry lesson, 10th graders investigate math as it relates to the real world, increasing their perspective on mathematical concepts. They realize there is more to math...
Curated OER
Symmetry in Kaleidoscope Designs
Students define reflection, rotation and symmetry. In this symmetry lesson, students move the graph around the coordinate plane and identify the line of symmetry. They identify the different designs of a kaleidoscope.
Curated OER
Light Bounce
Students solve problems involving triangles. In this geometry lesson, students apply properties of triangles to find the missing angles and sides. They identify angles of parallel lines cut by a transversal.
Curated OER
Diagonals to Quadrilaterals II
Students identify the properties of different polygons. In this geometry lesson, students find the slope of a line and calculate the distance between two lines. They differentiate between similar and congruent polygons.
Curated OER
Pushing Pivots
Students calculate the area and diameter length of a circle. For this geometry lesson, students investigate the use of pivots as they review parts of a circle. They create a circle using cardboard and label all the parts.
Curated OER
What's Your Design?
Sixth grade students: design a stained glass window, submitting their initial plan detailing the measurements of all lines and angles. Seventh grade students: create a scale drawing of their own geometric family of four members.
Curated OER
Polygon Perimeters
Students define the terms polygon and perimeter to begin the lesson. Using a calculator, they practice determining the perimeter of various symbols in a painting. They discuss how geometry and art are related to one another.
Curated OER
The Isosceles Triangle Problem
In this geometry worksheet, 10th graders solve a problem involving an isosceles triangle. The problem appears to be deceptively easy, but instead requires the use of trigonometry to arrive at a correct solution. The one page worksheet...
Curated OER
Strongest Polygon
High schoolers define and identify shapes by name. In this geometry lesson plan, students construct, identify and compare polygons based on the number of sides. They classify each shape based on their angle sum theorem.
Curated OER
Speedy Area
Students calculate the speed, rate and distance. In this geometry lesson, students calculate the area and perimeter of polygons. They perform an activity with a CEENBoT and calculate the distance and speed.
