Angles in Circles
Teach your learners how to investigate the relationship between a central angle and an inscribed angle which subtend the same arc of a circle. The dynamic nature of Cabri Jr. provides opportunity for conjecture and verification.
Curated OER
Angle Exploration and Classification
Students compare and contrast angles and identify them as acute, obtuse, right, or straight angles. They create rays and angles using uncooked spaghetti, read and discuss key vocabulary terms, and complete a variety of geometry worksheets.

A Geometry Worksheet - Similar Triangles
In this similar triangles activity, students find the scale factor of 6 sets of similar triangles. Students find the scale factor of two similar triangles given a sketch with measurements. Students use proportions to find a missing side...
Curated OER
Black Hole...Fade-out!
In this black hole worksheet, students read about how images fade to black when they reach an event horizon of a black hole. Students solve 3 problems about black holes using a given equation for luminosity. They find the time it takes...
Curated OER
New York State Standards
In this math worksheet, students review for the high school exit exam of New York. They solve problems using algebra, geometry, and precalculus. There are 30 questions.
Curated OER
Graphic Designing with Transformed Functions
Teach your class how to transform a graph! By identifying the domain and range of the functions, high schoolers can observe the parabola and find the vertex of the transformed graph.
Curated OER
Determine the Coordinate of Transformations
Learners investigate transformation on a coordinate plane. In this geometry lesson, students identify pairs of coordinates and their location on the grid. They perform rotation and reflection of each polygon.
Curated OER
Quilt Squares
Young scholars research the history of the quilt in American History and view a PowerPoint Presentation. They create a quilt square with colored paper using polygons, transformations, rotations, and reflections on the computer and on a...
Curated OER
CONCEPTS IN NUMBER THEORY.
Students study the Maya culture and their achievements in mathematics, how bacteria grow exponentially, use rational numbers to convert back and forth between Celsius and degrees Fahrenheit, how some architectural designs are examples of...
Curated OER
Transformations and Translations
In this transformations/translation worksheet, students draw transformations based on shapes and vectors of given translations. A reference web site is given for additional activities.
Curated OER
Effect of Transformations on Coordinates
In this effect of transformations on coordinates worksheet, students determine the coordinates of 4 geometric shapes on a grid after a given transformation.
Curated OER
Triangle Tango: Special Right Triangles
Young scholars investigate properties of special right triangles. In this geometry lesson, students use the Pythagorean Theorem to solve for missing angles and sides. They perform reflections.
Curated OER
Data Representation
Students solve real life scenarios using math. For this geometry lesson, students collect, predict and interpret data. They measure a chair using different measurements and choose what would make the chair the best design.
Curated OER
Cracks on the Walls
Students observe the cracks in school walls and pavements. In this geometry lesson, students explore the factors to be considered before building a structure. They complete a graphing and calculation worksheet after the lesson.
Curated OER
Geometry Scavenger Hunt
Learners use the digital camera, identify geometric shapes (in nature as well as man-made), and gain a better understanding of geometric vocabulary. They search for and recognize geometric shapes in unusual settings
