Inductive Reasoning
In this algebra instructional activity, 10th graders apply inductive reasoning as they figure out the next number in the sequence or pattern. There are 53 problems.
Curated OER
Classifying Transformations
Pupils analyze different polygons by shapes and sides. For this geometry lesson, students differentiate between similar and congruent polygons. They name the different polygons based on the number of sides.
Curated OER
Reflections
Students investigate image and pre-image. In this geometry lesson, 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 reflection.
Curated OER
What You See Is Not Always What You Get!
Students estimate and calculate the distance of a shape. In this algebra lesson, students differentiate between a horizontal distance and it's reflected image. They measure the reflection and the point starting at the eye of the observer.

"The Greedy Triangle" by Marilyn Burns
Learners discover which regular polygons can be used to tile a plane.
Curated OER
Three Dimensional Figures
In this geometry activity, students draw different views, describe patterns, count units, and answer short answer questions with shapes containing cubes. This activity would be an excellent homework assignment.
Curated OER
Lesson Exchange: Polygons (Middle, Mathematics)
Pupils 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
Mathematics in Art?
Fifth graders view prints of M.C. Escher's work. They look at examples of geometric figures and polygons and discuss places they have seen them. Students create their own tessellations. They write a report about the process they used in...
Curated OER
Irregular Fractals
Middle schoolers study and research irregular fractals and construct a few based on their research. Students practice pattern recognition skills and plane geometry skills calculating dimensions on the Fractured Pictures activity.
Curated OER
Mondrian, Math, and Amazing Colors
Students study geometric shapes, lines, and the primary colors as they create Mondrian-like art prints.
Curated OER
Looking For Triangles
Students solve problems with triangles. In this geometry lesson, students analyze shapes to find different triangles. They name the shapes created by putting triangles together.
Curated OER
Symmetry In Nature
Students investigate the symmetry that is found in nature. They view shapes and patterns in nature while looking at images. Students look for tessellations while obtaining photographs with a digital camera. The information is used for...
Curated OER
Tangrams
Students construct the tangram pieces from a square paper by following directions to fold and cut. They make observations on the pieces formed and compare how they are related to each other. They explore patterns and shapes with the...

"How Many Snails?" by Robert Wells
Middle schoolers represent algebraic patterns in various ways.
Curated OER
Copycats
Third graders describe the features of 2 and 3 dimensional objects and use the language of geometry. They design and make a pattern which involves translation, reflection or rotation.
