Tessellation Sensation
Geometers investigate patterns and symmetry, and examine the artwork of M.C. Escher on the Internet. They compare his style to the floor and ceiling tiles in the classroom. If you have ImageBlender™ software, you could have your class...

Let the Matrix Do It
Students create a matrix of the vertices of a triangle and produce new matrices that dilate, translate, rotate, and reflect the original triangle. After multiplying each matrix by a new scale factor, they graph the new matrix and...

Transformers
Students use transformation to move the graph around. In this geometry lesson, students observe transformation of symmetry groups. They use the TI to move the sides of the polygons around and make predictions.
Curated OER
Mirror Tool
Students define properties of polygons. In this geometry lesson, students differentiate between similar and congruent polygons. They identify and use the properties of solids to solve problems.

Mum's Kitchen Floor
Learners discuss patterns on a chess board examining symmetries. They read the problem and then brainstorm for ways to solve the problem. As they complete the floor pattern, they record symmetries that it contains.
Curated OER
Noughts
Students try to figure out the strategies to the game Noughts. Students logic must play a part in the process of the game. Students apply the symmetries of regular polygons. Students devise ways to critically follow a chain of reasoning.
Curated OER
Ge-Oh Boy, Oh Boy
Students listen to the book, Sam Johnson and the Blue Ribbon Quilt and discuss the art of quilting. They examine various symmetrical sewing designs, and identify reflection pieces, slides, and flips.

Geo Jammin By Design: The Important Thing
Students brainstorm what they know about geometric terms and patterns. They identify symmetry, shapes and congruency. They create a book of symmetry.
Curated OER
Geometry Level 3
What a wonderful resource! Learners create two-dimensional shapes according to the instructions stated, use the squares to make a triangular prism, a cube, and a pyramid, and identify features of plane shapes, among a myriad of other...

Addition and Subtraction Formulas 2
Knowing the addition formulas allows for the calculations of double and half formulas. The fourth installment of 16 has the class use the addition formula to develop the double angle trigonometric formulas. Using the double formula,...
Curated OER
Fractals
Students explore the concept of fractals. In this fractal lesson plan, students use applets to explore Koch's Snowflake, Sierpinski's Triangle, and other fractals. Students develop these concepts through exploration and teacher guided...

More No-Three-In-A-Line
Fourth graders read Mary's problem and make sure that they examine it.
After some discussion, let the class work on the problem in their groups.
They then take turns in putting a picture of their arrangement on the board.
Curated OER
Classifying Functions
Eleventh graders sort different types of functions including rational, periodic, exponential, polynomial, quadratic, logarithmic and linear using "function cards." The functions are displayed in multiple representations including...
Curated OER
Tessellations
Fifth graders investigate the relationship between math and art by examining patterns and polygons.They examine how polygons make up the patterns that form tessellations, and determine tessellations that occur in nature. Finally, they...
Curated OER
Fitness
Fourth graders determine how to design regular and semi-regular tessellations of the plane. They develop the ability to demonstrate why a tessellation covers the plane in this series of lessons.

Geo Jammin' By DeSign - Day 1, Lesson 1: Math in Motion
Second graders, through large screen monitor, study geometric design. They participate in a diagnostic assessment in which they use pnecils, scissors and paste.
Curated OER
The Delta Flier
Students make calculations in order to construct a kite in the shape of an isosceles right triangle. In this kite lesson plan students calculate altitude of their flying kites using a formula.
Curated OER
Transforming Triangles
Sixth graders examine how to graph translations (slides) and reflections (flips) on a coordinate plane. They practice the slides and flips kinesthetically and apply it to a worksheet working with triangles.
Curated OER
Spice Up the Basal
Fifth graders study English reading and writing skills as they participate in exciting interdisciplinary hands-on activities using a basal reading series.
Curated OER
ART- LANGUAGE OF SYMBOLS
Students discuss how color construct meaning in art. They will demonstrate a technical knowledge and creative use of formal elements and principals of design. Students then discuss the way their selection of color contributed to their work.
