Factoring Trinomials Using Tiles
What's the opposite of multiplying binomials? Learners apply their previous knowledge of multiplying binomials using algebra tiles to factor trinomials. The lesson plan introduces factoring as a process that uses algebra tiles to...
Curated OER
Reflections
Students investigate the concept of reflectons. They investigate how an image has a reflection that is symmetrical. They also choose household objects in order to have real life application for finding lines of symmetry.

Geo Jammin' By DeSign - Day 5, Lesson 24: Read All About It!
Students listen to The Important Thing About Quilt Design and rewrite an original version using geometric terms.
Curated OER
Translations, Reflections, and Rotations
Learners are introduced to the concepts of translation, reflection, and rotation. They practice translating, reflecting, and rotating two-dimensional objects on the coordinate plane. students use computers to learn about the three concepts.
Creative Educator
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...
Curated OER
Transformers
Pupils 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
Transformation Trio
Students identify the transformation and rotation of polygons. For this geometry lesson, students use picture to perform rotation, reflection and transformation. They identify the coordinate points of the new transformation.
Curated OER
Radial Design Mandala
Students design original radial art designs.In this radial design lesson, students use compasses and a nature inspired idea to create radial art. Students understand the use of symmetry, balance and design shapes in continual patterns....
Curated OER
Posters -- What's the Main Idea?
Students discuss the basics of poster productions. In groups, they follow written directions to make a poster about asthma, allergies, AIDS, or personal safety. They present their poster to the class and reflect on the process in a journal.
Curated OER
Let the Matrix Do It
Pupils 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 describe...
Curated OER
Geometric Transformations
Students solve problems involving transformations of geometric figures. They review graphing points in the coordinate plain, plot points and connect to create a triangle. Then, they reflect triangles over the x and y axis and use...
Curated OER
If These Walls Could Talk
Students investigate the influence of the Enlightenment on American society and government. For this Enlightenment lesson, students work cooperatively in groups to define the principles of the Enlightenment, American...
Curated OER
Frieze Patterns
In this frieze pattern instructional activity, students draw frieze patterns that can be constructed from a given motif. They perform translations, glide reflections, horizontal and vertical reflections and 180 degree rotations. This...
Curated OER
Terrific Tessellations
Students explore tessellations that are found in nature and everyday objects. They observe the works of M.C. Escher. Students create their own tessellations using pencil and paper.
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.
Curated OER
Chapter 8 Vocabulary: Geometry
In this vocabulary worksheet, students match the vocabulary word to its proper definition. They identify words such as symmetry, scale factor, coordinate plane, rotation, reflection, and translation.
Curated OER
Reflections over Two Lines & Dilations
Students create reflections over two lines. In this reflections worksheet, students compare and contrast reflections over parallel and intersecting lines. They dilate figures and investigate the effect of the dilation using measurement...
Curated OER
Nature Walk
Students explore nature artists and participate in a nature walk. In this art/nature lesson plan, students discuss things artists use from nature then talk a walk to find some of the same things. Students look for different...
Curated OER
Signal Flags
Students examine the use of signal flags on vessels. They use measurements and symmetry to create their very own signal flag. Students work together and as individuals to solve problems and express their ideas.
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.
Curated OER
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
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
Keeping Us in Stitches Activity: Appliqué Bedcover Design
Students explore patriotic and classical motifs in applique design and technique. A bedcover or quilt is produced using appropriate symmetry, color,proportion and composition.
Curated OER
Artists, Architects, and Architecture
Students are introduced to the concept of architecture and how it has changed over time. In groups, they discuss how the places people have built reflects their values and needs. They use the internet to research the history of...
