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 activity 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
Students 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
Learners use transformation to move the graph around. In this geometry lesson plan, 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. In this geometry lesson, students use picture to perform rotation, reflection and transformation. They identify the coordinate points of the new transformation.
Curated OER
Keeping in Shape
Third graders describe patterns in terms of reflection and rotation symmetry, and translations. They design and make a pattern which involves translation, reflection, or rotation. They demonstrate why a given tessellation covers the...

Radial Design Mandala
Students design original radial art designs.In this radial design instructional activity, students use compasses and a nature inspired idea to create radial art. Students understand the use of symmetry, balance and design shapes in...
Curated OER
Posters -- What's the Main Idea?
Young scholars 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...
Curated OER
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...
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
Young scholars investigate the influence of the Enlightenment on American society and government. In this Enlightenment lesson, students work cooperatively in groups to define the principles of the Enlightenment,...
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
Reflections over Two Lines & Dilations
Students create reflections over two lines. For 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 instructional activity, students discuss things artists use from nature then talk a walk to find some of the same things. Students look for...
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
Mum's Kitchen Floor
Students 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
Tessellating Art
Fourth graders create artwork showing their own unique tessellating shapes. They apply the symmetries of a regular polygon and describe the reflection or rotational symmetry of a figure or object. They share their art work with the class.
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.

Keeping Us in Stitches Activity: Appliqué Bedcover Design
Pupils explore patriotic and classical motifs in applique design and technique. A bedcover or quilt is produced using appropriate symmetry, color,proportion and composition.
