CK-12 Middle School Math Concepts - Grade 6
Twelve chapters cover a multitude of math concepts found in the Common Core standards for sixth grade. Each title provides a brief explanation of what you will find inside the chapter—concepts from which you can click on and learn more...
Curated OER
Congruent Segments
The task, should your class decide to take it, is to list a series of reflections that transfer a line segment from one position to another.
Curated OER
Geometric Transformations
Learners examine images and preimages of a mapping and identify isometry. They view images by M.C. Escher, observe teacher demonstrations, and create a translation image, a rotation image, and a dilation.
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.
Illustrative Mathematics
Reflections and Isosceles Triangles
Geometers explore symmetries of isosceles triangles by using rigid transformations of the plane. They complete four tasks, including congruence proofs, which illustrate the relationship between congruence and rigid transformations. The...
Curated OER
Invertebrate Phyla
Students explore the invertebrate phyla. They discuss the characteristics of the invertebrate Phyla in the Kingdom Animal. Students classify organisms into Phyla based on their characteristics. They distinguish radial symmetry, bilateral...
Curated OER
Introduction to Fractals: Infinity, Self-Similarity and Recursion.
This lesson introduces high schoolers to the ideas involved in understanding fractals. They develop a sense of infinity, self-similarity and recursion and
Curated OER
Graphs of Quadratic Functions Section 11.6
In this graphing worksheet, learners graph quadratic functions. They identify the maximum and minimum value of the function, determine the line of symmetry, and locate the vertex. Coordinate planes are provided for each function. There...
Curated OER
Mine Is! Is Yours?
First graders engage in a lesson which teaches the concept of symmetry through the use of letters in the student's name. They use a piece of yarn to see if they can make symmetrical pieces out of their own names.
Curated OER
Magnificent Mandalas
Students examine the principle of radial symmetry and apply it to an original mandala design. They draw a design using organic and geometric shapes, repeating the design symmetrically around the paper.

Peace Quilt
Learners explore color, shape, line, balance, radial symmetry, unity, repetition, and pattern as they make a peace quilt inspired by those made by Hawaiian women in the 1800s. After learning a bit about the history or peace quilts, the...
Curated OER
Angles Activities
A series of geometry worksheets have mathematicians constructing, dissecting, overlapping, and measuring as they analyze angles in various contexts. Learners use symmetry and reflections in a compass rose to write instructions on...
Sargent Art
Color Value Study
I love geometric art because it applies mathematical reasoning to an artistic endeavor. Creative kids use scale values to highlight their complex, repetitive, geometric designs. Symmetry, angles, and congruence are three concepts that...
Hawaiʻi State Department of Education
Gargoyles Galore
Grrrrr, gargoyles are on the loose! Young artists are familiarized with the history of gargoyles, examine pictures of them, and hear a story about them. Then, they draw a gargoyle and write down exactly how they did it (procedural...
Curated OER
A Different Point of View
Elementary schoolers utilize a pattern worksheet embedded in this plan to work on a deeper understanding of geometric concepts like symmetry and congruency. Since geometry is such a visual form of mathematics, this lesson should fit...
Curated OER
Logo Licenses
Third graders find all the lines of reflection symmetry in a given shape, identify the order of rotational symmetry of a given shape. They create designs which have reflection symmetry, rotational symmetry (orders 2, 3, 4, 6) and...
Curated OER
Math/Technology: Symmetry
Fourth graders, using KidPix, use stamps and pencil tools to illustrate which pictures have symmetry. They add text boxes to explain their answers in math terms. Students practice skills in rotation, reflection, and translation on an...
Curated OER
THE MEAN INDEX CARD
Students cut an index card to create three similar right triangles and explore the congruencies and proportions that exist. They investigate the properties of lines and concepts of congruency, similarity, tangency and symmetry of...
Curated OER
Technology Integrated Lesson
Students investigate symmetry in the real world. In this geometry lesson, students inter-relate math and technology. They create and name a variety of polygons.
Curated OER
Glide Reflections
In this glide reflection worksheet, students draw and answer questions about reflections of different shapes. Students answer 5 questions.
Curated OER
Tantalizing Tangrams: What Are Transformations?
Students use the Internet to learn about transformations and tessellations. In this geometry lesson, students use the Internet to define the meaning of reflections, translations, rotations, glide reflection and symmetry. Students...
Curated OER
Two Triangles' Area
Need an activity for teaching the Pythagorean Theorem? Geometry juniors apply the Pythagorean theorem to two triangles to determine a final calculation.
Curated OER
Transformational Geometry Using the Geometer's Sketchpad
Students complete a webquest on the various types of symmetry. Using a computer, they explore the concepts of transformational geometry and identify points, segments, lines and planes. They experiment with the rotation of a quadrilateral...
Curated OER
Shapes Are Everywhere
Third graders explore pattern blocks noticing their similarities and differences and share their observations with others. They classify shapes by discussing sides and angles and combine pieces to make new shapes.
