Curated OER
Geometry in Art
Students examine mathematical symbols and formulas included in works of art. They analyze quilts for shapes and they each make their own quilt from squares using geometric shapes.
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
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
How Tall Is That Flag Pole?
Students examine various triangles and discuss how similar triangles have sides that are proportional. They utilize an ancient Egyptian method to determine the height of a flagpole.
Curated OER
Learning about Shapes with Tangrams and the Net
Students use tangrams, student literature, and Websites to explore shapes.
Curated OER
Similar and Congruent Triangles
Students create and classify different types of triangles using an online geo-board. They explore the concepts of similar and congruent as they discover how to draw similar and congruent triangles.
Curated OER
Creating Tessellations
Third graders explore the history of tessellations; then use art and geometry to create an original tessellation.
Curated OER
Geometry Geopardy
Third graders participate in a game in order to review geometric concepts.
Curated OER
Patterns: A Stitch in Time
Students recognize shapes, designs and numbers that form patterns. Using their surroundings, they identify common patterns. They create their own patterns in various software programs and share them with the class.
Curated OER
Strawberry and Chocolate Milk
Pupils listen to the math problem and discuss. They work alone or in groups to come up with the possible solutions and put their pictures of the bottle arrangements on the wall so that the class can refer to them.
Curated OER
Transformation: Reflection
Tenth graders identify and analyze appropriate key vocabulary terms associated with transformations and reflection. Students experience creating and recognizing reflection with hands-on manipulations. Students discover real-world...
Curated OER
Algebraic Transformations
Students create a shape sorter and consider all possible moves that will return a shape to its original position. They investigate the results when two of these moves are performed consecutively, to learn about the commutative and...
Curated OER
Data Representation
Students solve real life scenarios using math. For this geometry lesson, students collect, predict and interpret data. They measure a chair using different measurements and choose what would make the chair the best design.
Curated OER
Geo-Folder
Second graders create a Geo-Folder based on geometric terms and concepts. They make a Table of Contents that guides them through the process of assembling a folder of completed activities.
Curated OER
Figure This
Second graders identify congruent figures and match shapes using transformation. They work in groups, utilizing a worksheet imbedded in this plan to gain practice identifying congruent shapes.
Curated OER
Strawberry Milk
Young scholars work in groups or alone to solve the problem. They use a systematic approach to get all possible answers. They report back to the class with solutions. They may extend their studying using a crate with room for 9 bottles.
Curated OER
Tessellation Quilt Squares
Fifth graders design a "quilt block" that has a tessellating pattern to help create a class tessellation quilt. They describe relationships between two- and three-dimensional shapes and analyze attributes and properties of geometric...
Curated OER
Absolute Value of Linear Functions
Students discover how abolute value affects linear functions. They complete a worksheet simulating a path for miniature golf hole in one for three figures. They construct a hole in one graph for each hole marking the X and Y coordinates.
