Curated OER
Lines of Symmetry
Fourth graders demonstrate lines of symmetry using polygons, pentominoes, and block letters of the alphabet. They describe, identify, and analyze characteristics and properties of geometric shapes.
Curated OER
Fold and Cut
Second graders explore line symmetry and the names and attributes of two-dimensional mathematical shapes. They study the context by folding and cutting out shapes to make a series of mathematical shapes.
Curated OER
Six Squares
Students create different shapes on grid paper. In this two-dimensional geometry lesson plan, students take turns outlining a shape made of six squares on the graph paper. They identify all shapes they see once everyone has had a turn.
Curated OER
Ecology - Biodiversity Lab
Studnents examine the degree of biodiversity that exists in one's everyday environment, in order to develop an understanding of how scientists classify organisms and to explain why biodiversity is important for living things.
Curated OER
Creating Tessellations
Third graders explore the history of tessellations; then use art and geometry to create an original tessellation.
Curated OER
Making Shapes
Tenth graders construct geometric figures using compasses and protractors.
Curated OER
Seeing Double
Students develop an intuitive definition for symmetry after viewing a PBS video. They examine asymmetrical patterns and demonstrate their knowledge by changing them to symmytrical.
Curated OER
Pattern Matching
First graders examine how to determine the lines of symmetry in pictures, shapes, and patterns by completing the lessons in this unit. They make patterns that show a line of symmetry and describe it using their own language.
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
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
Congruent figures
In this congruency worksheet, learners complete problems dealing with congruent and non-congruent figures. Students complete 5 short answer and multiple choice problems.
Curated OER
Congruence Activity
In this congruency worksheet, 5th graders complete 4 questions about congruent figures and transformations. Page has links to additional activities.
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 students calculate altitude of their flying kites using a formula.
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
Geometry Scavenger Hunt
Learners use the digital camera, identify geometric shapes (in nature as well as man-made), and gain a better understanding of geometric vocabulary. They search for and recognize geometric shapes in unusual settings
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
Lots of Squares
Pupils work in pairs, to make a square on the geoboards with a rubber band (or draw one on the dot paper). It can be any size and in any location and share their answers with the class.
Curated OER
Symmetry In Nature
Students investigate the symmetry that is found in nature. They view shapes and patterns in nature while looking at images. Students look for tessellations while obtaining photographs with a digital camera. The information is used for...
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
Area of Parallelograms
Seventh graders review the process of finding the area of a rectangle and complete a couple of examples as a class. They discuss what a parallelogram is and what the formula would be for finding its area. They listen to an explanation...
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.
