Spaceship to Mars
Feel like a rocket scientist for the day. Using only paper and tape, scholars create a framework for a spaceship to Mars. Each sheet of paper costs $10 million and each piece of tape costs $100,000. Make sure you stay within budget!
Curated OER
Architecture is Elementary
Students learn the four orders of architecture: Doric, Ionic, Corinthian and Composite. They create their own 3d structure and work together in groups. They create basic geometric shapes. # Have fun learning about art history,...
Curated OER
Drawing Lines of Symmetry
Third graders explore the concept of symmetry using geometric shapes, capital letters and various other shapes. They fold shapes to show symmetry, draw lines of symmetry and create symmetrical designs.
Curated OER
Identify Polygons: Algebra/Geometry Institute
Eighth graders classify geometric figures. In this polygon lesson, 8th graders identify given geometric figures. They compare and contrast different polygons. Students name line segments, identify parallel lines, and interesections. ...
Curated OER
Symme"tree"
Students practice drawing lines of symmetry after the teacher draws shapes on the board. They create a class symme"tree" using only symmetrical shapes to decorate it.
Curated OER
That's So Square
Second graders are introduced to circles, triangles and parallelograms. As a class, they create the shape with their bodies and are shown the shapes in their actual size. To end the lesson plan, they sketch each shape and identify their...
Curated OER
Fold and Cut 2
Second graders make, name, and describe, using their own language and the language of geometry, everyday shapes and objects. They create and discuss geometric patterns which repeat (show translation), or which have rotational or...
Curated OER
Transformation
Third graders investigate symmetry by reflecting objects in different angles. In this geometrical transformation lesson plan, 3rd graders define the terms translation, rotation and reflection in order to physically turn geometric...

When A Line Meets Itself
Students investigate the linear characteristics of cultural art. In this art analysis lesson, students discover the Pre-Columbian Chimu culture and the many masks they created. Students identify the different shapes and lines in their...
Curated OER
Tangram Puzzles
Students explore the origin of tangram. In this algebra lesson, students form different shapes and figures using tangram. They solve for the area of different shapes without using any geometric formulas, but the idea of tangram being put...

Symmetry, Similar & Congruent Shapes
Fifth graders identify lines of symmetry., similar and congruent shapes. They use construction paper to create their own symmetrical shapes. Students create stained glass frames containing symmetrical, congruent and similar shapes.
Curated OER
Symmetry of Road Signs
Students identify symmetry in road signs. In this geometry lesson, students explore objects in the real world for symmetry. They perform translation, rotation and reflection.
Illustrative Mathematics
Placing a Fire Hydrant
Triangle centers and the segments that create them easily become an exercise in memorization, without the help of engaging applications like this lesson. Here the class investigates the measure of center that is equidistant to the three...
