Searching for Angles and Lines
Middle schoolers work to find and reinforce concepts related to lines and angles. They identify the characteristics of shapes that have one, two, and three dimensions. The students also work on definitions related to the geometry of shapes.

No Edge, No Center -- Exploring the Shape of Our Universe
Young scholars examine various "spaces" (including ones that are one-dimensional, two-dimensional, and three-dimensional). For each space, they will examine what it means to have or not have an edge, or to be finite or infinite.
Curated OER
Ship Shape
Third graders experiment with, identify, and follow teacher-directed instruction toward understanding two-dimensional geometric shapes found within the environment. Groups of students utilize geoboards to help them explain geometric shapes.
Curated OER
Solid Shapes
In this solid shapes activity, students learn to identify and solve word problems that use solid shapes. Students solve six word problems about solid shapes.
AIMS Education Foundation
Shifty Shapes
Shape shifters examine and experiment with pattern shapes. For this geometry lesson, they work in groups to name and describe pattern block shapes, and they discover the combinations of shapes that can be placed inside a hexagon.
Curated OER
Teaching Polygons using Technology
Third graders utilize different types of computer programs, such as Microsoft paint and Microsoft Word to study and create different types of polygons. They use PowerPoint to create a story about a shape and others that it meets during a...
Curated OER
Exploration with Geometric Solids
Students reinforce geometric concepts by playing "Guess My Solid." Through a process of elimination, they determine the shapes of mystery solids. Finally, students use various materials to construct their own geometric figures.
Curated OER
Shapely Figures
Middle schoolers are given magazines, scissors, glue, and one sheet of construction paper. They look for pictures showing real life representations of rectangular prisms, spheres, cones, and pyramids. Pupils cut out pictures showing each...
Think Map
Know Your Polygons!
Shape shifters recognize characteristics of polygons. Embracing language arts skills in addition to math, they use a thesaurus to pinpoint specific attributes of a set of polygons. They also participate in a 21-question guessing game...
Curated OER
Mobius Card- An Impossible shape
In this algebra worksheet, students solve word problems using linear equations and algebraic symbols. There is one problem with an answer key.
Curated OER
Create A Map!
Students examine two- and three-dimensional shapes, and discuss map skills and attributes. They plan and create their own school campus maps using pre-cut building site shapes.
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.
Curated OER
Math 212: Planes
In this planes worksheet, students consider the position of given vectors and find the vector equation of a plane. They identify the points that lie on a plane and determine the equation of a line through given points. This two-page...

Twisted Tangrams
Primary geometers create a picture using tangrams. In this geometry activity, students read Grandfather Tang: A Tale Told with Tangrams, cut out their own tangrams, and choose a character from the story to make using their tangram pieces.

To Canada with Love
Focus on line and color with a postcard project. Learners view various works of art and discuss line and color before moving on to creating their own work. Using nature as inspiration, pupils decorate postcards and mail them after...

Patterns and Fingerprints
Human fingerprint patterns are the result of layers of skin growing at different paces, thus causing the layers to pull on each other forming ridges. Here, groups of learners see how patterns and fingerprints assist scientists in a...
Illustrative Mathematics
Toilet Roll
Potty humor is always a big hit with the school-age crowd, and potty algebra takes this topic to a whole new level. Here the class develops a model that connects the dimensions (radii, paper thickness, and length of paper) of a...
Curated OER
Formulas for Volume and Surface Area
Students calculate the volume and surface area of each shape. For this geometry lesson, students use nets and other three dimensional polygons to create visuals of the volume of a shape. They define important vocabulary words...
Curated OER
2D Polygons and 3D Nets
Students compare and contrast two dimensional polygons and three dimentional nets by examining the differences in drawings. They create three dimensional shapes and label the faces, edges, and vertices. After creating the shapes, they...
Curated OER
A Cylinder and Its Net
Students sketch the nets for given polygons and cylinders. In this geometry lesson plan, students find the measurements that correspond with prisms, cones and cylinders. they identify parts of three-dimensional shapes.
Curated OER
Pyramids on Parade/Nets
Pupils sketch the shape of three dimensional pyramids using nets. In this geometry lesson, students differentiate a pyramid from other three dimensional shape. They define the attributes of pyramids.
Curated OER
Math: Symmetry and Similarity
Students describe the differences between congruence and similarity. After explaining the motions that indicate congruency of two shapes, they complete worksheets to draw lines of symmetry and similar shapes. With straws and twist...
Curated OER
Electronic Geometry Notebook
Pupils examine the relationship between two and three dimensional shapes. They use their drawings to solve problems. They create a notebook of the formulas and how they relate to the real world.
Curated OER
Bubbles Everywhere!
Eighth graders use concrete and graphic models to derive formulas for finding perimeter, area, surface area, circumference, and volume of two- and three-dimensional shapes. This lesson is a fun way to practice measurement and circle and...
