Curated OER
Slides, Flips and Turns
Third graders are introduced to different types of transformations. As a class, they describe how a stuffed animal slides across the floor and use themselves to demonstrate as well. Individually, they flip and turn in different...
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...

Identifying Series and Determining Congruence or Similarity
Learners consider a set of questions to determine a series of transformations that will move one figure to another. Once the series is determined, the pupil then determines whether the pre-image and image are either congruent or similar.
Curated OER
Transformations Using the Geometer's Sketchpad
Learners discover rules for single transformations, rules for composition of transformations, when a figure has transformation symmetry, and if a transformation is congruent to its preimage.
Curated OER
Spice Up the Basal
Fifth graders study English reading and writing skills as they participate in exciting interdisciplinary hands-on activities using a basal reading series.
Curated OER
Geometry Level 3
What a wonderful resource! Learners create two-dimensional shapes according to the instructions stated, use the squares to make a triangular prism, a cube, and a pyramid, and identify features of plane shapes, among a myriad of other...
Curated OER
The Geometry of Paul Goble's Artwork
Students examine the concepts of geometry used by Paul Goble in his book Adopted By The Eagles. After analyzing Mr. Goble's work they create an original piece featuring symmetry, pattern, repetition, and other principles of geometry....
Mathematics Vision Project
Geometric Figures
Logical thinking is at the forefront of this jam-packed lesson, with young mathematicians not only investigating geometric concepts but also how they "know what they know". Through each activity and worksheet, learners wrestle with...
Bytes Arithmetic
Geometry Pad+
Graphing paper, pencil, ruler, protractor, and compass, all get replaced or supplemented with this dynamic geometry application. Here, you can create, move, and scale many different shapes, as well as, explore and change their properties...
Curated OER
Symmetries in Quadrilateral Tilings
Students analyze symmetries of quadrilateral tilings and discover how various types of symmetries, used alone or in combination, can generate the same pattern in more than one way.

Geo Jammin' By DeSign - Day 1, Lesson 2: Dancing Duo
Second graders and teachers identify geometric vocabulary word by searching a geometry website. They create a Quilt Word Wall using the geometry words.
Curated OER
Exploring the Properties of Rectangular Prisms.
Students define properties of rectangular prisms. For this geometry lesson, students identify the relationship between two and three dimensional objects. They use Cabri technology to graph their figures.
Curated OER
Exploring Properties of Rectangular Prisms
Students explore the properties of rectangular prisms. In this geometry instructional activity, students identify properties of two and three dimensional shapes. They use Cabri technology to create polygons and solve problems.
Curated OER
Powerful Polygons
Students scan the classroom to find different common shapes. They listen as the teacher defines polygon and regular polygon. The teacher demonstrates regular polygons via the Internet and the "Math is Fun" web site. Students go outside...
