Shapes at Work
Students use their classroom to look for various types of shapes. In their science journals, they record the shapes they find and identify those that can be used to solve problems or build structures. They share and post their sketches...
Curated OER
3-D Beginning Graphs
Students explore the concept of big and small. They collect objects from the classroom, sort them by size, and create a graph using Duplo stacking blocks.
Curated OER
Can You Build It?
Students investigate the concept of perimeter. They design there own figure and measure the perimeter of it. The lesson is given the context of the shape being a path that is traveled by a ladybug. This provides the shape of the plane...

Shapes in Our World
Help your students explore shapes. They classify shapes and identify them in their everyday world. Plane shapes are explored, and they classify and identify the plane shapes.
Curated OER
A World of Symmetry
Students identify lines of symmetry. In this symmetry instructional activity, students create objects and identify their lines of symmetry. They answer questions about lines of symmetry. Students cut shapes out of cookie dough and...
Curated OER
Terrific Tangrams
Third graders construct tangrams. In this tangrams lesson, 3rd graders manipulate basic shapes to construct tangrams. Students explore how shapes can be combined in different ways and develop spatial sense.
Curated OER
Quandaries, Quagmires, and Quadrilaterals
Students classify, flip, slide, and turn a quantity of quadrilaterals.

Grade 5: Testing for Tessellations
Fifth graders use formal geometric language to describe polygons (and other shapes) that will tessellate the plane and those that will not. Students make generalizations about the characteristics of a polygon (or other shape) that will...
Curated OER
What Shape Am I?
First graders analyze characteristics of geometric shapes. They identify, describe, and create simple geometric figures. They analyze characteristics of geometric shapes and determine the defining attributes of a circle,...

Applied Science - Science and Math Lab
Students investigate topology. In this Applied Science lesson students explore higher, more abstract mathematics using tangles. Students make topologically related shapes.
Curated OER
Lines of Symmetry
Fifth graders explore the concept of symmetry using lines drawn through different shapes. The worksheet that is included in the lesson should be used to chart the lines of symmetry for the different shapes drawn.
Curated OER
Tessellation Trial and Error
In this interactive lesson, pupils review attributes of equilateral polygons. They are introduced to the concept of a tessellation. Using protractors and pre-cut shapes, students arrange a variety of tiles to create tessellations. They...
Curated OER
African Ceremonial Masks
Fourth graders examine and discuss the purposes and traditions of African ceremonial masks. They design and create African ceremonial masks using various materials.
Curated OER
Constructing Tangrams
Seventh graders visualize and identify geometric shapes after applying transformations on a coordinate plane. In this tangrams lesson, 7th graders construct a set of tangrams and then answer extension questions related to measurement,...
Curated OER
Compare 2-D Shapes
Second graders explore and analyze plane shapes. In this plane shapes lesson plan, 2nd graders evaluate shape attributes to classify shapes correctly. Students work in groups to create different shapes.
Curated OER
Terrific Tessellations
Students explore tessellations that are found in nature and everyday objects. They observe the works of M.C. Escher. Students create their own tessellations using pencil and paper.
Curated OER
Tessellations
Students identify shapes that will tessellate. They construct a tessellation using transformations. Students identify transformations in tessellations. They identify applications of transformations such as tiling and fabric design.
Curated OER
Tessellations Lesson
Fifth graders demonstrate their understanding of tessellations by watching a teacher prepared Powerpoint presentation and completing an activity. The students work independently to identify tessellations.
Curated OER
ARE YOU A TRIANGULATEER?
Young scholars explore about triangles and their relationship to the worlld around them. They are able to identify triangular shapes in their environment. Students are able to communicate to one another their understanding of triangles...
Curated OER
Interior/Exterior Polygon Angles and Tessellations
Students discover the sum of the interior and exterior angles of several polygons. In this Geometers sketchpad lesson, students work in groups to find the stated measurements of triangles, quadrilaterals, pentagons and hexagons. Students...
Curated OER
Tantalizing Tessellations - Lesson I
Students complete a chart (KWL) as a pre-assessment, study the history of tessellations (tilings), investigate the properties of tessellations, and make and evaluate photographs of "found tessellations" for a PowerPoint/HyperStudio...
