Curated OER
Grasping Geometry
Students investigate geometric shapes in their environment, make a geometric design, and write paragraphs describing the design.
Curated OER
Geometry House!
Fourth graders use computer drawing tools to create a house of geometric shapes.
Curated OER
Patchwork Math
Students recognize and identify shapes in their environment. They investigate why objects can be composed of several different shapes. They follow a pattern to recreate designs using various shapes.
Curated OER
Finding Remainders in Pascal's Triangle
Students use clock arithmetic to find remainders. In this patterns in math instructional activity, students explore the relationship between clock arithmetic and remainders using a computer applet. Students also identify patterns in...

"Sweet Clara and the Freedom Quilt" by Deborah Hopkinson
Students create paper quilts of their own using the isometric grid that tessellates the plane or the fraction quilt square.
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.

What’s Your Coordinate?
Your middle schoolers will show what they know with their bodies when they become the coordinate plane in this conceptual development unit. Starting with the characteristics of the coordinate plane, learners develop their skills by...
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...
Curated OER
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 lesson, 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
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
Terrific Tangrams
Third graders construct tangrams. In this tangrams instructional activity, 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.
Curated OER
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
Tessellating Ceiling Tiles
Students transform polygons. In this tessellating lesson, students design a picture containing a translation and a rotation. They create a template of a translation or a rotation. Students tessellate and decorate a...
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,...
Curated OER
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
Game Day
In this finding combinations activity, students find as many different combinations for the games possible. Students list the different combinations and explain how they know they found all of them.
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
Geometric Solids
Students identify and create simple geometric shapes and describe simple spatial relationships. Through discussion, hands-on activities and show and tell, they identify geometric solids in real life and create graphs of commonly found...
Curated OER
Tessellation Trial and Error
In this interactive lesson, students 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
It Counts
Students assign numbers to describe objects. In this number lesson, students assign numbers to objects and compare more, less, and equal values. They write down descriptions of plants including the number of leaves and height of the...
Curated OER
Constructing Tangrams
Seventh graders visualize and identify geometric shapes after applying transformations on a coordinate plane. In this tangrams instructional activity, 7th graders construct a set of tangrams and then answer extension questions related to...
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.
