In this three-dimensional shapes geometry lesson, learners identify geometric solids and name their properties. They define "face," "edge," and "vertex," and construct geometric solids using marshmallows as vertices and toothpicks as edges.

How can we identify shapes in the Universe? High schoolers will compare and contrast elliptic and hyperbolic geometry. They will also explore one possible way to measure the curvature of the Universe, namely, by measuring the sum of the...

Second graders experiment with slides, flips and turns to understand motion geometry.  In this motion geometry lesson, 2nd graders navigate interactive motion geometry sites. Students  illustrate the results of motion using...

Students use geometric shapes to describe body parts. In this geometry lesson, students use geometry vocabulary as they discuss body parts. They practice drawing bodies using shapes based on a wooden model that is poised to show specific...

Here is a clever, cross-curricular lesson plan that combines art and geometry. Learners design a painting that uses geometrical shapes and is symmetrical. Sponge-shaped geometrical figures are used to design half a page and fold them to...

Group work and participation is used to perform a specified translation or reflection. In this geometrical translation instructional activity, small groups of pupils are each given a shape to plot on a coordinate grid. Each shape is then...

Students investigate the architecture in their hometown by visiting buildings.  In this geometry lesson plan, students examine buildings through photographs and explain the different geometric shapes found in the architecture....

Students explore points, lines and planes as it relates to geometry. In this geometry lesson, students analyze space and explain wy it is 3-D and not flat or 2-D. They solve problems involving volume and 3-D shapes.

Students investigate shapes and sizes by creating a riddle.  In this geometry lesson, students read one of two books and investigate facts about an object's size.  Students write a riddle using the facts they have read and cut...

Students make a quilt. In this geometry lesson, students discuss patchwork quilts and learn some different geometric shapes and patterns that are commonly used. Students explore designs with triangles and squares and then make their own...

Students explore radial symmetry.  For this 3 dimensional art and geometry lesson, students identify examples of radial symmetry in everyday objects. Students create an imprint using radial symmetry on clay tiles.

Students use geometry to create art. In this geometric graphing and patterns instructional activity, students create a helix-a-graph by plotting points on a grid that follow a certain pattern and analyze the drawing they created.

Make origami ducks with your class to reinforce geometry concepts and vocabulary; develop fine motor and visual translation skills; and enrich study of Japanese culture, the pond habitat, or migration. Create a whole group "worksheet"...

In this geometry lesson on cylinders, geometers explore how to find the smallest surface area for a given volume.  They use their knowledge to relate it to the real world by making a model of a livestock tank.

Middle and high schoolers participate in a seven-part lesson creating Escher-Esque tessellations. They demonstrate their knowledge of geometric transformations after viewing a PowerPoint presentation, conducting Internet research, and...

It's frog party time! With frog banners, frog juice, and a triangle hunt, your garden party is sure to be both entertaining and educational. The lesson connects geometry, earth science, and delicious snacks to teach kids about ecosystems...

Kindergartners identify geometric shapes by planting a fall garden. They start their seeds in containers that have different shapes, and keep track of their plants based on those shapes. This brilliantly designed and incredibly thorough...

Are you looking for a good 3-D geometry lesson that includes hands-on activities for your middle schoolers? Look no further than this one! Pupils use centimeter grid paper embedded in the plan, along with detailed construction...

Create the ultimate miniature golf course. The 93-page model curriculum unit from the Massachusetts Department of Elementary and Secondary Education contains nine lessons on understanding similarity in terms of both Euclidean geometry...

Youngsters explore visual arts by participating in a geometry identification activity. They read the book The Very Busy Spider and identify the techniques spiders use to create webs. Have you ever noticed that their webs are geometric...

Let's play ball! A great springtime activity to learn about ratios. This activity challenges learners to draw stadiums to scale on standard letter paper and also on construction paper. This three-day lesson plan includes a pre-assessment...

Leave no student behind with this differentiated geometry unit on perimeter and area. Over the course of five lessons, young mathematicians explore these foundational concepts through a series of self-selected hands-on activities and...

Study geometry through the concept of quilt design. High schoolers examine the geometric shapes in various quilts and then create their own quilts using geometric shapes that fit together. In the end, they write a paragraph to...

Grab your class and get them graphing polygons on a coordinate plane! They investigate the four quadrants, discover the x and y axis, and correctly plot ordered pairs. To show their comprehension, each child creates a coordinate picture...
