Middle schoolers construct a three-dimensional model of a city using both similar and congruent figures and geometric transformations. City must have at least ten buildings with each building labeled and may be constructed out of paper...

Geometry students will be ecstatic about these engaging and enlightening end-of-the-year projects! Types of project ideas include interviewing a geometer, an ABCs of geometry poster, an engineering lab report, and origami work. 

For 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...

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...

Apply geometric properties and formulae for surface area and volume by constructing a three-dimensional model of a city. Learners use similar and congruent figures and transformations to create a city of at least 10 buildings. They trade...

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

Fifth graders examine the geometry of quilts. They discuss the history of quilting, design two nine-patch squares, exchange one design on an Internet bulletin board, and construct a hot pad that is quilted.

Students create a quilt square for a class quilt using at least three, two-dimensional geometric figures. They research and write a brief description of at least two different quilt patterns that they find. Pupils discuss that quilts are...

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 includes a pre-assessment...

Eighth graders complete a unit of lessons on basic geometry concepts. They participate in a variety of activities, culminating in a project that involves publishing a booklet or a poster that presents the major geometry concepts from the...

Students make a quilt. For 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 participate in a instructional activity that covers the concepts of solving equations and inequalities. To master the concept they must demonstrate visually and verbally how both sides of an equation must be balanced. They...

Define and identify the three basic forms of symmetry translation, rotation, and glides with your class. They cut out and arrange paper pattern blocks to illustrate symmetry, create a Cartesian graph, and design a rug with a symmetrical...

Ever dream of becoming an architect? Here's your chance to give it a try. After reviewing facts about triangles and quadrilaterals, pupils learn about the basics of architecture by talking to an architect or housing expert. They use...

This engineering activity gets youngsters working together to design and construct a bridge. Each bridge is tested in front of the class to discover how much weight it can hold before showing any change in form. The lesson plan does not...

Students investigate ways to enhance an object's flying ability.  In this model construction lesson, students construct two paper airplanes, one of which is twice as big as the first.  Students compare and contrast the two...

Geometric shapes are used in math and in art. Learners discuss the various names, dimensions, and attributes of geometric shapes, then apply that knowledge to design a vase. They use 3-D shapes to make a cubist-style vase out of clay.

Students construct an origami models of different molecules. In this chemistry lesson, students explain what expansive soils are made up of. They discuss what happens when this expansive soil expands or shrinks.

Students create a new playground design to present to elementary students during Playground safety week. They review basic geometry to use in observing and recording the equipment on a local playground. They research playground safety...

Students read the book The Math Curse by Jon Scieszka and study geometry. In this geometry lesson, students identify geometric shapes and their properties. Students create a geo-critter.

Students complete geometrical shapes construction activities. In this geometrical concepts lesson, students cut shapes from a worksheet to create a geometrical study activity. Students analyze their shapes and complete a table. Students...

Students identify geometric patterns in quilts. For this geometry lesson, students view various types of quilts and identify the geometric shapes. Students construct one hundred patch paper quilts using geometric shapes.

Students explore symmetry. For this geometry lesson, student identify and define bilateral symmetry, radial symmetry, pentagonal symmetry, hexagonal symmetry, and cubic symmetry. Students construct examples of these types of symmetry and...

Students create various geometric shapes with their younger grade "buddy partners." They identify and discuss various geometric shapes, and using gumdrops or marshmallows and toothpicks, construct different flat and three-dimensional...
