Take young mathematicians on an exploration of the world of 3-D geometry with this seven-lesson unit. After first defining the terms perimeter, area, and volume and how they apply to the real world, students continue on...

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.

Students explore geometric solids. In this geometry instructional activity, students listen to the book The Greedy Triangle by Marilyn Burns, then work in groups to sort geometric solids into various categories. Students define geometric...

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...

Learners construct triangles. In this geometry instructional activity, students create equilateral triangles. They also construct triangles where the sides are different. They use the lab to create and move shapes around with the Cabri...

Fifth graders participate in a review game of geometry topics. In this geometry lesson, 5th graders use the "Eggspert" interactive classroom game system to review the geometry skills taught that week. Students work in teams to complete...

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

Young scholars construct polygons. They identify attributes of three-dimensional shapes. Students name common three-dimensional shapes. They draw three-dimensional shapes, and sort three-dimensional shapes. Young scholars use K'NEX...

In this 2-D shapes lesson, kindergarteners review plane shapes attributes. They engage in a shape hunt in the classroom and create art using plane shapes. A good, hands-on lesson!

Aspiring astronauts construct a space vehicle using cylinders, cones, spheres, and rectangular prisms. This is an engaging method of learning about three-dimensional shapes. Note that the word cylinder is constantly misspelled in the...

Fifth graders explore shapes. They recognize and name two-dimensional and three-dimensional shapes. Pupils discuss the properties and criteria for each shape they find in real life and construct a Kid Pix project using pictures of the...

Students identify symmetry in road signs. In this geometry lesson, students explore objects in the real world for symmetry. They perform translation, rotation and reflection.

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.

Learners study parallel and perpendicular lines. In this parallel and perpendicular lesson, pupils explore 2-D shapes and determine if the sides are parallel or perpendicular.

Students investigate the creation of three dimensional drawings. In this geometry lesson, students analyze and complete orthographic drawings. They Cabri software to manipulate and move the drawings around.

Students investigate orthographic drawings. In this geometry lesson, students identify properties of three dimensional drawings in space. They solve problems using volume and area formulas.

Challenge the spatial thinking of your young mathematicians with this printable tangram puzzle. Using different sized triangles, squares, and parallelograms, children must figure out how to fit all the shapes together to create a square.

Students investigate polygons and construct ferris wheels. In this geometry instructional activity, students create a circle and differentiate properties of circles and polygons. They compare the relationship between angles and...

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...

Middle and high schoolers investigate all the different places in math that square root is present. In this geometry lesson, pupils discuss square roots as it relates to a right triangle and construction. They go over altitude, rise,...

Turn young mathematicians into landscape architects with this four-lesson series on area and perimeter. Beginning with a basic introduction to calculating perimeter and area using non-standard units of measurement, this...

Middle schoolers construct polygons by plotting points on a coordinate plane. Pupils connect the points and identify which polygons they have drawn. They will need graph paper to carry out the assigned activities. A vocabulary list,...

Students use specific dimensions to create a box. For this geometry lesson, students analyze the different properties of two and three dimensional shapes. They make conjectures and use it to solve problems.

Learners investigate architecture and construction by building a home from cardboard tubes.  In this housing instructional activity, students collaborate in groups to plan and create buildings they can fit in made from cardboard...
