Students explore models of three-dimensional shapes. In this geometric shapes lesson, students use hands-on manipulatives to explore three-dimensional shapes. Students predict whether each shape will roll or slide.

Students construct two dimensional models to illustrate squared numbers. For this geometry lesson, students use graph paper and an x/y axis to build squares exponentially. Students identify powers and relationships between various...

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...

Students explore geometric shapes.  In this kindergarten geometry lesson, students create a fall quilt consisting of three different paper geometric quilt squares that when assembled form a scarecrow, a pumpkin, and a crow. ...

Eighth graders classify geometric figures.  In this polygon lesson, 8th graders identify given geometric figures.  They compare and contrast different polygons.  Students name line segments, identify parallel lines, and...

In this math instructional activity, students investigate reflections of geometric shapes by completing 15 problems. Students analyze a picture of a geometric figure drawn on a dot grid and draw the reflection.

Tenth graders predict the shape of a geometric figure in 3D. In this geometry lesson, 10th graders construct 3D shapes to perfect their knowledge of measuring and predicting. This assignment is also available as an online interactive...

Fifth graders use formulas for calculating areas of squares and rectangles to find area of complex figure, compare their own ideas with their classmates' ideas, and recognize that there are multiple methods for finding area of complex...

For this math worksheet, students investigate tessellations. Students analyze geometric figures and indicate if the shapes tessellate. Students draw and color their own tessellating pattern.

In this math worksheet, students read information about 6 types of polygons and their sides and angles. Students then answer 5 questions about the geometric figures.

In this squares worksheet, students analyze a group of geometric figures and look for squares. Students color all the squares they see.

In this shape and figure descriptions activity, students name the shape described and draw it. Students complete this for 2 shapes.

Three solid figures are lined up down the left side of the page to be compared to three nets down the right side. Learners simply decide if the corresponding net matches the solid figure. Be aware that the publisher's watermark is...

Congruent figures: two figures that want to be just like each other. Individuals learn to distinguish between figures that are congruent and those that are not. Measuring the lengths of line segments and angles helps in this endeavor.

This hands-on lesson takes young geometers on a tour of 2D polygons and 3D polyhedrons. After exploring different web resources and discussing geometric shapes, small groups construct models of polyhedrons using bendable straws. Note:...

Develop a more precise definition of similar. The lesson begins with an informal definition of similar figures and develops the need to be more precise. The class learns about dilations and uses that knowledge to arrive at a...

Proofs are usually an intimidating assignment. An engaging lesson focused on geometric proofs may reduce the anxiety! Pupils choose between several triangle proofs to complete and work on completing them. The...

High schoolers use diagrams of the constellation Orion and the constellation Ursa Major which show the distances between the stars of the constellations. They calculate the perimeters of each, find the average distance of the stars for...

Students explore what happens when geometric figures are transformed on the coordinate plane. They work in pairs, moving geometric shapes in the plane, and formalize their rules as functions.

A basic set-up leads to a surprisingly complex analysis in this variation on the question of surrounding a central circle with a ring of touching circles. Useful for putting trigonometric functions in a physical context, as well as...

Young mathematicians connect vectors to geometric shapes by watching a video that expresses vectors in relation to the sides of geometric figures. They then apply what they learned by completing a worksheet of practice questions.

Cover the field. Pairs investigate two different rolls of astroturf to cover a football field. The learners determine which type of roll is the most cost effective. Scholars write letters to the athletic director explaining their...

Take some time to reflect on graphing. Learners count a point's distance from the line of reflection to create reflections of geometric figures. Given the rules for four basic lines of reflections, pupils determine the points to create...

In this sea squares worksheet, 10th graders solve 5 different problems that include various geometrical figures. First, they draw a number line using one color. Then, students draw 2 obtuse angles and 3 isosceles triangles with different...
