Students examine two- and three-dimensional shapes and figures. Individually, they practice identifying the shape from various viewpoints. By completing this activity, they develop a spatial sense about how figures and shapes are...

Third graders use pattern blocks of one shape at a time to try to create a similar shape. They compare the perimeter of the new figure with the perimeter of the original shape and look for a pattern. Students use the pattern to predict...

Learners analyze characteristics and properties of two- and three-dimensional geometric shapes and develop mathematical arguments about geometric relationship

First graders explore shapes. In this geometry instructional activity, 1st graders make shapes with geo-boards, use play-dough to make three-dimensional figures, and make a shape book using pre-cut shapes.

Emergine space engineers discover the area of complex geometric shapes. They find that, just as a spacecraft is composed of many smaller parts, so can polygons be broken into smaller shapes.

Students scan the classroom to find different common shapes. They listen as the teacher defines polygon and regular polygon. The teacher demonstrates regular polygons via the Internet and the "Math is Fun" web site. Students go outside...

Second graders utilize manipulatives (pentominoes) to demonstrate knowledge of: lines of symmetry, slides, reflections (flips), rotations (turns), area, and perimeter. This lesson gives students a meaningful way to practice these...

Students investigate proofs used to solve geometric problems. In this geometry lesson, students read about the history behind early geometry and learn how to write proofs correctly using two columns. The define terminology valuable to...

Students explore the volume and surface area of three dimensional figures. Through the use of video, students discover three dimensional shapes, their uses in real-life applications, and methods used to calculate their volume and surface...

In this math and science worksheet, students read about the process of photosynthesis and plant growth. They determine how a plant's ability to create food is dependent on the surface area of its leaves using geometric calculations. They...

Students determine that two figures are similar or congruent by investigating figures that are similar and figures that are congruent. They prove that two figures are similar or congruent by using definitions, postulates, and theorems.

Students use an online dictionaries to define key geometric terms. They explore several websites to help them differentiate the terms reflections, translations and rotations as they apply to geometry and then complete an assessment...

For this perimeter and area worksheet, 9th graders solve 17 various types of problems, mostly word problems related to determining the area or perimeter of a geometric shape. They also determine the area and perimeter of shaded portions...

Students access a variety of Egyptian Culture and pyramid related resources on the Internet. They explore various websites, read articles, create an Egyptian art figure, construct a model of a pyramid, and describe the mummification...

Sixth graders complete several activities that involve coordinates and graph paper. They visualize and identify geometric shapes after applying transformations on a coordinate plane. Finally, 6th graders draw and label a coordinate...

In this volume activity, learners calculate the volume by finding out how many units each figure has. Students complete 4 problems where they find the volume.

Pupils explore the relationships among the lengths, areas, and volumes of similar solids. They also discover what effect doubling the dimensions of a figure has on the resulting area.

Eighth graders engage in a lesson that is concerned with examining two dimensional figures with different properties that include circles, triangles, queadrilaterals, etc... They identify the types of figures that is identified as polygons.

Fifth graders use estimation to solve word problems. In this fractions lesson plan, 5th graders decide whether or not an answer to a work problem is reasonable by applying their knowledge of fractions, decimals and estimation. This...

Sixth graders explore three-dimensional objects. Using various objects found in the classroom, they identify faces, edges, and vertices of objects. Students create their own objects. They describe the polydron, telling the faces,...

In this geometry worksheet, students find the measures of the side of a triangle. They use the Pythagorean Theorem to find the different parts of a right triangle. There are 10 questions with an answer key.

Students choose a polygon to define and describe, and use Power Point and the Internet to present their polygon.

In this geometry worksheet, students draw a line from each of four shape on the left to the matching shape on the right. They match colors and shapes which include a diamond, a circle, a triangle and a square.

In this 3D shape instructional activity, students review the names of 4 shapes on page one and color each shape a specific color to match the key on page two.
