Learners identify different types of polygons. In this geometry instructional activity, students differentiate between convex and regular shapes. they identify the names of two and three-dimensional objects.

Seventh graders solve word problems involving real world situation. In this geometry lesson, 7th graders solve problems related to volume. They apply the formulas taught in geometry.

Third graders discover geometric shapes by completing a series of games and activities. Using ropes with knots tied every foot, they make shapes such as squares, triangles, and hexagons. In pairs, 3rd graders use pattern blocks to...

Students investigate the affect shape has on the ability of a solar panel to collect sunlight.  In this collecting sunlight using a solar panel lesson, students determine which solar panel shape collects the most sunlight. ...

Sixth graders investigate the area of polygons. In this geometry lesson, 6th graders calculate area of prisms using geometric formulas. They work with prisms and other rectangular shapes.

Students identify and create simple geometric shapes and describe simple spatial relationships. Through discussion, hands-on activities and show and tell, they identify geometric solids in real life and create graphs of commonly found...

Second graders explore the features of triangles and quadrilaterals. In this lesson on triangles and quadrilaterals, 2nd graders rotate with their group to five different activities all exploring a different aspect of geometry.

Students calculate the surface area of different polygons. In this geometry lesson, students practice calculating the volume of spheres. They work with cones, cylinders and rectangular prisms.

Explore the concept of building equations for perimeter and circumference. Learners use rulers to measure the perimeter of half a sheet of paper.  Then fold the sheet of paper numerous times, each time measuring perimeter. ...

In this area worksheet, students calculate area of shapes using shaded grids, writing answers in cube units. A reference web site is given for additional activities.

Students classify prisms according to their attributes. In this classifying prisms lesson, students explore different prisms. Students generate observations of the attributes and classify the prism correctly.

Second graders identify and describe basic geometric solids. Working as a class, 2nd graders describe geometric solids using the proper vocabulary and counting faces, bases, corners, and edges. In pairs, students use a computer drawing...

Fifth graders work with polygons.

Students work with three dimensional objects. In this geometry lesson, students examine models of spheres, cones, cubes, prisms, and pyramids, and identify them by their edges, vertices, and faces.

Students study geometric shapes, lines, and the primary colors as they create Mondrian-like art prints.

The objective of this activity is to find the percent of the area of a two squares overlapping. Mathematicians find the ratio of area for the part that overlaps to the rectangle formed. The final answer is a percent as a rate per 100....

In this volume worksheet, students solve 12 short answer and multiple choice problems. Students find the dimensions of prisms given their volume in terms of quadratic and a linear expression.

In this 2D figure worksheet, learners pick which figure they are given. Students choose from 4 figures in each of the 4 problems they are asked.

In this volume of a prism worksheet, students calculate the volumes and missing lengths of seven prisms.  The solutions are provided.

Even middle schoolers still enjoy experimenting with bubbles! They execute a series of experiments enabling them to distinguish between convex and concave surfaces, explore the properties of buoyancy, surface tension, and density,...

With the help of the Area Officers and Perimeter Patrol, you learners will develop a better understanding of area and its relationship to perimeter. First, they view a video clip from Cyberchase, and then they visit a website to...

Partners use materials to wrap three-dimensional objects to determine the formula for surface area. The groups use an orange to calculate the amount of peel it takes to completely cover the fruit. Using manipulatives, individuals then...

Middle-schoolers still enjoy playing with bubbles! In this series of eight laboratory activities, science learners explore convex and concave surfaces, angles, gas laws, buoyancy, density and more! 

To take the longest path, go around—or was that go over? Class members measure scale drawings of a cylindrical vase to find the height and diameter. They calculate the actual height and circumference and determine which is larger.
