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...

Play a coordinates game to encourage collaborative learning and grid use! Learners plot points on grids and play a game that challenges them to locate a specific point on a coordinate grid by using horizontal and vertical movements.

Upper elementary and middle schoolers explore the properties of various polygons. They use video, resource links, and engage in hands-on activities in order to construct geometric nets. This fine plan should lead to increased...

Here is a way to help your charges identify circles and spheres. In this shapes geometry and technology lesson, students identify and draw circles and explain the related attributes. They recognize circles and spheres while exploring...

Compare two- and three-dimensional shapes and construct three dimensional models from two-dimensional shapes. Diagram the shapes and reflect about the process in writing.

Build on your learners' previous knowledge of geometric shapes and symmetrical figures. Then set them out to take photos of geometric shapes on campus. They assess whether the photos contain symmetry or not. 

Seventh graders practice finding the area and perimeter of polygons. In this polygon area lesson, 7th graders brainstorm shapes and take a walk to locate shapes. Students record properties of shapes and use various shapes to make a...

Students explore intersecting lines. In this intersecting lines instructional activity, students investigate shapes consisting of parallel, perpendicular, and similar lines. Students investigate these lines in shapes around them.

Create and investigate nets for solid shapes with your class. They identify the different parts and faces of each polygon and solid then calculate the surface area and volume of cones. They use circle sectors of varying sizes to build...

Identify the nets for prisms and other geometric shapes. Learners calculate the surface area of the rectangular prism then sketch the shapes of prisms and other polygons. Unfolded cereal boxes are used as a visual aid, great idea!

Do this as a whole-class activity by projecting this simple counting learning exercise. Learners count a set of 14 leaves, recording the total number.  Then, they examine four sets of bees and indicate which one shows 11. This can...

Learners use manipulatives to study shapes. They sort shapes and use correct geometric terminology to describe them. Learners find real-life examples of 2 and 3 dimensional shapes, and classify figures in their classroom according to...

First graders identify various shapes in everyday objects. in pairs, 1st graders go on a shape field trip to locate various objects of different shapes. They photograph the objects and later use the prints to write sentences describing...

In this polygons and angle measurement worksheet, learners identify polygons and determine the measurement of each angle of the polygon. They identify parallelograms and justify why objects are or are not polygons. This four-page...

Students investigate basic geometric concepts. In this geometry lesson, students explore solids through measuring and modeling. This assignment models the importance of understanding concrete objects in geometry.      

Students explore the concept of big and small. They collect objects from the classroom, sort them by size, and create a graph using Duplo stacking blocks.

Students are introduced to the concept of Objects in Programming and identifying the parts of an object. They view the radio objects movie and then brainstorm household objects that can be represented as a series of controls and displays.

Students compare and describe objects of differing lengths that are presented in a Mathkeys software compare mat. Working in pairs, one student is the chooser who sets up the objects while the other student is the sizer who puts the...

In this math terms worksheet, middle schoolers answer 4 multiple choice questions about the meaning of congruent, extrapolation, exponents, and integers.

Learners calculate volume using the correct formula and the correct unit. They explore different prisms, spheres, cubes, and cones as they calculate volume and relate it to depths in oceans.

In this math learning exercise, students label events as independent or dependent. They find the probability of a series of events happening.

Third graders explore vocabulary associated with three dimensional figures.  In this transformations instructional activity, 3rd graders create two dimensional nets for three dimensional figures.  Students become familiar with...

Students compute area.  In this perimeter, area and volume lesson, students examine given objects and determine the perimeter, area, and volume of each. 

Students identify lines of symmetry.  In this symmetry lesson, students create objects and identify their lines of symmetry.  They answer questions about lines of symmetry.  Students cut shapes out of cookie dough and...
