Why are only four colors needed to color webs from regular pentagons, not five? An assessment task requires young mathematicians to first construct regular pentagons using a compass and straightedge, then has them consider a shape...

Explore lines tangent to a circle. In this math lesson, students manipulate circles and lines on a TI calculator. They draw a circle  and analyze perpendicular lines intersecting the circle in only one place. This activity works...

Math scholars study conics and how they are used today. For this mathematical lesson, pupils construct and slice cones after viewing a demonstration. 

Fourth graders discuss and examine examples of the different types of angles. After learning the names of the geometric shapes students identify the types of angles and then complete the Kidspiration activity, Identifying Angles.

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 are given magazines, scissors, glue, and one sheet of construction paper. They look for pictures showing real life representations of rectangular prisms, spheres, cones, and pyramids. Pupils cut out pictures showing each of...

Second graders identify the attributes of various shapes and estimate the weight of the objects. In this geometry lesson, 2nd graders identify the attributes of concrete objects and use a pan balance to weight them.

Third graders utilize different types of computer programs, such as Microsoft paint and Microsoft Word to study and create different types of polygons. They use PowerPoint to create a story about a shape and others that it meets during a...

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

Third graders investigate shapes in our world. In this geometry instructional activity, 3rd graders describe plane and solid shapes and identify angles, solid objects and lines of symmetry. Students use online resources, graphic...

Children who are blind need to constantly be engaged in building conceptual understandings of the world around them. This activity will help them grasp the concept of shape, identify shapes, and consider shapes as they are used to...

Young geometers investigate two-dimensional figures using coordinate grids. They identify polygons and draw examples of their reflection, rotation, and translation on a coordinate grid. And they complete a worksheet practicing examples...

Junior designers brainstorm the elements that a bedroom might have, such as a bed, television, and dresser. They identify which items are needs and which are desires. They practice measurement skills in the classroom by determining its...

Here's a task that is out of this world! Given a description of a fictional cube-shaped planet, scholars answer a set of questions about the planet. They create a two-dimensional map and consider the distances between locations on the map.

Third graders engage in a instructional activity that focuses on the attributes and forming of a cube. They construct a cube using different combinations while comparing a square with only two-dimensions. Students fold paper while...

In this algebra worksheet, students solve word problems using linear equations and algebraic symbols. There is one problem with an answer key.

Primary geometers create a picture using tangrams. In this geometry lesson plan, students read Grandfather Tang: A Tale Told with Tangrams, cut out their own tangrams, and choose a character from the story to make using their tangram...

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...

Take young scholars on a trip through history with this unit on the mathematics and architecture of the Mayan civilization. Starting with a introduction to their base twenty number system and the symbols they used, this eight-lesson unit...

Students explore optical illusions. In this Applied Science lesson, students view optical illusions and record the data of what they see. Students graph the data that they collect.

In 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...

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...

Students build three-dimensional rough draft for a story by creating objects, people, places, animals, etc., with clay, and write story in a journal, poem, or other written form.

Students complete a two-week unit involving design and construction concepts. They watch a PowerPoint presentation about geometric shapes, draw the fourteen shapes incorporated in bridge construction, and in small groups design, build,...
