Students are introduced to lines, rays, line segments and planes and study the differences between them. They also practice graphing lines, rays, line segments and planes

Students discuss reasons to record the location of stars. They view a picture of the night sky, and discuss constellations. Students complete a worksheet of the various shapes they see in the constellations.

Pupils explore geometry by participating in a shape identification activity. In this figure dimensions lesson, students identify the difference between 2 and 3 dimensional shapes by their vertices and faces. Pupils examine blocks in...

Students study geometric images and polyhedrons. In this geometry lesson, students complete several activities to learn about geometric shapes and classify polyhedrons from polygons. Students watch a video, complete a web-directed...

Ninth graders access a star worksheet and determine properties of polygons.  In this investigative activity students complete a worksheet and discuss myths. 

Students identify polygons and calculate perimeter. In this geometric shapes lesson, students complete a worksheet identifying various polygons and calculating the perimeter of triangles and quadrilaterals.

In this geometry learning exercise, 3rd graders draw line segments into the shape and divide it into other shapes given. Then they divide the pentagon and hexagon in different shape parts using line segments. Students also write down...

Set your pupils up to start on geometry by teaching them some introductory terminology. Pupils learn the terms by reading a short passage and looking at examples. They then respond to five questions related to the text.

Make sure your learners are well-versed in circles with a reading passage. Pupils will pick up some important circle-related terms as they read and respond to the five included questions.

Scholars can use area formulas, but can they apply what they know about area? The lesson challenges learners to think logically while practicing finding area of shapes such as rectangles, circles, parallelograms, triangles, and other...

Can you build it? Yes you can! This interactive game includes four design challenges presented on separate cards. The cards outline the challenges with limited restrictions but with an end goal in mind. The competitions include building...

Explore the mathematics of the paper snowflake! During the five lessons progressing in complexity from K through 12, pupils use spatial geometry to make predictions. Scholars consider a folded piece of paper with shapes cut out....

Help learners understand that perimeter and circumference are one in the same. Learners apply their skills to determine the perimeter/circumference of triangles, rectangles, and circles. They then use the same strategy to find the...

Geometry is all around us—if we're only willing to look. The final three activities of the Fun with Solids unit continue work on surface area and volume. For lesson three, scholars investigate the formulas for spheres and solve a problem...

Fifth graders create polygons requested by their teacher. In this polygons lesson, 5th graders watch a video and listen to a song about polygons. Then, students take turns labeling various polygons and practice making polygons.

In this shape recognition worksheet, students study the various 3 dimensional figures and identify each one. Students label the 10 figures.

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

Fifth graders use their arm, toothpicks, and marshmallows to create lines, segments, and rays. In this lines, segments, and rays lesson plan, 5th graders learn how these appear on a plane.

Students examine tessellations and their geometric properties. Students also develop a better understanding of lines, planes, angles, and polygons.

Fourth graders examine mirror symmetry. In this symmetry lesson, 4th graders discover that symmetry is not always vertical or horizontal. Students cut and fold shapes along lines of symmetry.

Students create Post-It note fundamental regions to tesselate. They make tesselations using computer software or websites. They create a jacket design with tesselation and determine the cost of production.

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.

In this reflections worksheet, students reflect three sided and four sided shapes across a graph. Students complete 6 reflection problems.

Fifth graders use formal geometric language to describe polygons (and other shapes) that will tessellate the plane and those that will not. Students make generalizations about the characteristics of a polygon (or other shape) that will...
