Curated OER
Polygons Defined
Fourth graders explore polygons. In this polygon instructional activity, 4th graders sort polygons according to their properties. Students discover the connection between polygons and the Greek language.
Curated OER
Intro to Geometry
Seventh graders identify a polygon and classify them using congruent sides and number of edges and vertices. Students transform two dimensional objects into three dimensional objects.
Curated OER
3-D Beginning Graphs
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.
Curated OER
Cones, Cylinders, Spheres
Students classify polygons by name and shape. In this geometry lesson, students identify the lateral surface of each conic. They differentiate between cones, cylinders and spheres.
Curated OER
Sketching Spheres
Students investigate spheres through sketches. In this geometry lesson, students sketch two and three dimensional shapes creating nets. They find and differentiate between the nets for prisms, pyramids, cones, cylinders and spheres.

Lewis Structures and Bonding
In this compounds worksheet, students complete a graphic organizer by filling in the chemical compounds structure, resonance, geometry, hybridization, and bond angles. Then students complete 2 short answer questions.
Curated OER
Technology Integrated Lesson
Students investigate symmetry in the real world. In this geometry instructional activity, students inter-relate math and technology. They create and name a variety of polygons.
Curated OER
Compass Designs
Students investigate the properties of two and three dimensional objects. In this geometry instructional activity, students differentiate polygons based on similarity and congruence. They make observation and interpret the data.

Design-A-Room Project (Part 3 of 3)
Students culminate a unit on measurement with a focus on area and perimeter. They design a floor plan of their dream room on graph paper showing the proper area and perimeter. They plan the budget for their room and make a 3-D scale...

Rectangular Gardens
Students create a rectangular garden using paper and tiles. In this geometry lesson plan, students investigate the largest possible rectangle that can be created given specific boundaries. They use grid paper to draw the rectangles...
Curated OER
Reflections
Students investigate image and pre-image. In this geometry lesson, students identify the reflection and rotation of different shape on a coordinate plane. They identify similarities and differences of image and pre-image of a reflection.
Curated OER
Geometric Word Problems
In this geometric figures worksheet, 10th graders solve and complete 11 different word problems. First, they find the area of a regular octagon with a given side. Then, students find the area of each shaded region. They also find the...

"The Greedy Triangle" by Marilyn Burns
Students discover which regular polygons can be used to tile a plane.
Curated OER
Regular Polygons
Fifth graders explore polygons. In this math lesson, 5th graders find examples of regular polygons in the classroom and measure the sides of figures to determine if they are regular polygons.
Curated OER
Polygon Jigsaw Puzzle
For this polygons worksheet, students put a polygon jigsaw puzzle back together to form the planet Earth. Students put 10 polygons together.
Curated OER
Pondering Polygons
Seventh graders use block letter writing to help classify polygons. They use their own names which helps to keep them engaged during the lesson. Finally, 7th graders play a classification game naming different polygons.
Curated OER
Pauli's Magical Water
Students predict the shape of molecules using VSEPR theory. In this chemistry lesson plan, students differentiate a polar and nonpolar molecule. They discuss why water's polarity is very important.
Curated OER
Prime and Composite Numbers
Sixth graders inspect prime and composite numbers. Using graph paper, they draw as many different shaped rectangles as possible. They use the dimensions of the rectangles to discuss prime and composite numbers. Students create a chart...
Curated OER
Angles and Parallel Lines
Sixth graders draw parallel and intersecting lines to observe and examine the characteristics of alternate interior angles, vertical angles, corresponding angles, and supplementary angles. Through observation, they discover the...
Curated OER
Lines, Rays, Line Segments, and Planes
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
Curated OER
What are the Kinds of Triangles?
Fifth graders classify triangles. In this triangle lesson, 5th graders learn about the characteristics that make up a triangle. They are instructed through video, PowerPoint slides, and teacher-led demonstrations.
