Congruence with Robot Gobot
Learners identify the properties of solids and polygons. In this geometry lesson, students identify the different measurements of a triangle. They use congruence parts and theorem to prove their answer.
Curated OER
Transformations-Shapes on the Move
Students examine transformations. In this math lesson, students view and describe flips, slides, and turns. Students practice making transformations with shapes.
Curated OER
Fractals and the Chaos Game
Students explore the concept of fractals. In this fractals lesson, students play the "Chaos Game" via an applet. Students place dots on the screen to recognize that they have created Sierpinski's Triangle.
Curated OER
Constructions, Sketches, and Drawings
Students explore the concept of constructions, sketches, and drawings. In this constructions, sketches, and drawings lesson, students discuss the differences between constructions, sketches, and drawings through teacher led discussion.

Teaching the Bell Tetrahedral Kite
Learners complete readings on kite making and kite flying. They analyze how the parts of a system interconnect and influence each other. Students identifies and uses color and form in a 3D artwork.
Curated OER
Exploring Volume of Cylinders
Tenth graders investigate the volume of a cylinder. In this geometry lesson, 10th graders create three-dimensional cylinders and use a ruler to determine the dimensions. The lesson progresses to the use of the formula to find...

Geometry Journal: Classifying Solids
In this geometry worksheet, 10th graders respond to journal prompts related to prisms and classifying solid shapes. The two page worksheet contains nine questions. Answers are included.
Curated OER
Concurrent Lines in Triangles
Students explore the concept of concurrent lines in triangles. In this concurrent lines in triangles lesson, students work in groups to investigate properties of concurrent lines in acute, right, and obtuse triangles. Students use a...
Curated OER
Lines, Segments, and Rays
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.
Curated OER
Opening A Cube
Fifth graders investigate mathematical concepts related to the construction of a three dimensional cube. They construct the cube from two dimensional patterns and compute the surface area. Students also define the faces, edges, and...
Curated OER
Transformation Trio
Students identify the transformation and rotation of polygons. In this geometry lesson, students use picture to perform rotation, reflection and transformation. They identify the coordinate points of the new transformation.
Curated OER
Review Geometry Week
Fifth graders participate in a review game of geometry topics. In this geometry lesson plan, 5th graders use the "Eggspert" interactive classroom game system to review the geometry skills taught that week. Students work in teams to...
Curated OER
Using Concept Maps to Design 3D Spheres
Young scholars create three dimensional shapes using concept maps. In this geometry lesson, students investigate the impact of mental schemas on humans. They collect data on this topic and plot their data on a coordinate plane.
Curated OER
Venn Diagram and Shape Sorting Lesson Plan
Students use Venn diagrams to represent classifications of shapes and to use counting arguments to find the number of objects in a given set.
Curated OER
Terrific Tessellations
Students explore tessellations that are found in nature and everyday objects. They observe the works of M.C. Escher. Students create their own tessellations using pencil and paper.
Curated OER
Introducing Angles
Sixth graders identify, compare and interpret the characteristics of polygons and angles in order to meet spatial sense, geometry and measurement standards. They also sort shapes into three categories, polygons (regular and irregular)...
Curated OER
Determine the Coordinate of Transformations
Students investigate transformation on a coordinate plane. In this geometry lesson, students identify pairs of coordinates and their location on the grid. They perform rotation and reflection of each polygon.
Curated OER
Patterns In Fractals
Middle schoolers find number patterns in the generation of several different types of fractals.
Curated OER
Listen to a Shape
First graders identify basic shapes (circle, square, rectangle, triangle) and describes the attributes of each. They use magazines to find examples of each shape, and then make a collage.
Curated OER
Shape Makes a Difference!
Students learn the difference between perimeter and area by watching a video and a hands on activity.
Curated OER
Venn Diagram Lesson Plan
Students use Venn diagrams in order to classify different objects and numbers. They then use "Venn Diagram Shape sorter" applets on the computer.
