Exploring Chords: Products of Chord Segments
Young scholars identify the properties of chords. In this geometry lesson, students multiply chord segments to find the solution to their problem. They construct two chords that cross on a circles.
Curated OER
Dream Bedroom Floor Plan
Students construct using Cabri software. In this geometry activity, students convert between units and apply the correct measurements to build objects. They create the room virtually and manipulate the shapes to the desired measurements.
Curated OER
Parabolas
In this parabolas activity, 10th graders solve and draw 10 different problems with figures related to various parabolas. First, they determine the vertex, focus, and the directrix in each equation. Then, students draw the parabola on a...
Curated OER
Area Of Sectors
Student find the area of a sector of a circle. In this geometry lesson, learners define the sector of a circle using a sketch. They find and identify examples of sector in the real world.
Curated OER
Geometric Shape Dances
Students use movement and dance in order to strengthen mathematical understanding of different geometric shapes. The movements are imitating the drawing of shapes and they pick one to make into a dance. Upon beginning the dance music can...
Curated OER
Approximating Pi
Young scholars approximate Pi using the lower and upper bound for the constant. In this algebra lesson, students work in groups of two to graph a circle and approximate Pi using the circumference. They repeat their estimation until they...
Curated OER
Are you in Golden Shape
Students solve and verify the solution for unknown measures. In this geometry lesson, students identify the properties of circles. They use the arc, angle and segment relationship to find the missing measures.
Curated OER
Shapes Around Us
Students create posters about geometric shapes in order to demonstrate their understanding of the different shapes. Students look for pictures in magazines to represent two-dimensional shapes, paste them on a poster, label the shape,...
Curated OER
Play Dough Day
Twelfth graders build a model of the following figures with the base from column I and the cross-section from column II. Draw the base with labeled axes on the graph paper and construct the figure on top of the base with the play dough...
Curated OER
Seven Sets of Area Problems
In this area instructional activity, students solve for the area of rectangles, parallelograms, triangles, trapezoids, kites, regular polygons, circles, and surface area. The worksheets is divided into seven different sets of...
Curated OER
Sketching Cones
High schoolers sketch cones and identify its properties. In this geometry activity, students calculate the surface area and volume of each three dimensional shape. they define and sketch prisms, pyramids and cylinders.
Curated OER
Ship Shape
Second graders explore shapes. After reading books about shapes, 2nd graders describe the properties of various shapes. They identify shapes if they have been rotated, flipped, or slid. Students create shapes using drawings and geoboards.
Curated OER
Skittles, Taste the Rainbow
Fifth graders learn and then demonstrate their knowledge of a bar and a circle graph using the classroom data. Students are given a pack of skittles candy. Students create a bar and circle graph indicating the results of the contents of...
Curated OER
It's a 3-D World Out There!
Students construct polygons. They identify attributes of three-dimensional shapes. Students name common three-dimensional shapes. They draw three-dimensional shapes, and sort three-dimensional shapes. Students use K'NEX materials sets to...
Curated OER
Topology and Geomery
Students relate topology to polygons. In this geometry lesson, students make the connection between different shapes and topologically equivalent relationships. They use Mobius strips to create and move shapes around.
Curated OER
Slides, Flips, and Turns
In this geometry worksheet, 2nd graders review how to determine which piece would complete the geometric shape that is pictured. They circle whether it was a flip or a slide to move the piece into position. They draw or write to explain...
Curated OER
Let's Explore the World of Triangles and Quadrilaterals!
Second graders explore the features of triangles and quadrilaterals. In this instructional activity on triangles and quadrilaterals, 2nd graders rotate with their group to five different activities all exploring a different aspect of...

Measurement
Fifth graders measure specified distances when given perpendicular lines. In this measurement lesson plan, 5th graders draw the lines themselves.
Curated OER
Measurement
Seventh graders measure surface area. In this geometry lesson, 7th graders find the surface area of various geometrical shapes. Using a computer program, students compute the area of 2-D and 3-D shapes. Students use...
Curated OER
Fractions, Decimals, and Percents
Students connect different mathematical concepts. They create a circle graph. Students then create a question in which they collect data in order to convert fractions to decimals and decimals to percents.
Curated OER
Polygons and Vertices
For this geometry worksheet, students analyze different polygons and relate it to a circuit board. They find the odd degree Euler circuit and identify the vertices of the odd degree. There are 3 questions with an answer key.
Curated OER
Symmetry
Students identify the different symmetry in polygons. In this geometry lesson, students identify line, rotational and point symmetry in different objects. They find the symmetry with 90% accuracy.
Curated OER
Match the Shapes
In this geometry worksheet, students match shapes that look alike or are the same. Students are given five sets of two shapes each where they are to draw a line from one shape to the corresponding shape that matches it.
