Young scholars discuss tangram vocabulary, and act out slide, flip, and turn. They observe tangram puzzles on a web page, and solve their own tangram puzzles.

Sixth grade students: design a stained glass window, submitting their initial plan detailing the measurements of all lines and angles. Seventh grade students: create a scale drawing of their own geometric family of four members.

Students review geometry unit content through a vocabulary/word game. They demonstrate understanding using geoboards to answer questions. They work in groups and it's a race to the correct answer.

Students view a right triangle displayed by the teacher. Students measure legs and the interior angles of the triangle. They look for a pattern or relationship between the legs and angles. Students use pegboards and string to create more...

Students make and fly a sled kite out of plastic garbage bags, dowel rods, and more. In this kite lesson plan, students plan the kite to have symmetry and make adjustments as they test it.

Second graders are introduced to geometry by a teacher made puppet called Geo George.

Seventh graders solve word problems involving real world situation. In this geometry lesson, 7th graders solve problems related to volume. They apply the formulas taught in geometry.

Young scholars identify the secant segment of a circle. For this geometry lesson, students investigate secant lines formed outside the circle. They use Cabri software to create drawings and explore circles and secants.

Students creating chords intersection using circles. In this geometry lesson, students create visuals of chords ad their properties using Cabri technology. They measure the chords and explore the relationship among chords.

Students listen to a read aloud of The Quiltmaker's Gift by Jeff Brumbeau finding examples of symmetry in the illustrations in the book.

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.

Student sinvestigate the area and perimeter of polygons. They differentiate between similar and congruent polygons.. They identify the ratio and proportions of the sides and angles of polygons.

Fourth graders examine the properties of geometric solids. Given geometric figures, they brainstorm observations. In groups, 4th graders identify solids and discuss the physical properties. Each student creates a Venn diagram and...

Fifth graders participate in a review game of geometry topics. In this geometry lesson, 5th graders use the "Eggspert" interactive classroom game system to review the geometry skills taught that week. Students work in teams to complete...

Fifth graders demonstrate their understanding of tessellations by watching a teacher prepared Powerpoint presentation and completing an activity. The students work independently to identify tessellations.

Seventh graders complete activities to further their understanding of area formulas. In this area lesson, 7th graders watch as the teacher uses Polystrips to model parallelograms. Students find the area of a rectangle and answer...

Students calculate the measurement of a central angle. In this geometry lesson, students identify properties of circles. They use Cabri software to create and analyze graphs.

Students define keywords that are important to solve problems. In this geometry lesson, students find the arc length and angle of a circle. They convert between radians and degrees.

In this spatial relations worksheet, students identify the number of triangles in a given figure, identify the number of cubes that a plane intersects, and determine the number of line segments in a given cube. This three-page worksheet...

In this 3D figure learning exercise, students observe the net of a 3D figure where you open up the figure and tell if it is an accurate representation of that figure. Students complete this for 3 figures.

Students investigate the properties of circles. In this geometry lesson plan, students calculate the area and perimeter of a triangle. They identify the perimeter and radius length of a circle.

Students calculate the measurements of the inscribed angles of a triangle. In this geometry lesson, students relate the hypotenuse of a right triangle and the diameter of a circle to each other. They calculate the diameter of a circle as...

Pupils calculate the distance from the vertex of a triangle to the center. In this geometry lesson, students find the shortest distance between a point and the vertex of a triangle. They relate this concept of distance to the real world.

Students identify different polygons. In this geometry instructional activity, students name polygons using the number of sides. They calculate distance and slopes using the correct formula.
