Exploring Properties of Rectangular Prisms
Students explore the properties of rectangular prisms. In this geometry lesson, students identify properties of two and three dimensional shapes. They use Cabri technology to create polygons and solve problems.
Curated OER
Pythagorean Theorem
Students investigate the Pythagorean Theorem. In this seventh through twelfth grade geometery lesson, students explore the Pythagorean Theorem and its converse and use it to find the length of the missing side of a right triangle.
Curated OER
Polygon Sum Conjecture
Students calculate the sum of the angles of a polygon. For this geometry lesson, students use the interior angle formula of polygon based on the number of sides of the polygon. They identify the missing angle using algebra.
Curated OER
Seeing Double
Students develop an intuitive definition for symmetry after viewing a PBS video. They examine asymmetrical patterns and demonstrate their knowledge by changing them to symmytrical.
Curated OER
Perimeter
Fifth graders create math word problems. In this geometry instructional activity, 5th graders define perimeter and discover how to find the perimeter of a rectangle, a square and a regular polygon. Students write word problems on finding...
Curated OER
Conic Sections and Locii
Students differentiate between ellipse and hyperbola. In this algebra instructional activity, students graph and solve elliptical equations. They use the cabri program to create the different conics and move them around.
Curated OER
Sketching Prisms
Students sketch and create nets of different polygons.In this geometry lesson, students differentiate prisms from other three-dimensional shapes. They define the properties of prisms.
Curated OER
Copy Cat
Pupils examine a Webmath page, and demonstrate how to copy and paste. They create a computer-generated template page presenting the attributes of two- and three- dimensional shapes.
Curated OER
Geo Jammin' - Day 4, Lesson 12: Geo Gee-Hawin'
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.
Curated OER
Give It a Whirl
Students examine and identify polyhedron shapes on a math website. They write journal reflections about two- and three-dimensional shapes, and transform a square into a pinwheel.
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
Exterior and Interior Angles of Triangles
Tenth graders explore the exterior and interior angles of triangles. They use a theorem in order to prove a theorem about all polygons. Students use the theorem and its applications to find the angles of different types of triangles.
Curated OER
Compound Locus
Students investigate circles and compound locus. In this geometry instructional activity, students identify the distance from a point to a line. They use Cabri software to create lines and circles.
Curated OER
Blindfolded Building
Students build a Lego design and then work with a partner to reproduce that design. They guide the building of the reproduction by description only and then check their work.
Curated OER
Lines of Symmetry
Fifth graders explore the concept of symmetry using lines drawn through different shapes. The worksheet that is included in the lesson should be used to chart the lines of symmetry for the different shapes drawn.
Curated OER
Fractal and the Dragon Curve
Learners explore Fractal designs. For this geometry lesson, students observe the different polygons created in nature and relate it to math. They define polygons on planes and rotate polygons about a point.
Curated OER
The Dragon Curve Fractal
Students identify the properties of a dragon curve. In this geometry instructional activity, students identify sequences and patterns as they solve fractals. They investigate patterns found in nature.
