Polygon Search

For Teachers 3rd - 8th
Students investigate a variety of two-dimensional polygons which are divided and combined to determine various properties. The figures are compared, contrasted, and classified.
Lesson Planet

Castles

For Teachers 10th - 11th
Students create a scale model to a castle using the dimensions they were given. They calculate the surface areas and volumes of each section of their castle.
Lesson Planet

Tunnel Traps

For Teachers 1st - 3rd
Young scholars identify shapes that match specific shape descriptions involving a range of geometric terms and correct polygon names. They utilize a mathematics educational software program to gain practice.
Lesson Planet

Who Am I? (Middle School)

For Teachers 3rd
Third graders complete a classroom game used to build understanding of two and three-dimensional shapes. Diagonals, sides, regularity, congruency, angle measurements, parallels, perpendicular, faces, and edges are a few of the vocabulary...
Lesson Planet

Around and Around We Go

For Teachers 4th
Fourth graders discover that a polygon is a closed figure formed by line segments, and that the perimeter of a polygon is the sum of the lengths of its sides. They utilize a worksheet imbedded in this plan to gain lots of practice with...
Lesson Planet

Mystery Polygon

For Teachers 2nd
Second graders describe a polygon in the form of a riddle.
Lesson Planet

Polygons

For Teachers 4th
Fourth graders identify and describe lines, shapes, and solids using formal geometric language. They use Inspiration to create a graphic organizer and outline of polygons.
Lesson Planet

Congruence Theorems

For Teachers 7th - 10th
Students use an applet to explore the conditions that guarantee uniqueness of a triangle, quadrilateral, or pentagon, regardless of location or orientation. Each set of conditions results in a new congruence theorem.
Lesson Planet

Mimicking Nature; Science, Aviation, Flight, Wings

For Teachers 6th - 9th
Students consider the relationship between form and flight and investigate the history of man made flight and how wing shape and flexibility affects the maneuverability of an aircraft.

Tessel Your Way to Nagano!: Olympics, Winter Sports, Snowboarding, Graphic Design, Geometry, Math, M.C. Escher, Tessellations

For Teachers 4th - 6th
Students create Post-It note fundamental regions to tesselate. They make tesselations using computer software or websites. They create a jacket design with tesselation and determine the cost of production.
Lesson Planet

Two-Dimensional Objects

For Teachers 1st - 2nd
Students identify two-dimensional shapes and explain the similarities between two-dimensional shapes. They construct their own square and rectangle. They then share their shapes in small groups because every shape be a different size.
Lesson Planet

Lines, Rays, Line Segments, and Planes

For Teachers 9th - 12th
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
Lesson Planet

Geometry in Tessellations

For Teachers All
Students examine tessellations and their geometric properties. Students also develop a better understanding of lines, planes, angles, and polygons.
