#### Polygons

For Teachers 2nd
Second graders view a PowerPoint presentation on Identifying Polygons by their number of sides and their individual properties. They separate polygon tiles into groups by their attributes.
Lesson Planet

#### Polygons

For Teachers 6th - 8th
Students work together to create mobiles with different polygons. They research the polygon and list its characteristics. They may present to the class if they chose to.
Lesson Planet

#### Don't Box Me In

For Teachers 4th - 6th
Learners explore the relationship between flat and three-dimensional shapes. They identify the names of 3-D shapes and construct cubes from squares.
Lesson Planet

#### Words in the News: Venezuela Plane Crash

For Teachers 6th - 12th
Learners discuss what can go wrong during a plane flight. In groups, they work together to match new vocabulary words to their definition. They read an article about a plane crash in Venezuela and answer questions.

#### 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.
