## Outcome E1

Identify the first 5 regular polygons and understand basic properties (number of sides, lines of symmetry, and definitions of geometric terms).

Class Activity:

Students create vocabulary booklets using Power Point. They explained the geometry term and also included a picture.

Students found www.

Class Activity:

We used our trial memberships with www.IXL.com to assess our ability to meet this outcome. Each student in the class has his/her own personal username and password. (This can be used from home!)

## outcome e3

Determine (through investigations, using concrete materials and technology) the characteristics of shapes that will tile the plane with a reflecting pattern.

Class Activity:

Students using pattern blocks to discover which regular polygons will tessellate a plane, that is which combinations of regular polygons will completely surround a point.

Prior Knowledge for this activity:

Students using pattern blocks to discover which regular polygons will tessellate a plane, that is which combinations of regular polygons will completely surround a point.

Prior Knowledge for this activity:

- Students needed to know that there are 180 degrees in each triangle.

- Students needed to know how to triangulate a polygon, that is, to find out how many triangles were in each polygon.
- Students multiplied the numbers of triangles in their polygon by 180 degrees to find the total sum of the interior angles in that polygon.
- Students then divided the total sum of the interior angles by the number of vertices to find out the measure of the interior angle at each vertex.

## Outcome E4

Create designs involving tiling patterns (e.g. Escher-type designs, wallpaper or fabric designs), using technology (e.g. dynamic geometry software, design or drawing software).

Class Activity:

Students using the software program Tessellation Exploration to create their very own tessellation. They were able to make it their own, by adding eyes, mouths, ears, wings, feet, scars, etc.

## Outcome E5

Analyze the geometric aspects of logos and design.

Class Activity:

Students completed a "google" search to find existing logos. We examined symbols such a Audi (translations), Honda (reflection), Acura (reflection), Mitsubishi (rotation), for various design elements.

## Outcome E6

Create a personal logo, using the mathematics of symmetry, translations, reflections, rotations, or dilatations with the aid of technology.

Class Activity:

Students were able to choose from the following design projects:

a) Create your own tattoo

b) Create your own personal business card with a logo representing who you are

c) Create a logo for a business/ company you aspire to own

Designs must include 2 transformations (slide, flip, turn or dilatation)
