Raise your hand if you have ever seen a tessellation!

What is a Tessellation?

a design that uses repeating shapes that fit together without overlapping or gaps.

Every day tessellations . . .

Tiles are tessellations.

Quilts can be tessellations too!

Can you think of other tessellations?

What about a grid?

Or a wasp nest?

Wasp nest? Let it be - the best answer!

Tim Gibb, Insect Diagnostician, Department of Entomology, Purdue University

Several species of wasps, including paper wasps, yellow jackets and hornets construct gray, paper-like nests made up of wood or foliage chewed up and elaborated by the insects. Regardless of the species, all colonies of these wasps have two things in common; (1) they can sting very effectively and (2) they are beneficial insects because they eat spiders and other insects that are potential pests. These two seemingly opposite characteristics make the call on 'should I destroy the wasp nest in my yard or let it be?', a difficult decision.

By leaving the nest alone a homeowner can decrease the danger of being stung while trying to kill the wasps, save on the chemical cost of controlling it, and increase the natural pest control in the yard. In cases where the nest is located in a wall void or in a building, by leaving the nest alone, a homeowner can save the costs of breaking into the wall to remove the nest.

Assignment 1 Draw a tessellation using a 4 sided polygon.

The design must be 6” x 6” You must use a ruler to measure and draw straight lines Color your design with a pattern (repeating colors) Assignment 2 Draw 1 of the 11 basic tessellations Use the tessellation worksheet examples You must use a ruler to measure and draw straight lines Color your design with a pattern (repeating colors)

How to draw a geometric Tessellation You will need a – Ruler – #2 Pencil – Eraser – 8x11 paper

First

Find inches on your ruler Most rulers are 12” Inches This example is 6 inches long inches

Second

Find 0 on the ruler 1 inch 2 inches 0 Do you see the pattern?

With the 0” at the edge of the paper, use your pencil to mark 1”, 2”, 3”, 4”, 5” and 6” 0 Does the 0” line on the ruler touch the edge of your paper?

Put marks at the top of your paper

0

To make sure the lines are straight, do the same thing at the bottom of your paper.

Does the 0” line on the ruler touch the edge of your paper?

Use your pencil to mark 1”, 2”, 3”, 4”, 5” and 6” at the bottom
