Transformations and Tessallations.

Wednesday Oct. 6, 5th, 6th, and 8th period geometry:

You should have been given a paper with shapes on it as you came in. Right away, get scissors from one of the silver bins, and cut out the shapes. Hang on to them.

In class,

• Arrange the shapes on your grid paper to find a repeating pattern (tessellation) – your pattern must include at least two different types of regular polygon. If there is another shape included, that’s fine, as long as there are two different regular polygons.
• Trace the shapes to repeat the pattern across the whole page of graph paper.
• Find at least two examples of different geometric transformations (reflection, rotation, translation, or dilation).
• Use a marker to outline the two examples of transformations (one shape for each)
• Use a ruler and protractor to figure out the transformation rules, and write the rules on your paper (choose two).

When you are finished, turn in your tessellation. Then, work on the transformations homework assignment. If you need another copy, get one off the table in the front of the room. This is due next time.

If you need practice with the transformations, use the websites below:
