Lesson in Tessellations


My name is Rosita Alston-Grissom. I teach at a top notch school in Augusta -Richmond County.

Here you will see my students work and get a preview of the world of glides, rotations, reflections, and translations. Before you think that this is a gymnastics lesson, take a look at the beautiful pictures which we have in store for you.

This tessellation is by Jalpa Patel and she has named her work Eagle Heads.



This tessellation design is called Women in Color. It was designed by Luan Liao, a junior who designed this in her spare time.



This picture was unique because it had a new idea. It looked like a horse's head or a chess piece. Cassaundra Johnson, the creator, named her work appropriately--

Horses ' Head.


This tessellation is by LaToya Franklin. I am willing to bet you know why she named it -- Froggy!



The following lesson is about tesselating.


This is a simple lesson on tesselating a square by a glide translation.

Before we begin, we need to have certain materials: patty paper, pencil, and square grid dot paper.

Step 1:

Place square grid paper on top on your desk. Overlay your patty paper on the dot paper. Trace the dots at the top left of the paper that form a square.

Step 2:

Place your patty paper to the side. Make a design on the square grid paper between the two uppermost left dots. Place the patty paper back on top.

Step 3:

Trace the design between the two left dots on your patty paper after lining up the dots on your square grid paper with your patty paper dots.

How are we getting along????


Step 4:

Slide your patty paper to the left lining up your right dots on your patty paper with the left dots on your square grid paper.

Step 5:

Trace the design again. Good Job!

Step 6:

Place your patty paper to the side. Make a design on the square grid paper between the two uppermost dots. Again place your patty paper on top and trace the design.

Step 7:

When completed, slide the patty paper up, and trace the design between the lower curves. This is your tile.

Create a design like the others with tracing paper cover your patty paper. It should fill the paper and be your own unique creation.

Thanks so much for your attention.
