= The Pirate Ship Tessellation = ==** There was a tessellation project in my math class. What is a tessellation? A tessellation is an endlessly repeating patterns of interlocking shapes. Tessellations have been around or thousands and thousands of years. My shapes in this case, are pirate ships. There are three types of tessellations, rotation, translation, and reflection. I ended up doing the reflection and rotation tessellation because when u look at it u see reflection, and if u look at it in groups then u will be able to notice the rotation. **== ==** The steps to doing tessellations can be difficult. You have to pay attention. The way you do a reflection tessellation is, take a piece of good construction paper, and make a grid on your paper by making a mark at every three inches along the top and bottom. Then take a ruler and connect the lines together. Then repeat the same thing except on the sides. Once you have done your grid, take a three by five index card and measure the top and bottom three inches, make a line. Then cut the card at the line so you have a three by three index circle. **== == Then you take the index card and place it in one of the squares on your grid and make sure it fits. Then once you are done, draw a line from the bottom right corner to the bottom left, make a design. N ext, from the bottom right to the top right corner, make another design. The cut along the lines and you will have the two separate designs that you made. The you take your pieces and flip them and drag them straight across your index card. Tape them down making sure all your corners are matched up. == == Once you are done place the design on your grid, matching the corners of the original index card to the corners of the grid marks. Then trace the design. Next, flip your design over and drag it the way you dragged your cut pieces and then trace again. Repeat this pattern until your are done your full grid. Once you are done you can color your grid and the designs in it. It will have no gaps in it if it is done correctly. == ==** The symmetry that my tessellation that mine ended up being is S symmetry because when you turn it you see the same thing every time. When you turn an "S" it looks the same when you keep turning it. That is what my tessellation does when you keep turning it, it moves like an "s". For the design description, the tessellation that i did was a pirate ship, my teacher said every time she looks at it she thinks of stained glass. Every time you look at my tessellation you will see that it rotates in groups of four, but if you look at it really quick you will see reflection. That's how my tessellation is rotation and reflection at the same time. **== == That is how a tessellation is made. You have to be very careful that all of your lines are matched up and they fit with the other shapes that you traced. you will have no gaps when you are done, id=f you have done it correctly. Your tessellation will look good when you are done. I promise. Good luck and enjoy making your tessellation. ==
