Camille's Growing Post

Hi Mr. Reece!!! Please check my growing post again, because I put some changes on it. You can easily see it because I put my changes into a colour Red.

Thanks Mr. Reece!!
Have a nice day :)

1.) What is meant by the terms "Rotation Symmetry" and "Reflection Symmetry"? How does this relate to pentominoes? Explain these terms so that anyone who reads your post understands what you mean.

Rotation Symmetry is a figure around a center of fewer than 360 degrees and the figure appears unchanged. If you rotate or flip a pentominoe, it is still the same shape as the other one.
Reflection Symmetry ( sometimes called Line Symmetry or Mirror Symmetry) is easy to recognize, because one half is the reflection of the other half.These relate to pentominoes because it starts in 5 squares.

2.) Create a pattern. You must represent this pattern both pictorially (i.e. with a picture or diagram) and with numbers. You must show the first 4 steps of your pattern.

Shape #1

Shape # 2



Shape # 3

Shape #4

3.) Describe in words what is occuring with your pattern and if your pattern has an ending or if it continues on indefinately. Make sure that your explanation is clear enough that the person reading your description could understand your pattern without seeing your diagram.

My shape is a letter L. My first shape has 5 squares. You keep adding 1 square at the top and 1 square on the bottom right every step. So if you add 1 square at the top and 1 square on the bottom, the letter will be longer and higher. You can do it again and again in every step (like forever).

4.) Create a T-Chart that shows what is happening with your pattern. You must show the first 4 steps of your pattern with the T-chart.

Great job so far, but I have two questions. If I rotate or flip a pentominoe does it change? second does your pattern have an end or does it continue on indefinately?

Great job with the post and making additions based upon my comments. This post deserves 19/20
