Francis's growing post

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 the process of turning the center of an axis. Reflection symmetry is a two-dimensional figure, so it’s a reflection. Pentominoes are shapes that are formed with 5 squares and the corners don’t touch the squares go beside or on top and under. Pentominoes relate to reflection symmetry because if you look at it pentiminoes are a two-dimensional figure and it can be reflected of a mirror.

2. Create a pattern. You must represent this pattern 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 occurring with your pattern and if your pattern has an ending or if it continues indefinitely. Make sure that your explanation is clear enough that the person reading your description could understand your pattern without seeing your diagram.

My pattern goes up 1 block or square on the top and 1 on the end of L shape.

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.

Your description of rotation and reflection aren't very clear. You never said what a reflection was, or how to create a reflection. Second does a pentominoe change if we use rotation and reflection?
Next does you pattern continue on forever?
Finally can you use numbers more effectively to help describe your pattern? Should you maybe inform the reader as to how big or how many blocks are in the starting shape?

Good effort and with a few modifications this would become a much better post.
