According to Merriam Webster Dictionary, a tessellation is:  a covering of an infinite geometric plane without gaps or overlaps by congruent plane figures of one type or a few types.

Here are some examples of tesslations that students created.

Taking a Closer look at Paper and Plastic Bags



We've spent the last two days breaking down the differences and similarities between paper and plastic. Using the informational visual to the right, we read about consumption, production, pollution, recycling, and whether either is biodegradable.
Throughout this experience I've thought about my consumption for both paper and plastic. When I go to the grocery store, I generally ask for plastic. I reuse the plastic bags for garbage can liners, a bag to take my lunch in, as well as bags to have in the classroom in case students need to bring things home. I'm personally going to make an effort to try and reduce the amount of plastic bags I use by purchasing a reuseable bag for groceries. I'm not ready to quit using plastic but if I can limit my use, I know I'll be making somewhat of a difference.

What do you do with paper or plastic bags at home?
Do you use a reusable bag? If so, how often do you use paper or plastic?
What unconscious behavior (things you do that you don't notice yourself doing) do you catch yourself doing that you'd like to change (with paper or plastic)?

Paper, Plastic, or Neither?

 
Imagine going to the grocery store and NOT hearing the question, "Would you like paper or plastic?" The longstanding debate over whether to use plastic or paper or neither is an issue we will be tackling over the next several weeks.  Students will be learning how to do the following:
  • Write persuasively.
  • Research and gather information to support ideas.
  • Form opinions.
  • Make decisions.
  • Plan
  • Inspire
  • Debate
