They had yesterday to prepare the presentations, and today to present them. Mr. Helmuth said overall he was pleased with how they performed, and that they understand the concepts he's been teaching.

If you want extra credit for reading and discussing the blog today, tell the adult you are reading this with what you did for your presentation. Tell them whether you thought it went well or not. Then, find a scrap of paper and write a sentence from the discussion. Have the adult you read and discussed with sign the paper. Turn it in on Monday. Make sure your name, date, and hour are on the paper.
