  6. Everyone got to see the fun sticky stuff we will be using to make the window.

We accomplished a lot you guys!  Good work!


  1. DO YOUR SKETCHES.  We didn’t have time to assemble them today, but we need to do that when we come back.
  2. Do the next three worksheets (“Interior Angles of a Triangle”, “Exterior and Interior Angles of a Triangle”, and the sheet that only has four questions on it)
  3. You will have quizzes on this information to make sure you are ready to prove what you need to prove for your project.

Next Class

  1. Answers to the worksheets.
  2. Quiz on how to use what we have learned for our projects.

Geometry = News and Holidays

We made a good start on the projects!  I am SO excited!  I think you guys are going to amaze me and yourselves with how quickly you will accomplish this task!  I can’t wait to see how you make this happen!

Math exams are done, so I’ll have those graded before the week ends.  I can’t wait to see how you did!  I talked to a few of you and was very encouraged to hear that you thought it was long, but not hard.  That’s good news!

Take a break from math!  I know some of you will have things you need to do over the holidays, but let your Informal Geometry brain rest up for the stained glass windows!  Come back ready to tackle this thing before the end of January!  We can do it!

Thanks to those of you who already sent summaries of your group’s work.  You do not need to do that before we get together again.  If you haven’t sent it, don’t!  We’ll take care of it later!

The Coffee Talks were fabulous!  It was so great to talk toy ou guys outside of the classroom over a cup of coffee (or whatever…  I learned some new drinks with you 🙂 ) Thanks for the insights and the encouragement!
