2014 Pictures

by Jon Orr

This morning I read a blog post from Jonathan Claydon on 180 blog posts. I’ve learned lots of class/math ideas this year from reading 180 blogs and I loved his ideas on 180 days of pictures. My goal next year is to start posting 1 pic for each day. It would be a great thing to show the students at the end of the semester too!

here are a few pictures from this semester.

Commit & Crumple!

by Jon Orr

Saw this activity in a book I picked up at the NCTM conference a few years back (Philadelphia).

This book has been great for engaging activities in math….here is the one we did today:

Commit & Crumple
We are reviewing for our exam and I wanted to review average rates of change and instantaneous rates of change. I wanted to see what they remembered…and also how they remembered the graphical representation of rates of change.

Game of Risk

by Jon Orr

Recently read a blog post of a review game …. Risk from Angie (@aeakland) . I love review games instead of just textbook questions…..so i adapted this game to be played in my MHF4U Advanced Functions class.

Here are the rules….

  • In teams, each team starts with 100 points. Write your points and names on the board.
  • Complete any of the Risk Questions in any order. (They are just the Review questions from the textbook).
  • For each question: After coming up with a solution, wager any or all of your points.
    • If you are correct – – add the points to your total!!! Yay!
    • If you are incorrect — subtract that many points from your total. Boo!
  • The top three teams with the most points were eligible to enter the draw at the end for the prize!!!

Great things about the game…

Kids were cheering — when getting the problems right!……that doesn’t happen when just working on review problems from the book.

Kids were self /peer assessing their work — by betting they were deciding how confident they were on their work! They took their time, and thought about their answers making sense!

Kids were doing math!

The winning team won their choice of a geek sticker!

The Internet in Real Time

by Jon Orr

Love this info graphic…..posting it here to remind myself about creating a math lesson around this. Lots of possibilities. Let me know if you have one?

So far… “Pick a stat, show how it’s changing with respect to time in a graph, equation, table”.
