Stephanie at Teaching in Room 6's idea and I love it!! At my school, we always receive way too many Book Club Order forms. Well, I saved them up. Then I printed Stephanie's activity that you can find here for free. My Grade 4's worked with a partner but they each recorded the specific books, quantities, and totals that were as close to $200 as possible but not over it. Every single student was engaged for the duration of this activity. Here are a few pics of my lovelies hard at work.
Here's hoping you have a fantastic night!
