## Great Classroom Action

Jennifer Abel creates a promising variety of card sort activity:

Basically, after dealing the cards, the basic idea is for kids to pass one card to the left while at the same time receiving one card from the player to their right. The object of the game is to collect all cards with the same suit/type/category. Here are two examples that I recently created for next year.

Julie Morgan offers three sharp lesson-closing activities. My favorite is “Guess My Number”:

I choose a number between 1 and 1000 and write it on a piece of paper. Each group takes it in turns to ask me a questions about my number. The questions can vary from “is it even?” to “what do the digits add up to?” to “is it a palindrome?” (my classes know I like palindromes!) When a group thinks they have figured it out they write it down and bring it up to me. Each group is only allowed three attempts so cannot keep guessing randomly. I like this for emphasising mathematical knowledge such as multiples, primes, squares, etc.

Pam Rawson contributes to #LessonClose with both a flowchart that illustrates her thought process at the end of classes and then some example exit polls for both “content” and “process” objectives:

As a member of the Better Math Teaching Network, I had to come up with a plan – something in my practice that I can tweak, test, and adjust with ease. So, I decided to focus on class closure. Since I don’t have an actual process for this, I had to think intentionally about what I might be able to do. I created this process map.

Robert Kaplinsky offers the #ObserveMe challenge:

We can make the idea of peer observations commonplace. It’s time to take the first step.
