Math = Love: Guess My Rule

### Guess My Rule

Late last week, I spent some time prepping for another first-week activity inspired by Elizabeth Cohen's Designing Groupwork: Strategies for the Heterogeneous Classroom (affiliate link to 2nd Edition / 3rd Edition).  It's called "Guess My Rule."

Y'all are probably tired of hearing me gush about this book, but I seriously learned so much about groupwork this summer from reading it.  It made me realize exactly why groupwork is beneficial, but at the same time it focused on why groupwork fails to achieve what you want and how to fix it. I think it's a must-read for any teacher who has students working in groups.  I bought the 2nd edition off of Amazon because it was cheaper, but I'm wishing now that I'd invested in the newer 3rd edition.
Just like for Rainbow Logic and Broken Circles (two other activities I'm also using the first week from Designing Groupwork), I created a task card to give my students with the supplies, objective, rules, and norms this activity is supposed to address.

Here's a non-glared version. :)

Here's what each group's supplies will look like:

There are three decks of cards.  1 deck of rule cards.  I printed these on regular white copy paper.  3 decks of shape cards.  I printed these on green, blue, and red card stock.  Shaun and I bought some of this Astrobrights primary colored card stock at Wal-Mart, and it has such great bold colors.  I love looking at anything printed on this stuff!

Each group will also need a circle made of string or yarn.

Since my desks are arranged in groups of four, this is how I would like to see my students set up for this activity.  One person will be the rule keeper.  So, they will get the deck of rule cards and the circle.  Each other student will have a deck of a different colored set of cards on their desk.

The red, green, and blue card sets are identical.  They are just printed on different colors.  There are circles, squares, triangles, and diamonds of 3 different sizes (small, medium, and large).  Here's what the template for each deck of cards looks like:

Here are the different rule cards that the rule keeper draws from:

I typed these up and formatted them so cards for two different groups would print on the same page.
Of course, you could always have students come up with their own rules.  But, I find that students need examples of what an appropriate rule would look like.

To give you an example of how it works, let's assume that the rule keeper pulled this card out of the deck.  Note: the rule keeper should place the rule card somewhere the other players CANNOT see it!

The students who are not rule keepers must decide which cards to hand the rule keeper.  When the rule keeper is handed a card, he/she will place it inside the circle if the card matches the rule and outside the circle if the card does not match the rule.

After a few minutes, the table might look like this:

If a student thinks that he/she knows what the rule is, they should ask the other players in the group for their opinion first.  After listening to what the others say, the player must make up their own mind about what the rule is and ask the rule keeper.  If the rule is right, the game is over.  If the rule is not right, play continues.  As time allows, other students can take a turn being the rule keeper.

This activity is supposed to reinforce three group work norms:

1. Find out what others think.
2. Tell why.

I look forward to walking around and eavesdropping on groups as they explain their reasoning to their group members.  My students need lots of practice doing this because it is something that many of them may have never been asked to do before.

After groups finish, I plan on having them complete this group reflection sheet.  Each person in the group will be responsible for writing out the group's answer to one of the questions.

I've uploaded all of the files I created for this activity here.  If you plan to edit the files, you'll need to make sure you also download the font HVD Comic Serif Pro.

Again, I can't recommend the book Designing Groupwork by Elizabeth Cohen (affiliate link to 2nd Edition / 3rd Edition).enough!  If you like this activity, you'll definitely enjoy the book!

1. Just out of curiosity, would you do this game more than once throughout the year? Also, how long would you give them to play it the first (or only) time around? Thanks for always sharing awesome stuff!

1. I'm not sure. We'll see after I use it for the first time next week. :)

2. I love that book, too! I think I have the first edition... I used broken circles on the first day of school. I loved the conversations about how the whole group has to participate and everyone had something to offer. Great way to set the stage for group work!

3. I've been following your posts on this book all summer. I just finished two grad classes yesterday, so now that I have some time I broke down and bought this. I can't wait to dig into it!

1. I think you're going to love it!

4. I read your post on Broken Circles while we were on a driving vacation from Denver to Minneapolis (so I could go to TMC!!). So I bought the books somewhere in North or South Dakota (I'm embarrassed to say that somehow I didn't notice that they were different editions of the SAME book, I thought you had read both!). Anyhow I'm in Ch 9 of the 3rd edition and I think it's great too. My school is doing Broken Circles on day 1, thanks to your post!! I can't believe you've done all the prep work for so many other of the tasks, if I make any modifications I'll let you know!! Basically this is a HUGE THANK YOU for your posts and for sharing everything. I'm also almost done reading Building Powerful Numeracy for Middle and High School Students by Pam Weber Harris-have you read it? I really like it-it's on Number Strings and more. Thanks again, Debbie

1. Sorry about the edition confusion! Glad to hear you're enjoying it, though! I haven't read Building Powerful Numeracy yet, but it's on my wish list.

2. I just bought it for you - as a huge THANK YOU for all you do for me, and all of the other MTBoS people your blogs inspire!

3. I'm sending it to your school, so look for it, hopefully next week!

4. That is awesome! I too am very thankful for you sharing all your work, Sarah!
