Math = Love: Playing Spot It! In The Classroom

### Playing Spot It! In The Classroom

During the last few weeks of the school year, I started to run out of ideas for my weekly brain teaser.  Last summer, my sister had introduced me to the game Spot It!  It's a set of circular cards that come in a metal tin.  The object of the game is simple.  Sort the cards into two piles.  Each player flips over a card.  They have exactly one item in common.  Be the first to spot it.  Win both cards.  Repeat.

As simple as the game sounds, it can be quite tricky when actually playing it!  Often, my sister and I would stare at the cards for ages.  Once we finally found the item in common, we would feel so silly.  Once you see the common item, it seems obvious.

The game is manufactured by Blue Orange Games, and they have a playable demo version on their website.  (They also have an NHL version you can play on their website, too.)  One Thursday, I put the demo version up on the Smart Board for my students to play for the first five or so minutes of class.

Originally, I thought I would ask for two volunteers who wanted to compete against each other.  Each person would go up to the Smart Board and play a round.  The person with the most points would win.  I found that my students in the audience couldn't quite keep their mouths shut, though.  As soon as they spotted the item in common, they wanted to shout it out.

If I was going to do this again as a quick class opener (or time filler), I would break the class into two teams and let the audience participate.

My students really enjoyed this quick class opener.  Of course, they would have played all hour if I hadn't stopped them after five minutes so we could get busy learning some math!

I'm thinking there has to be a way to remake this into a math game.  Any ideas?

1. I've never played this game, but now I need to find it and play!

How could you turn it into a math game? Since I teach middle school, I'm thinking that there could be answers an integer operations on each card. You have to find the problem and the answer that match.

For instance:
Card 1: 4 -7+5 -3 6-1 7 9-(-4)
Card 2: 7-4 5 -4+6 8 2-6 12

Would that work?

1. Ok, so the spacing went away:
Card 1: 4; -7+5; -3; 6-1; 7; 9-(-4)
Card 2: 7-4; 5; -4+6; 8; 2-6; 12

2. I like how you think!

2. I don't know about a "math game," but there are certainly math questions about the game to be explored! Like... If there are eight objects on each card, and every pair of cards has exactly one object in common, what is the greatest number of cards there could be in the deck?

It's tricky, but thinking about it with fewer objects per card (like 3 or 4) might help.

1. Very good point!

3. Takes a bit more time, but... Three quadratic equations (vertex, factored and standard forms) and a graph on each card.

1. Oooh - this could be interesting!

4. Simplifying expressions (including radicals), factoring quadratics, linear equations in standard and slope-intercept forms, solving equations... But I imagine these would all take a lot of time to create!

1. I'm thinking there has to be some way to automate the making of the cards from an excel spreadsheet. Something to ponder. All great ideas, though. Thanks!

5. Sarah--I really enjoy your blog. You might want to look at Set and Swish too which are also pattern recognition games. Another game for your class might be Albert's Insomnia.

1. Thanks, Ginger! I adore Set and Swish! I'm going to have to look into Albert's Insomnia, though.

6. Just saw this blog. Here is a Spot-It generator to create your own spot it game.
