Getting Ready

To prepare this activity, I simply printed the cards onto cardstock and cut them apart.

Then, I laminated the cards to make them last.  I knew this activity would be a math workstation that my first grade students would want to use over and over again!

Which One Doesn’t Belong?

To teach my students how to play, I gathered the group together on our classroom carpet.  I told them that Which One Doesn’t Belong? was an out-of-the-box brain game where a student points out the item she thinks doesn’t belong in a grouping.

I put up an example card with various shapes on it and explained that there were multiple correct answers.  An item could have a different color, size, shape, or value that would make it not belong.

I randomly selected a few students and asked them which one they thought didn’t belong and WHY!

Next, I had my students partner up.  I passed out one card to each pairing and I gave them a few minutes to practice talking about what they noticed.

I walked around and loved what I was hearing!  Students caught on quickly and were able to give reasons for their opinions.

Lastly, I had some students share their thinking and then I put all of the cards into a math workstation.  I told my students they could continue to use the cards during math time by partnering up with a friend and asking each other “Which one doesn’t belong?” and “Why?”

I loved getting students thinking about math ideas and math vocabulary with ease.
