Which One Doesn’t Belong

Last year I was introduced to a great website called Which One Doesn’t Belong by my friend, Nancy Minicozzi. The site is full of visuals in which students must decide which of the 4 images doesn’t belong.

Looking at the following, which would you say doesn’t belong?


Based on your perception you may have said the heart because it is the only one that is NOT a polygon. Or perhaps you thought the star for the lack of the red outline. Possibly you were drawn to the green arrow as it is comprised of two different shapes. Or maybe it was the last shape because it lacked a color on the inside. No matter what you thought, you were right.

This is a fantastic, low-risk activity for students to participate in. I have done it a few different ways. I have had students study the image and then move to different parts of the room. While gathered there, they talk about why they chose the image they did. Other times I have used tools like Padlet for them to record their thoughts. No matter what method I use, they enjoy the activity.

This year I have 1 non-English speaker. At first, he was reluctant to participate, but now he regularly raises his hand to explain why he chose the image he did. I also¬†have students moving from table to table because they can see how the different images don’t belong.

In addition to the low-risk appeal, I am able to teach my students how to have conversations. We begin sentences with, “I agree with…. because…”, or “I disagree with… because…”, or even better, “In addition to what … said…” Quality language, thought process, and communication skills that are being utilized daily.
