Ahhhhh March, we meet again.  Testing season is officially just around the corner.  As you begin reviewing for End of Course exams, I wanted to share with you a favorite strategy I used with my students to incorporate critical thinking.  It's so versatile, and if you have a class set of whiteboards, very easy to use!  It's called Odd-one-Out.

Students will choose between 4 terms, numbers, graphics, etc. that is not like the others.   I like to choose ideas to put in the boxes that have more than one answer, to require students to think more critically.  To start, I draw a 2 x 2 grid on the white board and label the boxes A - D.  Students write their answers on their white boards, explaining thinking.     

There are so many applications with this strategy!  Start by writing 4 terms in the boxes.  I like to think of words with interchangeable parts of speech based on usage in the sentence. 

Try this one!  Based on how your students think of how numbers relate, they can come up with various answers!  

I'd love to hear how you've used this strategy with your students to prepare for testing or to review concepts.  Please share in the comment!
