Today I am sharing Odd One Out with Polygons. This is the fourth one-page geometry printable I have shared on my blog this month. To download the free Google Doc, click here.
This page will give you two sessions of the activity. I put my students in groups of three or four and gave them half of the printable above. They needed to discuss which shape they would leave out of the group of four and justify their answers. They listed the shape they left out and their reasons why on a sheet of notebook paper. Then they discussed why another shape in the group might be the odd one out.
For example, in the top group, a student might say that the pentagon is the odd one out, because it has an odd number of sides. Students then move on to discuss another shape.
Update: these are available in my 22 page paid product at TPT and TN.
