Students will look at the Shape choices on each slide. Students will use Comparing and Contrasting skills to make a claim and then defend the choice that they make with evidence. They must decide which shape isn't like the other ones and doesn't belong and be able to prove it by citing evidence. There are learning opportunities with 2D shapes and with real life 3D shapes.
The learning activity can be used with a projector system for the whole group to discuss as a mini lesson and then it could be done in small groups with printed cards. It also could be made into flash cards and used at centers independently or with a partner. When making a center, printing 2 cards or 4 cards to a page works well.
A differentiation task opportunity would be provided for students who are ready to compose their own compare and contrast shape set. There are cards started to help students get the idea of how to think about setting up a set. They must verify that 2 fit together and the third one doesn't fit. Another opportunity is for students to use the card that is completely open ended to create their own set. They are responsible for setting up the entire task and proving that it is valid.
When students create, organize, construct, justify, verify, and defend they are working at higher/deeper levels of thinking.
This learning task can be in a math center several times a year, year after year giving this purchase lots of mileage and longevity.
