This is great activity for an engagement or intervention. Students groups the pictures on the card sort into "like" categories. This activity was created to show students that elements in the same group, share similar properties. Rather than jumping right into the abstract concepts of the Periodic Table, students will use everyday known objects to create an understanding of characteristics and properties. This activity has an extension option for advanced placement students who like more of a creative challenge. There are three components to this activity- cards, teacher page, and a student handout. recommendation- I printed the pictures on card stock, cut them out, and placed them into baggies for each group of students to use. Group students in pairs, 3, or 4. I have about 40 different manipulative like this one for 8th grade science.
