After viewing work from our last "black-out day", I could tell that many students had not mastered the concept of multiples, especially not comparing multiples of different factors. We completed this whole group task to review the material again. Each student had a multiple and we decided together which area of the Venn Diagram the multiple would be placed and students were given the opportunity to reason out loud and discuss why they thought their multiple would go in a certain section of the diagram. Our headings for the diagram were the factors of 2 and 3. If the number was a multiple of both factors, students placed their card in the center and if it was a multiple of neither, we placed it to the side. We used hula hoops for our Venn Diagram and completed this task in the hall since we didn't have enough space in our classroom.
