Sorting Rocks and Guess My Rule

During Science, we revisited the concept of sorting. This time we sorted our river rocks. Students worked with a partner and figured out a rule that they could sort their rocks by. We continued working with this concept in math. First we started by sorting buttons. Students had to come up with a rule or attribute to sort them by. Some students rules were: buttons that have two holes, buttons that are shiny, buttons that are black, buttons that are colorful. We continued working on the concept of sorting by an attribute all week long. As an assessment, students cut out shapes of different colors and sizes and recorded their rule. We had to guess each student's rule and check by flipping up the card on the front of their creation.
