Today the students were working with partners to determine if math equations were equal or unequal. They worked together to prove their equations with drawings and other mathematical thinking on large chart paper. As always, the children enjoy working with their partners on investigations. As I walked around I could hear students talking together about how they were solving the equations and noticing when each other made an error in thinking. Then they worked together to fix it. I was so impressed with how the students challenged each other in this activity.
