More or Less

One of our Daily 5 Math mini-lessons today focused on comparing two groups of numbers and determining which group had more or less than the other group. Students took turns coming to the board and creating various numbers of objects in either box. The class then counted the items in each box and determined which had more and which had less. I then asked the class which box A or B had either more or less. Before moving on to the next set of numbers, one student was chosen to explain how he/she knew one box had more or less.
