Lesson Synthesis
Lesson Synthesis
“What important things did you consider as you created the image for your How Many Do You See? Why were these things important?” (We thought about the ways to arrange the dots, so they could be grouped to help other students count them. We thought about how many dots were in the groups, because if they were too big, other students wouldn't have time to count the dots in a short amount of time.)
