Getting third graders to read a word problem and think about what to do rather than to just assume they know (which usually means adding whatever numbers are there) is quite a challenge. So today we tried out some numberless ones (thanks to Brian Bushart) and it was a serious hit. My kids had white boards and set up problems before seeing any numbers. Then as numbers were revealed they put them in. Everyone was engaged. Tomorrow we’ll try some more and see if this level of excitement (and thinking) holds.
