I absolutely love reviewing on our desks! The kiddos are always so surprised when I tell them they'll get to write on the desks! There are so many things that I like about doing this....
1) Easy set-up
2) Easy clean-up
3) Minimal materials
4) Each kiddos gets their own defined space
So, so easy!
Basically, I put a problem (or problems) on the board and set the timer. Students work through the problem. Sometimes I require they use a particular strategy, sometimes I let them do whatever they are the most comfortable with.
Next, I call kiddos up to explain their methods.
I know that it sounds like the same kids will win every time, BUT... each leveled group has a color name. I assign each color group a different set of problems based on their ability. I aim to have a winner from each group. It works out really well and over time, every single student wins!
