While introducing this concept to the kids, I started by talking about how they can "help us reach our goal" of beating the bomb. I asked questions like "will standing, and counting down help us reach our goal?" They answered with a resounding NO! "Would checking the floor help us reach our goal?" YES! The first time or two, it was a little loud, but I started walking around, quietly mentioning things like "Ooooh, I see a marker under the red table." They noticed that if they listen while they clean, I will mention everything that needs to be done by the time the bomb explodes. I also made sure that the last item on every clean up list is that they are sitting quietly in their seats. This avoids the while class counting down at the top of their lungs.
If the kids "beat the bomb," they get a point on their scoreboard; if not, I get a point. I also found the scoreboard in the gallery, and the HOME and AWAY labels can be changed to whatever you want it to say.I have a SMART Notebook file for each day, and have the bomb, clean up lists for drawing, painting, and clay which can be moved within the slideshow depending on which materials we are using that day. Then I have a slide for each class' scoreboard. At the end of the day, I hit save and we continue each time the class meets. I told the kids they would get a "mystery prize" at the end of the year if they have more points than I do.
Since starting this, the kids have gotten very excited about clean up. Half way through the class I'll get "are we going to do the bomb again today?!" The kids are excited, and working as a team in a way I never imagined they would! It's astounding! My biggest issue now is getting them to slow down so they don't get hurt!
I've also found some interesting ways to get them lined up using my SMARTboard, and keep these slides at the end of each day's slideshow. There is a "color chooser" which shows a different color every time it is touched. I tell them if they are wearing the color it shows, they can line up. There's also letter dice that I changed to have only vowels; then I select either their first or last name as say if they have that letter in the chosen name they can line up. Finally, there is a coin flip. I have them choose heads (put their hands on their head) or tails (put their hands on their butt) and flip the coin. The correct guess lands them in line.
