Hi Deb, Thanks for your question. I don't have one, but I thought what a neat activity that it would be to have the kids work on this as a project to make up some!!! If you give it a try, let me know how it goes. I think they would learn a lot about mental math. >I used to have an activity for upper elementary that was excellent.

Then you would put this long, like 10 or 12 step problem on the >overhead, and tell them to solve (evaluate) the problem and raise their >hand when they were finished. And if you used your brain, you could get >done much more quickly than if you punched in all the numbers on your >calculator. >So I wondered if anyone has an activity like that, that would be >appropriate for middle level. >Thanks.
