SMART Board Goodies A Resource Blog by Amber Coggin 

I found this nice estimation activity on Transum.org. Students are asked to estimate the number of sheep in the field, then enter the number. I normally look for activities that require little use of the keyboard, but the teacher could sit at the computer and enter the students’ answers, or the onscreen keyboard is always an option. Once you click next, it will tell you the exact amount of sheep in the field, and also give you some other stats including error percentage. There are many interactive math activities on the site, so please  check them out as well!
