Our school gives timed tests on a regular basis (about 4 times a week all year long). Scores are factored into the grades. 4th through 8th are tested on add/sub/mult/div and are required to do 100 problems in 3 minutes in order to "pass" that timed test. 3rd does add/sub/mult and must also do 100 in 3 minutes (I think that requirement comes only by the end of the year though). 2nd does all add/sub (sums to 18) and 1st does add/sub for sums to 10, and they also have to do 100 in 3 minutes (only by the end of the year). I was amazed that the 1st/2nd had (almost) the same requirements as all other students - but the really amazing thing is that a lot of them are doing it!
Now, what I'd like to know is how to get my lazy 5th graders to do the same thing (pass with 100/3 mins)!!! : )
