Thanks for the words of advice regarding written math. My son prefers to do math in his head but when I need a few minutes alone I usually write a bunch of problem on a sheet of paper for him to solve. Not only has this helped him learn what the symbols mean it also helps him with his writing (which still included a backwards number 5).
I am not very familiar with achievement testing. Are there also ceilings on those or do they continue until they find that the child can't figure out more problems.
