Your algebra, geometry, 3-D descriptions are very accurate. DS hasn't done too much of 3-D geometry, but he does have to work hard on problems such as find all sides of a cube if different views of the cube are given. He just does not like those kinds of problems. Lately, he resulted to make a cube, put post-it on the sides to figure out shocked

Dottie, you are amazing. You got the subtest scores based on one PRI score! DS is a happy kid most of the time. I guess I won't worry too much until a problem presents itself.
