JBDad, if the teacher insists on only add/sub in 1st grade, how about asking if you can send in Singapore Math challenging word problems (CWP) workbooks. There are some nice multi-step word problems that only involve addition/subtraction but on up into the thousands etc. There is also multi/div in there so if DS should happen to the wrong page, ooops. LOL. You could probably go on up to SM CWP 4A/4B which is addition/sub but adults often require algebra to set up - SM teaches bar diagrams so it wouldn't look like algebra to the teacher.
