I thought you would have been answered by now. I've read about, but never seen, a set of workbooks Called gifted and talented reading workbook grade 2, etc., at Barnes and Nobles. The deal with these books is that a child who is an advanced reader can read the passage then the questions have a multiple choice that they only have to be able to mark the right one.
Otoh, I'm just asking my son to tell me the answers on the math workbooks so I can reuse them for my daughter. Also wanted to tell you when we started the fine motor skills there were a lot of "draw a line between the items that go togeather from each row.". I would ask him to point to the matching birds, then I would put a finger on each of his answers and he would draw the line. Rinse, repeat, produce a nice sheet for the fridge.
