A little more clarification...My 7th grader has been a natural speller up until 5th grade. She started struggling more at that point. I feel that she still needs something, but not sure that starting at level 1 would be good. Since I am buying it for my 5th grader I was hoping to use it for both, but is there something else that could be recommended for a 7th grader that has not struggled up until about 5th grade?
