“This book has been great for keeping my daughter’s mind active this summer. About halfway through the book, however, it switches to fifth grade problems. Some of these she has been able to do, but some of it was not taught in the fourth grade. We just skipped those and moved on. I walked her through some of the word problems because she struggled with these in 4th grade. I’m hoping that the one on one practice helps her be more successful in the upcoming year.”
