Bought this book for my 4th grader to work on crititcal and logical thinking. She absolutely loves it. We work on it 2 times a week and she begs to do it every day. Great book! Will definitely be buying all the other levels in the future.
My 9-year-old daughter enjoyed this book. We worked one page a day and she looked forward to doing it every day. I highly recommend these exercises and I have already purchased the next book in the series for my daughter to work on next.
