The only things I could think of to make this book even better would have been to have perforated pages ( I used an exacto-knife to remove each page) and to have tracing numbers in the back too. Overall, extremely happy with the quality and content of this book!
To add: the more practice, the better! So I cut these pages out to slide into clear sheet protectors from the dollar store, and my kids use dry erase markers directly on the sheet protector. It wipes right off and then they can practice again!
