Query: Fun, easy to learn grammar book. Great!

My kids like all the pop-up which are well done. Our second grade teacher borrowed it...it came back with a few of the pop-ups destroyed but I'm buying a second copy. It is easy to really understand the grammar concepts after going through the book. It was a good way for an adult to learn too--just in case you want to know about prepositions or adverbs or other long forgotten concepts.
