Query: Great book for all ages!

I am a grandmother who wants to teach German to my grandchildren. This is the best language series I have seen. It helps me review my vocabulary and with young children, it has the pictures to go with the words. Pronunciation is listed in the back for the beginners of German.We have this series in French, German and Polish. Highly recommend for everyone who wants help with vocabulary in the language. You have to begin somewhere!
