The 512 Ants on Sullivan Street

My son and daughter - aged 5 and 7 love this beautiful little book. The concept of continuous doubling of the number of ants that keep returning to the nest intrigues them. Although the book stops at 512, my children insisted that we keep doubling the number "up to infinity". Well, we kept on doubling until we ran out of paper!! The illustrations are wonderful, complementing this terrific children's treasure.

my four- and five-year old children love this book. it's one they request over and over again when it's story-time at home after dinner or at bed time. they love the little ants who invade the neighborhood picnic and discover a treasure trove of treats that they eventually haul little bits back to their labarynthian home. each time they make the trip they bring more ants, each time doubling their number. my kids very painlessly learned their first multiplication lesson - doubling the number each time. a very cleverly conceived, thoroughly enjoyable book.

This charming, beautifully written and illustrated story helps young children understand the concept of "doubling" numbers. Each time the ants revisit the picnic, they bring more ant friends(in fact, exactly twice as many) to help haul the goodies back to their ant home. The simplicity of the story and each successive illustration with the ever increasing ant army subtly teaches the "doubling" concept. This is a must for any home library.

Engaging rhymes and recurring numberical refrain made this book a favorite of my 3 year old. Fun to read and replete with follow-on exercises building on the concept of "doubling". Highly recommended.
