Grouchy Dog, LLC is a small, woman-owned business created by an educator to make learning fun for all children. Grouchy Dog, LLC develops games that help children learn common core standards of learning while having fun doing it. It provides fun for the whole family and can also be used in the classroom. Grouchy Dog, LLC is excited to introduce its Rainbow Math system into the market in the Fall 2012. The Rainbow Math system is a series of four bright, fun and exciting games that engage children, parents and teachers with its flexible play and entertaining characters - Tommy the tricky leprechaun and Charlie the spunky bunny. Children can mix and match the cubes for endless hours of fun and learning! Each game in the Rainbow Math series introduces and reinforces common core standards of learning from pre-K through 4th grade, which are explained in each set of rules. It also challenges children to think more critically. There are a few twists and turns as the children advance along the boards toward Tommy's Pot-of-Gold and other treasures, so they have to stay on their toes at all times! A quick note from Margaret, the owner of Grouchy Dog, LLC: Why the name Grouchy Dog? When my students began grumbling during academic time, I used to say, "Stop being such a grouchy dog. Learning is fun!" From that I developed my company motto, "Don't let your child be a grouchy dog... make learning fun!" For more information about Grouchy Dog, LLC, visit www.grouchydog.com.
