Who Is Grouchy Dog®?

Grouchy Dog®, LLC is a small, woman-owned company created by an educator and a mom to help teachers and parents teach their children skills that support the common core standards of learning, all while having fun!  Our board games are vibrant and exciting so children are instantly engaged, and with their minds activated and curiosity piqued, they are ready to learn.  So, come on, let's play! 

It all began in 1993 with the board below made out of construction paper and markers - hard to believe how far it has come!  Creating Grouchy Dog®, LLC and developing Rainbow Math® has been quite an adventure - that's for sure! 

Thank you to Tommy, my other students, my co-teacher Mary, and all my friends and family who helped me during the process.  I could not have done this without you!

What People Are Saying About Rainbow Math®:

"My Kids love Rainbow Math 1!  My two girls and I would play together, but now they play together by themselves with their own rules.  It was great to see them put away their iPads and choose to play the game instead.
   It’s fun, educational and easy to look after, which is everything I could ask for in a game.  My daughter loves the game so much that it has a place next to her bed!
   We will definitely be moving on with Rainbow Math 2!"
Kristen ~ a Mom

"When you play Rainbow Math you have the experience of getting better at multiplication, division, addition and subtraction.  It's really fun because the higher numbers will get you to the treasure faster."

Gabe M. ~ 1st Grader, Age 

"Fun.  It helped with math skills quickly and within the space of one game.  Easy to learn and finish.  I liked that different ages could play at the same time."

Mike ~ Dad
