Grouchy Dog®, LLC is excited to introduce its Rainbow Math® series!  Whether you are having a family game night at home, you home school your children, or teach in the classroom, Rainbow Math® will make learning math fun for everyone!

Grouchy Dog® is a small, woman-owned company created by an educator to help teachers and parents by developing educational games that engage and entertain all who play.

It is hard to believe that it all began in 1993 with the board below made out of construction paper and markers!  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.

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

"A student gave me a Rainbow Math 3: Pirate Adventure Game as a gift for our math enrichment program. I wanted to share that as a parent and a teacher, I have been unable to find a game that is able to reach such a diverse group of learners. That is until I used your game with my students.
   I am planning for next year and the ideas for using this resource, at differentiated levels, with all types of learners in grades K-5 are endless. Your game will provide my students with a fun learning experience that will boost confidence and strengthen concepts and skills in math.
   I am so pleased that my student shared your game with me. I look forward to using it next year.
   Thank you for creating and marketing such a valuable math learning resource!"

Ms. Fairchild ~ Math Intervention Coach

   "If you are a mom, an elementary teacher, or a parent who home schools preschool or elementary age children, you've got to check this out!
   I am definitely buying the 2nd one in the series (addition & subtraction) so I can do some hands on practice with my son this summer.
   This is a great interactive game for all children, but especially for my son who doesn't do well with sitting down and completing pencil & paper exercises."

Suzanne ~ a Mom

LOVED the games so much that I gave one to my favorite kindergarten ABA teacher and will be buying a new one soon!
Lisa ~ Speech Pathologist

"My son loves the game!! He 'played' it by himself when we first got home, and then we played together. He said it's awesome! The colors are vivid and there are so many variations to the game!

Karla ~ 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 6

   "My son and I love playing Rainbow Math 3, Pirate Adventure, together.  He enjoys rolling the dice and solving a different math problem every time. 
I appreciate that the game has the flexibility to meet him at his level - now addition and subtraction - but also to challenge him further.  We did a multiplication "bonus round" after he won the addition and subtraction round. 
Rainbow Math allows my son to feel successful and excited about math.  And it gives us an opportunity to spend time together.  What could be better?"

Michele P. ~ A Mom

"We love your Math game!  Thank you for helping us learn math.  We like the rainbow colors and what you have written inside the boxes.  They keep the game exciting every day!"

"I am a special education teacher and love this concept.  I see this working in school, home, daycare and in the homeschooling environment."

Susan ~ Special Education Teacher

"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."
