Hi,
My wife is a Montessori pre-K teacher and I make games. I've made a math game to improve the development of number sense for 5 yr and up, and I am trying to find home school teachers who will help me. She has played it in her classroom with much success and delight of the students.
It is called Greater Than Lessons, and it has a big wood die and brightly colored number cards to practice using greater than, less than, and equals symbols.
I am going to be raising money on Kickstarter to get it made. If anybody knows a good resource to help me get the word out, that would be GREAT! This is the link to the game https://www.exitgamesttg.com/
