While I am definitely no expert on Math Monkey I know a few basics about their overall curriculum that may be useful to you. Math Monkey is a legally recognized franchise in all 50 states of the US and essentially is an alternative teaching method and viable supplemental education focusing on math skills.
Math Monkey primarily uses the "Vedic" system of math. This is rooted in Indian arithmetic and is a way of performing calculations mentally, without the use of paper or calculators with an emphasis on fun games and activities to engage children.
Math Monkey Mission Statement - Math Monkey Knowledge Centers are a revolutionary new supplemental education service that helps kids to excel by teaching them math in a fun and challenging environment. There are two kinds of kids in the world. Kids who LOVE math, and kids who WILL LOVE math. Math Monkey takes the mystery out of math to turn your little monkey into a big thinker.
