I have observed teachers who really challenge their students to achieve higher order thinking These teachers take their students as early as the Second Grade and teach them how to add, subtract, multiply and divide using only their bran. We call this Mental Math. When I observed a Second Grade Class that had their students mentally answering math computation questions, I put my own son in that class. Shortly after being enrolled, He, too, learned how to do Mental Math. From that point on, math was my son's best subject. Teachers can really make a difference and parents can help affect change.

Children naturally love counting and doing puzzles, but for some reason, when you call it "math", all of the interest flies out the window! So how can you cater to this natural love of 'math' and keep it fun and interesting enough to keep children's interest?!
