Teaching the subject to an older child may be a bit more difficult. There are many math problems out there that can be used to bring it down to their level. Using this subject in an everyday situation is a one idea. For example, tell a story that involves that child. If he goes to the store and buys a gallon of milk with a five dollar bill and the milk is only three dollars, how much money will he have left? Using word problems will help the child understand it more.
Be positive about math _ Our kids like to imitate us; if we send a negative message to them about our own experiences they may simply accept it and believe their own experiences will be the same. So do not groan about how much you hated math in school and definitely do not make flippant comments like you were lucky you learned to count as that is all that you need in life.
