One great way to teach it is by using math worksheets. One could make worksheets that are fun for children to complete. Adding graphics such as fruit and candy and having the children add them up will open their minds to it and have them learning in a fun way. Also, the sense of accomplishment the child has after completing the math worksheet correctly will encourage him to continue learning the subject.
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.
