Math vocabulary

 

            Parents who use math vocabulary when speaking with their children help them to have a better basis for understanding mathematical concepts. If you know the meaning of these terms, use them and explain them when you use them. If there are some that you don’t know, find out what they mean and make an effort to incorporate them into your speech and activity.

            Helping a child to feel secure in math is easier done when she is younger. It usually doesn’t take too much practice to get children comfortable with many of these concepts. It’s just a matter of introducing a word or phrase, using it, showing the context, and practicing it on a regular basis.
