Kids in second grade are learning their math facts to 20 and addition is much easier for them to understand than subtraction! Why is it more difficult? "...because it involves a negative action that is a secondary construction of addition." (Jean Piaget, 1980) He also states that "children initially think and perceive in only positive terms. When they see a red ball, they first think of it only as red and a ball. A considerable time later they are able to think of the same ball as not blue, not green, not a cup" and so on.
To help your kids practice subtraction at home, I've added a new link on our blog under our Week at a Glance. The Fruit Shoot Game has many different levels and kids can do it in a relaxed way or a timed way. I would recommend the relaxed way because this will help them actually begin to really learn the facts. Most of our practice is NOT timed so kids can practice and learn without that pressure. Try level 2 because this is our focus. If your child has mastered these facts please let him/her play other games on the site!
As I find other good links, I'll add them to the list. If you find any, please let us know!
Happy Subtracting!
