Parents can assist with developing a lot of the fundamental skills needed for children to succeed in math when they attend school. Parents can do things that will support the schools and hopefully the schools will do the rest.
The same general idea worked when it came to my son's Lego's! It was a great way to work on patterns and following directions! I would draw a pattern on paper for him to copy and recreate with his Legos. It not only helped with his color recognition, but his problem solving skills, fine motor skills and he didn't even know he was doing math!!
Learning centers provide many opportunities for integrated learning. While playing in an imaginary grocery store, children learn math through the use of numbers and prices, literacy by recognize familiar labels on foods and develop social skills through role play as the shopper, cashier or manager and develop their physical skills by learning how to arrange cans and groceries in make-up shelves.
There was a time that the United States of America had some of the highest mathematic scores in the world for students in grades k through 12. A lot has changes since those days, and in order to help children get back on the path to being good mathematical students parents need to play an important role.
