For example, all children should learn their multiplication tables by the third grade. They should be able to repeat them, verbally, without using a calculator. Children in elementary school who rely on the calculator for the answers are creating math deficiencies, which could have a negative impact on their math development.
Elementary teachers and parents play the biggest role in a child's mathematical development, especially from Kindergarten through Fourth Grade. Time spent in school learning math or not learning math can never be replaced. Parents should make sure the elementary math teacher is knowledgeable and is a good teacher.
Another recommendation for parents is to not allow children to utilize calculators at an early age. Children need to first develop their brains to be able to do mathematical computations on their own. Constantly using calculators at a young age can stunt the mathematical growth of children. If children develop math skills by mentally thinking of the answer to simple problems, they will be better prepared for everyday life, such as grocery shopping, balancing a checkbook, to name a few.
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.
