In order to develop a student that has good math skills, a parent must play a key role in the learning process. In addition to parents, teachers and other family members are very important to a child's mathematical development.
I have observed teachers who really challenge their students to achieve higher order thinking These teachers take their students as early as the Second Grade and teach them how to add, subtract, multiply and divide using only their bran. We call this Mental Math. When I observed a Second Grade Class that had their students mentally answering math computation questions, I put my own son in that class. Shortly after being enrolled, He, too, learned how to do Mental Math. From that point on, math was my son's best subject. Teachers can really make a difference and parents can help affect change.
The addition, subtraction & number counting worksheets are meant for improving & developing the IQ skills of the kids, while English comprehension & grammar worksheets are provided to skill students at constructing error free sentences.
Computer based math practice problems are helpful in training children how to use math skills in real life while still using tried and true methods of testing. As with the old-school techniques, modern math programs also use multiple choice, fill in the blank and true or false questions to quiz students.
