No matter what materials you choose, it is most important that you supervise your child constantly so that mistakes get caught rather than practiced. I learned this particular lesson the hard way. When my daughter was young, she did something that needed "attention." I no longer remember what it was that she did, but I told her to write the sentence "I will not disobey my parents again" 50 times. I should have known better, but I didn't check on her at the beginning and then I got busy. So, sometime later, she brought me 50 sentences of "I will not disobey my parents agen." She had just practiced misspelling "again" as "agen" __ 50 times! I'm not certain that we ever really got that fixed. This issue of NOT practicing mistakes is extremely important. Parents shouldn't give worksheets as busy work and teachers should only use them if you are going to have a non_math teacher substitute. White boards with supervision are always a better way to practice skills. If you need some time to do chores, your child will get much more benefit by helping you with the chores. And maybe you can work in a little discussion of numbers or counting while you do chores together.
The same is true for mastery of working with fractions. _ So, in general, kids who don't learn their multiplication tables and arithmetic with fractions usually don't do well in math. It's been proven that success in science depends to a great extent on success in math. So, these same kids usually don't do well with science, either. In other words, they're locked out of most of the growth that our economy is going to experience in the future. According to the federal government, eight out of ten jobs in the next twenty years are going to be computer related. If you want your child to have access to the major portion of jobs in the future, your child must master math. It's that simple. The Solution...or at least part of it _ Teachers are actually doing their best to educate children. The problems with education aren't so much on the level of teachers as with the institution as a whole. It's kind of like the state of communications in our country before the deregulation of the telephone companies. Before deregulation, one and only one advancement__the touch tone phone. After deregulation, well you have cell phones, the Internet, instant messaging, you name it! _ What dedicated teachers and parents need to do is to supplement public school instruction with strategies that work, that have always worked, to get kids to really master the fundamental skills of elementary math.
