There are several standard exercises which train students to convert percentages, decimals and fractions. Converting percentage to decimals for example is actually as simple as moving the decimal point two places to the left and losing the percent sign "%." Thus 89% is equal to 0ቑ. Expressed in fraction, that would be 89럼. When you drill kids to do this often enough, they learn to do conversion almost instinctively. Ratios and proportions are likewise wonderful math lessons with plenty of interesting practical applications. If three pans of pizza, one kilo of spaghetti, two buckets of chicken can properly feed 20 hungry friends, then how much pizza, spaghetti and chicken does mom need to prepare for birthday party with 30 kids?
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.
