None of this is true, of course. So, first you need to bite your tongue. Secondly, get your child interested in math from an early age. Math does not have to be about columns and columns of figures, and the sooner you can introduce your child to math in a fun way the better. Mathematics worksheets can help you do this, with pages of fun exercises that will teach your child the basic principles they need. This helps you, as you don't have to write out pages of math exercises and try to make them interesting _ it also helps your child. A good set of kids math worksheets will present math in an exciting way, incorporating lessons of quantity, counting and writing numbers in a way that children understand and relate to. Mathematics worksheets should use different methods to teach your child the principles of addition and subtraction to make sure they understand the concept, not just learn the answers by rote. A decent set of worksheets will use step_by_step methods to help your child progress from the first steps in number recognition and counting, to more complicated sums and word problems.
I will admit that there is one type of worksheet that I used in the past and found relatively beneficial, although it had a different kind of flaw. For my Basic Math, Pre_Algebra, and Algebra classes, I had several books of "self_checking" worksheets. These worksheets had puns or puzzle questions at the top, and as the students worked the problems they were given some kind of code for choosing a letter to match that answer. If they worked the problems correctly, the letters eventually answered the pun or riddle. Students enjoyed these worksheets, but there are a couple problem areas even with these worksheets. Some students would get the answer to the riddle early and then work backward from letter to problem answer, so they weren't learning or practicing anything.
