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.
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.
