You can take the fear out of math by making sure it is just a part of everyday life at home. By engaging your child in everyday activities that are fun, you might be laying a foundation for a future in math or science. At the very least, you will be giving them a confidence that will make their way through school a little easier. Math does not need to be taught as a lesson. It can be discovered in storybooks or explored at the kitchen table. Preschoolers shouldn't be doing drills or being quizzed, they should just be experiencing an introduction to numbers and patterns found in familiar objects and activities.
