If your child is used to doing a worksheet or two, they will be able to do this quite easily, and will understand that they need to complete the task before they can move on to the next activity. Worksheets also help your child to learn how to follow instructions, and teach them about following rules.
Since 3rd grade math relies on the concepts that were learned during kindergarten, first and second grades, don't be afraid to start your child at a lower level.
Kindergarten worksheets are often of much value in helping kindergarten children learn and re-inforce basic concepts in an interesting way. Small children usually like to do things rather than just read or listen. They also get bored rather easily. Therefore giving them well-designed, illustrated worksheets to do makes it easier and more fun for them to learn. Completing a worksheet also gives a child a great sense of fulfillment. In fact, not just for kindergarten, but even for older learners worksheets can form a valuable part of the learning process.
Teaching reading and other language arts skills to preschool learners relies heavily on a concept known as modeling. Modeling merely means exposing young children to the types of behaviors and habits we want them to learn. Many parents and homeschooling educators employ this kind of instruction naturally, without giving it much thought.
