Some young children believe that they are loved only when they achieve.
Kindergarten should not be first grade moved down a year. It should be, and in the best programs it is, a time for getting children excited about learning. Your child will be exposed in many different ways to numbers and language. The worksheets that many adults remember are not good for early learners. Children often complete them but do not understand their answers.
