As a parent I was curious to know what children learn in each grade to help me teach my children at home. I want to focus on helping to get my 3 year old ready for Kindergarten by learning what children typically accomplish in preschool. I found a comprehensive list of what children learn in each grade from Preschool to grade 12 at an About.com Homeschooling page.  It is interesting to learn what my 3 year old knows has well as what my 1 and a half year old know and what I need to work with them on. It is a great guideline to help think up fun educational activities for my girls!
