Knowing how academic kindergarten is these days would you have done anything differently with your child before they entered kindergarten? Would you have worked at home with them more before they entered? Looking back if you did not send your child to preschool, should you have? If you did send them to preschool, did it better prepare them? Is your local kindergarten more like first grade? What do the children need to know before they enter? What do they expect the kids to know by the end of the K year?
I think that with kindergarten being what it is, kids who don't go to preschool can be at a disadvantage. That's because preschool gives kids practice with focus and social skills that are absolutely essential to kindergarten success. My son has just started kindergarten and I'm amazed at all they're doing already! I did do a lot of the activities on the website with him over the summer and I think it helped get him prepared, without being what he calls "boring" (aka, some workbooks on the market.) Here's the link to the preschool activities, which are almost all written by teachers and are meant to help with kindergarten readiness: http://www.education.com/activity/preschool/
Luckily, they're fun, too ;) Also, we have lots of articles on what happens in kindergarten academically and what kids are expected to know by the end of the year in our Parent's Guide to Kindergarten: http://www.education.com/grade/kindergarten/
Let me know what you think! Hope this was helpful and good luck.
