Is your child learning to write, or having trouble with penmanship? If so, get a grip! Now, don't be offended...I meant it literally. Getting a rubbery pencil grip (like the one shown below) can really help your child learn the proper finger positioning for writing.
Most kindergarten teachers take the time to correct hand positions, though with the rigors of today's state standards and all they have to accomplish, many teachers lack the time needed to correctly teach this skill. As a result, some children need more time to perfect writing. Now that it is summer you have the chance to get your child's penmanship up to speed. So go get a rubberized grip and practice, practice, practice!
