Hi Wendy - welcome to the board. I hope you enjoy making your first quilt.
Some blocks I would recommend for your first time are:

http://www.quilterscache.com/N/NinePatchBlock.html

http://www.quilterscache.com/T/TheAttractionBlock.html (this is a bit more challenging - but it is one that seems popular with younger people - I would recommend doing the 8" block)
