The Learning wheel has many different workbooks and study guides for kids of all ages. Has a broad selection of the popular Barron's Regents Preparation books which cost about six dollars. Science project display boards can also be found here, although not for that cheap. All types of other things that have to do with school can be found here. I recommend going here if your child is struggling in a certain area so you can buy him/her a workbook, I'm sure it will help. I used to buy Regents preparation books here all the time an all my regents grades were in the 90s!
