Preparing for New Learning Experiences Without Spending Like Crazy!

In order to get ready for the purchasing of material I write a list of the topics the girls desire to learn and the things I believe are a must to learn.  After writing my list, I list the potential resources I will use to teach the girls the topic. By the time I get to the ordering stage many items have been removed simply because we don't need them.  I appreciate being able to sit with my list before ordering because it keeps me from spending frivolously.
