Yesterday while we were at Home Depot buying the bulbs, we spied some birdfeeders. They were very inexpensive so we snagged two and Voila! instant homeschool project for today.
We got a feed sock like this one http://www.bestnest.com/bestnest/im
Homeschool budgeting just doesn't get any finer than that. For less than ten dollars, we have lessons for the day and enrichment for home and education for the rest of the YEAR.
