The goal of the Indiana STEM Network (ISTEM) is to help Indiana become a national leader in student academic achievement in STEM disciplines. This section of their well-thought out website provides a wealth of information on excellent lesson plans crafted by their team of experts. Currently the site has over 300 of these plans, organized by intended audience, target grade level, and subject. The Recently Added area is a great place to start and it contains fun explorations, such as Variables Lesson, Bar Graphs: A Statistical Skyline, and I've Seen That Shape Before. Those persons looking for highly recommended resources should look at the Most Recommended resources for items that have received high marks from peer reviewers.
