Is there a way to search for content by grade level? 

Search is a very powerful feature in Mizzen and it allows you to locate content across a variety of criteria, including grade level, tags, category, publisher, and duration of activity. To use the search feature, go to the Content area of Mizzen, then tap on Search in the lower right corner. Tap clear search, then if you’re searching for content by grade level, simply drag the sliders for the grade range filter to match the range you need, then tap search.
