The Canvas Commons allows search by grade level, but doesn't exclude by grade level. A teacher searching for a first grade resources gets search results returned for All Grades, K-5, 1st grade. There needs to be a way for the searcher to exclude resources labeled by wider grade bands so they can just return search results that are grade specific. When sharing resources checkboxes need to be for individual grades and not for grade bands so that the contributor must think about how their resources applies to each grade level. A filter should be added so that results are returned only for grades selected and can exclude other grades. As Canvas becomes more widely used by teachers of younger students, those teachers should be able to search for resources without returning Undergraduate results that are labeled for "All Grades."
