We've read a good number of poems in the Martial class already this semester, and I wanted to think of a way for the students to review them and see patterns among them. So I typed up a bunch of slips: one for each poem we've read, giving the poem's first line and leaving room for a student to write some notes about the poem. Each student then got their own set of slips for all the poems we've read so far and sat quietly, grouping the slips according to similarities of whatever sort they saw among the poems. Then we shared our favorite groupings. I don't think I'm explaining it well here, but I liked it a lot as an activity!
