Our chapter has a typical class size of 40 to 50, so this year we did this:
Each big chooses/makes a pair of shoes and wraps it up. The littles come in and unwrap their presents and put the shoes on, then they file into a room. The bigs are against the walls, but there is a curtain held up between them and the littles. The littles find the place to stand by finding the foot with the matching shoe (so she looks around and finds her big's foot sticking out from under the curtain). Once everyone has found the right shoe, the curtains are dropped and viola! It's really cute
