The assignment was to present on a family holiday tradition. On Christmas Day it is her job (and honor) to distribute gifts, an occupation Ken calls the "elf." Care is taken not only to deliver presents to open laps, but to allow for time for appreciation, and make best efforts to distribute evenly, so that any one person doesn't feel ungifted. She does these things well.
For her presentation, she took her research further than her father's tradition, and cited internet articles that discussed mythical elves in various countries and the comparison of their work to her own. Drawing on those fairy tales, she assembled illustrative costumes and created ornamentation to accompany the monologue she'd put on index cards.
I find this quite impressive work for an 8-year-old. What I find most impressive is that she recognizes this as a family tradition and that she is honored to perform as her father and his siblings did when they were children. It's a tradition well worth maintaining and I appreciate her appreciation of it.
