Margot decided to invite ten of her friends over for her birthday party. We find out that all of her friends prefer different things, especially one little boy who never picks the same thing as anyone else. Margot explains what kinds of food her guests like to eat, what they like to sing, their mode of transportation to and from her house, their outfits, times of arrival, and what games they prefer to play. Each category adds up to ten, so it might be a good book to show students that different numbers add up to make the number ten.
