His class is first introduced in Karen's Candy. The students in Ms. Colman's class volunteer with his class to prepare costumes for the Halloween parade. One of his students is Leah Frenning.
Nancy Dawes is made Mr. Posner's teachers aid for Switch Day in Karen's Tattletale. The class recited a poem about an elephant and a telephone for the school anniversary event. One student could not stop giggling and then the whole class laughed too.
His classroom doesn't have desks, just two long tables. Around the room is blocks, toys, easels, and dolls, as well as books, writing paper and some math games. There's a class pet, two mice named Hunca Munca and Stuart Little.
