The latest Miss Mingo story celebrates that school milestone, the 100 Days. Miss Mingo’s kindergarten classroom is excited: “One hundred is a big number, so we will celebrate BIG!” Miss Mingo tells her class, and invites the class to share their 100th Day projects, and each of the students show off their projects: 100 shells, a 100-pound baby sibling (it’s a hippo!), 100 teddy bears, even 100 footprints from five different classmates! Loaded with interesting factoids throughout the story, Miss Mingo and the 100th Day of School has great ideas for 100th Day celebrations, many of which will likely take place over Zoom, Google Classroom, or other video chat. My favorite? Making a silly face for 100 seconds! Watercolor and ink illustrations show expressive, happy animal classmates and their exuberant teacher showing off their talented projects. A good book to have ready for 100th Day storytimes.
