Miss Bindergarten Celebrates the 100th Day of Kindergarten . Joseph Slate
To celebrate one hundred days in Miss Bindergarten's kindergarten class, all her students bring one hundred of something to school, including a one hundred-year-old relative, one hundred candy hearts, and one hundred polka dots. The clever text moves briskly in rhyme (with alphabetical order tucked in); the celebration is joyous; counting and early math concepts abound; and everyone's one-hundred-full efforts are recapped in a notebook Miss Bindergarten puts together on the last pages. Children will surely revel in the pictures, which are filled with the love that Miss Bindergarten pours into her classroom and students, and the pride and pleasure that they take in their own work and in one another. This is a book that will both satisfy and motivate on many levels.
