This lesson integrates reading, writing, viewing, and visually representing mathematical ideas. Using two math-related books, the lesson gives student a real-world context to practice grouping objects and skip counting. The texts selected for this lesson follow predictable formats that support emerging readers, and students can use these structures as frames for their own writing. After reading each of the books, students explore their school and home environments to find and represent their own examples of sets. In the culminating activity, students create a collaborative class book. Students identify and represent sets of objects with numbers, words, and pictures on pages they contribute to the class book.
