What do you do when you plan your birthday party? Do you order a big cake and have goodie bags for your friends? This engaging e-book prompts students to determine greater than, less than, or equal to quantities by looking at the number of friends invited versus the number of cupcakes, chairs, and party favors available at the party. Early readers will not only learn the importance of quantities, but each engaging photograph allows students to use their oral language skills to collaborate together to create a story about the birthday party in the e-book.
