The lesson also helps children learn about remainders and how to record them and see how division and fractions are connected. After hearing the story, students retell it with division sentences and draw pictures to show their understanding of the notation. Also, each child invents a sharing problem and writes a oneeven sequel to the story. Math Focus Points
