Students study credit and interest in a novel and consumer math activity. In this credit instructional activity, students read the book Bingo Brown and the Language of Love. Students discuss the book and the ideas of credit, interest, and loans. Students complete a home activity about the services they pay for in their home. Students then work in groups to create a collage of images that people buy with credit. Students write a letter to Bingo about credit and a school announcement about credit.
