Use minimath debates to allow students to take ownership, support, and critique mathematical ideas to convince peers why they agree or disagree with particular mathematical statements. Postscript items are designed as rich grab-and-go resources that any teacher can quickly incorporate into his or her classroom repertoire with little effort and maximum impact.
