Students' novel strategies are a valuable resource for mathematical sense making in the classroom. Deliberate exploration of different strategies can support and extend students' mathematical understandings. 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.
