Number talks are"...classroom conversations around purposefully crafted computation problems . . . that students solve mentally" (Parrish, 2011). Number talks facilitate the development of computational fluency "while thinking and reasoning like mathematicians" (Math Perspectives, 2007). "During number talks, students are asked to communicate their thinking when presenting and justifying solutions . . . which leads to the development of more accurate, efficient, and flexible strategies" (Parrish, 2011).

Special Opportunity!

Visit a Co-Teaching Demonstration Site in Region 4

The Virginia Department of Education has identified 27 co-teaching demonstration sites through the Excellence in Co-Teaching Initiative, including 6 at middle schools and high schools in Region 4. These demonstration sites provide opportunities for co-teaching partners throughout the state to observe inclusive practices in action. The co-teaching teams at the demonstration sites share their co-planning, co-instructing, and co-assessing practices that support successful outcomes for all students.

For more information about the Excellence in Co-Teaching Initiative, or to arrange a visit to one of these model sites, please contact Dr. Lynn Wiley, Director, VDOE TTAC at GMU at or 703.993.4496.
