  1. Addition and Subtraction Scaffolding Instruction

  2. Big Picture of Session • TEKS Focus: Addition and Subtraction • Instructional Focus: Scaffolding • Scaffolding Focus: Effective use of graphic organizers and representational tools to develop, bridge, and build conceptual understanding

  3. TEKS Focus

  4. TEKS Focus

  5. Instructional Focus: Scaffolding Scaffolding

  6. According to Lev Vygotsky . . . “The zone of proximal development is the distance between the actual developmental level as determined by independent problem solving and the level of potential development as determined through problem solving under adult guidance or in collaboration with more capable peers.” L.S. Vygotsky, (1978)

  7. Scaffolding Unknown “Through scaffolding, the teacher was able to build bridges from the unknown and not understood to the known and understood.” Henderson, Many, Wellborn, and Ward. (2002, Summer). Reading Research and Instruction, 41(4), p. 310. Known

  8. Video Reflection • How does the instructor scaffold Tomika’s learning? [Tomika Video]

  9. Reading Academies

  10. First Turn/Last Turn • Read individually. Highlight 2-3 items. • In turn, share one of your items but do not comment on it. • Group members comment in round-robin fashion* – about the item (without cross-talk). • The initial person who named the item then shares his or her thinking about the item and takes the last turn, making the final comments. • Repeat the pattern around the table. *Round-robin is a highly structured participation strategy. Group members speak in turns, moving around the table in one direction.

  11. What Is Scaffolding in Mathematics Instruction? What is Scaffolding in Mathematics Instruction?

  12. Scaffolding Focus Bridging conceptual understanding using: • Graphic organizers • Representational Tools

  13. Video Reflection What are some examples of videos shown yesterday that use a graphic organizer to enhance understanding?

  14. Scaffolding Instruction Through Questioning “Teachers can use questions as a kind of scaffolding to help students reach higher levels of thinking and learning. . . In the asking of questions, teachers are thinking actively and helping students be active thinkers” (Walsh and Sattes, 2005, p 23).
