1. Welcome to Geometer’s Sketchpad Please place a sticker on the graph… I’d greatly appreciate a helpful, quick glance of our experience in the room. Once you find a seat find the Perpendicular Bisector Entry task on Swift.

2. Learning Targets: Points, lines, segments, rays, circles, text, construction, measuring, transformations, document options, graphing, tables, calculator Become familiar with using GSP: Complete at least one lab Decide upon at least one new way you can use GSP in your mathematics classroom starting in the fall Success Criteria: Identify ways to use GSP as a powerful teaching and learning tool: SMPs,CEL-5D, T.I.M.

3. Agenda Introduction Activity #1 3 levels of options (Beginner, Intermediate, and Advanced) Activity #2 How does GSP support CCSS? Activity #3 Algebra Examples

4. Possible uses in Classroom Presentation tool (Triangle Areas) Entry Task (Perpendicular Bisector) Student lab/discovery learning (Triangle Sum Lab) Assessment/evidence of student learning (Rhombus Proof Project)

5. Pedagogy in the Geometry Classroom Van Hieles’ levels of geometric thinking: Visualization Analysis Abstraction Formal deduction Rigor Sketchpad supports student learning at all levels Standards for Mathematical Practice: Standards 4-8 can be significantly addressed with GSP

6. Activity #1: Try Something New Happy Halloween (Beginner) Triangle Angle Sum Lab (Intermediate) These are all found on the Edge link Pythagorean Triples Lab or Rhombus Proof Project (Advanced)

7. Activity #2: Trig Lab Partially pre-made student sketch These are all found on the Edge link Level of questions aligned with CCSS Mathematical Practices Lab critical piece of conceptual understanding for students

8. Activity #3: Algebra Labs Slope of a Line Slope Game These are all found on the Edge link Quadratic Activity Adding and Subtracting Integers Continue completing your 1 st lab then explore some of these tasks:

9. Thank You! Please answer the following two questions as your exit slip in an email to me. I would really appreciate your feedback and hope to be able to support you in your work in the coming school year. Marcie.Baril@kent.k12.wa.us Explain one thing that you… 1)…plan to use GSP for in the coming school year. 2)…found useful or interesting in today’s training. 3)…are still wondering about as you plan to use this teaching and learning tool.
