We're doing Expos to review our summer assignments before we jump into new content.

Monday, 9/12 - This was Eid al-Adha, and no public schools were in session.

Tuesday, 9/13 - Today we started work on our Expo presentations. Here are the slides from class, where you can find your Expo groups and the procedure for these Expos.

  • Discipuli will receive a grade for completion of their summer assignment
  • Discipuli will prepare and present Expo presentations, assessed by the TBLS Expo Rubric for a 100 point process category grade
  • Presentations should remain under 7 minutes and will be done with the aid of a document camera
  • Presentations should follow the steps of the "How to Solve It" framework (understand the problem, devise a plan, carry out the plan, review/extend - see below) and address each of the substeps
  • Talk time should be balanced among group members (probably means don't give one part of the framework to each person)
  • Questions on the exam will be very similar to those found in Expo presentations (some maybe exactly the same)
  • Schedule: Prep on Tuesday and Wednesday; Presentations on Thursday and Friday (and maybe -Monday) and Exam on Monday.

Below is the "How to Solve It" framework we used in class, which will be helpful for you to think about throughout your IB math career.

  1. Understand the Problem
    • What is the given information?
    • What are you asked to find or show?
    • What are some keywords? Define them.
  2. Devise a Plan
    • How are the given info and unknown connected?
    • Which properties or formulas could be useful?
    • What strategies can you use to organize the information? e.g. graphs, diagrams, tables, etc.
  3. Carry out the Plan
    • Show all steps of the solution
    • Keep the information organized
    • Have a justification for your steps
  4. Review/Extend
    • How can you check your result?
    • What are possible misconceptions? Why?
    • Are there other ways to derive the same result?

Wednesday, 9/14 and Thursday, 9/15 - we continued working on the Expos in our groups.

Friday, 9/16 and Monday, 9/19 - we present our Expos.

Tuesday, 9/20 - we'll present any leftover Expos and also take an exam with questions directly inspired by Expo problems.
