Classroom materials and tech (checklist)

• OneNote pages set up in advance: “Homework check”, “Letter Combinations”, “Pair Answers”, “Homework answers”.
• Visible timer (projected or phone).
• Sticky notes / index cards for pairs to write one-sentence responses.
• Table camera or phone + tripod if you want to show student work live.
• Calculators, rulers, or other tools for math tasks as needed.
• A simple formative checklist in OneNote to track pair reasoning.

Mini-evaluation rubric for TPS (teacher use)

• Content accuracy (0–2)
• Clarity of explanation (0–2)
• Use of example (0–1)
• Pair interaction (observed: both spoke? Y/N)
  A target pair should score 5/5; use rubrics to guide feedback immediately.

Classroom example scripts (short)

• After homework check: “We’ll connect the combinatorics idea from p.70 to today’s activation. Think: how many permutations for E I T? (60s). Pair: compare lists and record one compact explanation (4 min). Share: I’ll collect three pair explanations and post them on our ‘Letter Combinations’ OneNote page for everyone to copy.”

Concluding and follow-up

• Always end TPS cycles with a concise teacher synthesis (2–3 sentences) linking pair ideas to the model solutions, highlighting concepts like “number of options” and “elementary case”.
• Collect pair work into OneNote “Pair Answers” to document learning and to use as a basis for homework correction or formative assessment.
• Plan to revisit the method at least 4 times (your course guidance): new students and new routines need repeated practice to become efficient and productive.
