Integrated Math II · Week 33 · Proof, Measurement, and Review
Parallelogram Proofs
Justifying every claim in a proof; integrity in arguments.
- Students will
- Students use properties of parallelograms to solve for unknowns and justify each claim with a reason.
- SEL skill
- Check that every claim has a reason and say so honestly to a partner
- What it looks like
- Students practice honest reasoning by checking that every claim has support.
- Content focus
- Proving theorems about parallelograms
- Format
- Partner exchange
