IB Math AA SL 1.6 - Deductive Proofs

This IB Math AA SL 1.6 – Deductive Proofs slide deck introduces students to the structure and purpose of mathematical proof, focusing on transforming expressions step-by-step to show statements are always true.

Learners distinguish between equality and identity, then apply proof strategies such as starting from the more complex side and simplifying toward the other. Examples include proving algebraic identities and writing simple number-based proofs (e.g., explaining why even-number squares are divisible by 4). The presentation provides clear tips, templates, and guided practice to help students communicate logical reasoning with clarity—an essential IB skill.
