(Citation 2014) investigated the nature of opportunities to engage in reasoning-and-proving in elementary mathematics textbooks to determine what opportunities exist in student text materials for students to engage in reasoning-and-proving, such as making claims, justifying claims, evaluating claims and what aspects of reasoning-and-proving … Webb23 sep. 2024 · A proposition is a claim that needs to either be proven or disproven. There are three main kinds of proposition: Theorem: These are strong propositions. Lemma: These are subsidiary propositions of a theorem, used to proof the theorem. Corollary: These are propositions that follow almost immediately from a theorem.
