In order for students to understand proofs, past research shows that it helps them to name where the reason is pulling from. The only reasons that don't need to "call upon" earlier reasons are the givens. Therefore, when I have them name "Reflexive Property" as one of the reasons, they must also name "picture." Blanks are provided for these.
Practice problems are provided on page #2. Amount of steps are provided, but the proofs become less scaffolded as the worksheet goes on.
