All students love proofs!! Well that might not be the case, but this product will allow you to differentiate. My favorite way to implement this activity is using proof placemats. To prep for this I print the statements and reasons on card stock, cut them out, then during class students will arrange them on a blank proof sheet paper. The proofs you select to use can also be copied into a proof booklet. Each proof comes with an answer key, a blank sheet, and a complete the reasons option.
If your curriculum includes the property: Each diagonal of a parallelogram divides it into two congruent triangles, then proof 1.5 and 2.5 will save your students some time and work. However if this is not a property that your students use, proof 1 and 2 use congruent triangles to prove these properties of parallelograms.
Here are the properties that this product will help your students prove:
Each diagonal of a parallelogram divides it into two congruent triangles.
In a parallelogram, opposite sides are congruent.
In a parallelogram, opposite angles are congruent.
In a parallelogram, diagonals bisect each other.
Do you like to save money?? The Parallelogram Proof Bundle includes this product and Part 2. Parallelogram Proofs Part 2 extends to specific properties of rhombus, rectangle and square and is over 80 pages of Parallelogram PROOFS!!
