Standards Addressed:
MSGE.9-12.G.CO.11. Prove theorems about parallelograms. Theorems include: opposite sides are congruent, opposite angles are congruent, the diagonals of a parallelogram bisect each other, and conversely, rectangles are parallelograms with congruent diagonals.

Learning Targets /Success Criteria:
--I can identify the properties of parallelograms.
--I can use the properties of parallelograms to find missing angles or side lengths.


Introduction/Connection (Bellringer): Students will classify lines as parallel/perpendicular or neither to given lines.

Direct Instruction/Guided Practice:
--review bellringer
--complete Quadrilateral foldable on Parallelograms (attached below)
--guided practice on Parallelogram properties (attached below)

Independent Practice/Collaboration/Differentiation:
--Differentiation: Graphic organizers, discovery activity, one-on-one assistance for students needing help, provide more rigor for accelerated learners.
--Students will work in pairs or with teacher in small group to complete parallelograms w/s


Summarizer: teacher will give students various information on a parallelogram and ask students if we can prove its a parallelogram (sample problems from IXL lesson N7)

Resources: DeltaMath or IXL

Assignment: IXLs due date TBA:
--N6 Properties of Parallelograms (shortcut LLK)
--N7 Proving a quadrilateral is a parallelogram (shortcut H89)
