Measure the angles and sides of parallelograms to establish facts about parallelograms.
Clarifications:
Essential Understandings
Concrete:
- Draw or construct a parallelogram.
- Measure the angles and sides of a parallelogram to show congruence.
- Draw diagonals on a parallelogram.
- Use paper folding to determine congruent angles and sides, diagonals, medians, and midpoints of a parallelogram.
- Identify characteristics of parallelograms.
- Understand the following concepts and vocabulary: acute, obtuse, right, parallelogram, rectangle, rhombus, square, base angles, midpoints, median, congruent, bisect, diagonals.
- Label and describe congruent parts of parallelograms.
- Construct diagonals and medians of parallelograms.
- Use descriptions of characteristics of figures to identify and classify figures (i.e., parallelograms with congruent diagonals are rectangles).

Cluster:
Prove geometric theorems. (Geometry - Major Cluster) :
Clusters should not be sorted from Major to Supporting and then taught in that order. To do so would strip the coherence of the mathematical ideas and miss the opportunity to enhance the major work of the grade with the supporting clusters.
