New York State Next Generation Mathematics Learning Standards

Teacher's field guide

What Students Need to Do: Students identify every quadrilateral with two pairs of parallel sides as a parallelogram. They include rectangles and squares instead of treating a slanted appearance as required.
What Mastery Looks Like: A student marks both pairs of opposite sides on a quadrilateral and names it a parallelogram. The student correctly explains that a rectangle and a square also meet this definition.
Common Misconceptions: Students may name only slanted examples as parallelograms or exclude squares and rectangles. They may check one pair of parallel sides instead of confirming two pairs.
How to Assess It: Show a square, rectangle, slanted parallelogram, and a quadrilateral with only one parallel pair. Ask students to circle every parallelogram and justify each choice.

Lesson moves

Build quadrilaterals with craft sticks, mark parallel side pairs, and sort every figure that has two pairs.
Ask students why a square belongs in the parallelogram group even though it has extra properties.
Play always-sometimes-never with statements about parallelograms, rectangles, squares, and parallel sides.
Find parallelograms in floor tiles, frames, and sign designs, then mark both parallel side pairs.
