Sort & Classify Quadrilaterals: Trapezoids & Parallelograms 3.G.1 Day 2

Trapezoids A quadrilateral with at least one pair of parallel sides Parallelograms A trapezoid with 2 pairs of parallel sides Rhomboid A parallelogram without right angles and sides of different lengths Square A parallelogram with all sides the same length & 4 right angles Rectangle A parallelo gram with 4 right angles Rhombus A parallelog ram with all sides the same length Kite A quadrilateral with 2 pairs of ngth sides adjacent to each other Quadrilateral A polygon made of 4 line segments Deltoid A concave kite

Quadrilaterals: A polygon is a 4 sided figure

Task 1: All the quadrilaterals in the circle match my rule. All the quadrilaterals outside the circle do not match my rule. What do you notice? What do you wonder?

Task 1 (cont.): Guess my rule. Video - play at 2:04Video - play at 2:04 Sort the rest of the quadrilateral shape cards using my rule. The rule is: ____________________________________.

Trapezoid A trapezoid is a quadrilateral with at least 1 pair of parallel sides. Find trapezoids in your bag of shapes!!

Task 1 (Independent Practice): 1.Choose the five trapezoids from the set of quadrilaterals shown below. 2.For each trapezoid, highlight in yellow pairs of parallel sides. A. B. C. D. E. F. G. H.

Stand Up, Hands Up, Pair Up When the music starts, move about the room. When the music stops, high-five a partner. Share, listen, and respond. _____ I agree with your answer, because…. _____ I am a little fuzzy about… _____ I disagree with your answer, because….

Stop and Reflect Think-Write-Pair-Share: What have you learned about quadrilaterals and trapezoids so far?

Task 2: Look at the quadrilaterals that were not trapezoids. 1)What are some things that are the same about these shapes? 2)What are some things that are different?

Parallelogram: A trapezoid with 2 pairs of parallel sides 17 Find some parallelograms in your bag!!

Task 3 (Independent Practice): Cut apart the shapes. Place each shape in it’s correct location on the graphic organizer. Trapezoids A quadrilateral with at least one pair of parallel sides Parallelograms A trapezoid with 2 pairs of parallel sides Quadrilateral A polygon made of 4 line segments
