Title:
Characteristics of Quadrilaterals
Overview/Annotation:
Students will begin unit on quadrilaterals with basic overview of characteristics of parallelograms, rectangles, squares, rhombi, and isosceles and nonisosceles trapezoids. After the word wall is made, the teacher can use interactive websites to reinforce concepts.
Associated Standards and Objectives
Content Standard(s):
MA2015 (912) Geometry 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. [GCO11]
Local/National Standards:
Primary Learning Objective(s):
Students will understand and compare characteristics of quadrilaterals.
Additional Learning Objective(s):
Preparation Information
Total Duration:
31 to 60 Minutes
Materials and Resources:
card stock strips or sentence strips, markers, wide tape
Technology Resources Needed:
websites, interactive whiteboard and/or projector
Background/Preparation:
The teacher will need sentence strips or card stock with the following printed on them:
one pair of opposite sides congruent
2 pair of opposite sides parallel
exactly one pair of opposite sides parallel
2 pair of opposite angles congruent
consecutive angles supplementary
2 pair of congruent base angles
4 right angles
diagonals bisect opposite angles
diagonals are perpendicular
diagonals congruent
diagonals bisect each other
4 conguent sides
2 pair of opposite sides congruent
Also the students will need 10 cards with "square" printed on them, 7 cards with "rectangle" printed on them, 8 cards with rhombus printed on them, 5 cards with "isosceles trapezoid" and 1 card with "nonisosceles trapezoid", 5 cards with "parallelogram."
Procedures/Activities:
Students will be divided into 5 groups. Each group will be assigned a quadrilateral (parallelogram, rectangle, square, rhombus, or trapezoid(isosceles and nonisosceles). Characteristics should be placed as a large table on word wall. The characteristics are as follows: one pair of opposite sides congruent, 2 pair of opposite sides parallel, exactly one pair of opposite sides parallel, 2 pair of opposite angles congruent, consecutive angles supplementary, 2 pair of congruent base angles, 4 right angles, diagonals bisect opposite angles, diagonals are perpendicular, diagonals congruent, diagonals bisect each other, 4 conguent sides, and 2 pair of opposite sides congruent.
Students will research quadrilateral that is given to their group and place the cards with the name of their shape under each category.
After word wall is complete, students can present their quadrilateral and discuss its characteristics.
The teacher can reinforce discussion with websites. QUADRILATERALS I AND QUADRILATERALS II .
