Through exploration students will understand the characteristics quadrilateral.
Quadrilaterals for sorting (see attached handout)
Quadrilaterals are closed, four-sided figures. The quadrilateral family consists of regular figures such as the trapezoid, square, rectangle, rhombus, kite, and parallelogram. This group includes isosceles and right angle trapezoids, as well as concave and convex kites. The second group consists of irregular quadrilaterals, which have endless possibilities.
3. Reason mathematically.
6. Represent mathematical situations.
Invitation to Learn
What do all quadrilaterals have in common?
Instructional Procedures
Lesson 1
Lesson 2
Curriculum Integration
Math/Science--Look at different crystal formations to see their similarities
to quadrilaterals.
Possible Extensions/Adaptations/Integration
The purpose of this activity is to enhance sorting and classifying skills, in
addition to adding clarity to the concept of quadrilaterals. Sorting and classifying
skills are necessary when students are classifying animals, kinds of rocks,
types of soil, etc.
Homework & Family Connections
Have students look for quadrilaterals outside the classroom, making a list of
the different quadrilaterals they can find around the house. Which of the quadrilaterals
is the most often used in building? Why?
Give a collection of shapes to students to sort and label them for a performance assessment.
Give students an assortment of polygons and have them sort into groups. Students who correctly identify quadrilaterals would score assessment points.
