## #1899. Geometry Fun

Mathematics, level: Elementary
Posted Wed Aug 9 07:13:33 PDT 2000 by Jaime Hess (bgfg@grove.Iup.edu).
Indiana University Of Pa, Indiana, PA
Materials Required: Power point
Activity Time: 40 minutes
Concepts Taught: Shapes and basic geometric concepts

Lesson Rationale
Students will learn the basic definitions of a quadrilaterial, parallelogram, rectangle and square and explain
the relationship/classification process between them. This is an important skill because the learners will be
taking a geometry class the following year and need this background information to succeed.

Lesson Objective:
After a powerpoint lecture and a class activity on relationships within quadrilaterials, parallelograms,
rectangles and squares, Students in the forth grade will be able to draw the correlation between
quadrilaterals, parallelograms, rectangles and squares with 100% accuracy.

Lesson Activities
Lesson Initiative:
Select three students. Give each student one of the following words: cat, mammal, animal. Ask the
students what the most general of the words is (animal). Have the student with that word stand in the
front of the class. Then ask the students what the next general word is (mammal) and have that student
stand beside the first. Ask the students what the most specific word is (cat) and have that person stand
beside the other three. Explain that as we know a cat is a type of mammal which is a type of animal.
Tell the students that what they will be learning that day about shapes is the same idea.

Instructional Process
Materials:
words cards (cat, mammal, animal, rectangle, square, parallelogram, quadrilateral).
Power point presentation

Process
*Using Power Point presentation (or by using actual cut out/block form shapes) show the
quadrilateral and give the definition (4 sided shape).
*Have a student come to the front of the class and hold the word and an example of a
*Do the same for the parallelogram.
*When the second student is at the front of the room with the parallelogram ask the
students if a parallelogram is a quadrilateral and why.
*If the students have trouble tell them to remember the definitions and the cat/mammal/
animal example.
*Continue this process for the square and rectangle.
*At the end, have different students explain the relationship between the shapes.

Lesson summary
Have the students drawl a picture to represent the relationship and then have each student explain their
picture. (i.e. Size them differently, drawl them inside each other etc)

Lesson Evaluation
Students will be evaluated by the pictures and the explanation of the pictures.
