Materials Required: word-picture cards and powerpoint (not necessary)
Activity Time: 30 minutes
Concepts Taught: learing the relationships between quadrilaterals, parallelograms, rectangles and squares.

Relationships in Geometry grade 3-5

Lesson Objective:
Students will be able to show the correlation between quadrilaterals, parallelograms, rectangles and squares.

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

*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.
