Materials Required: Power point

Activity Time: 40 minutes

Concepts Taught: Shapes and basic geometric concepts

Relationships in Geometry grade 3-5

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

quadrilateral

*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.
