A Lesson Plan Using the Concept Attainment Model

Concept Attainment Model

Subject: Mathematics

Grade Level: 5

Title: Prime VS Composite Numbers

Date: December 29/2017

Time: 50 minutes

Identifying the Topic: Prime Numbers

Focus: This lesson will focus on what makes a number prime and what makes it composite.

Learning Objectives:

At the end of the lesson, students will be:

ü  introduced to prime numbers

ü  able to differentiate between composite numbers and prime numbers

Required Prior Knowledge:

  ü The division process

  ü Divisibility rules

Examples and Non Examples:

List the examples and the non-examples in a table as follows:

YES	NO
3	4
7	8
13	10
5	9
2	15
19	22

Procedures:

   1.     Introduction: Introduce the students by telling them that the lesson is going to be discussed in a different way. Tell them that the teacher is going to give examples and non-examples about a secret concept that they would guess. (5 minutes)

   2.     Presentation of Data: the teacher will draw the YES/NO table on the board and students will start to guess the differences in order to reach the required concept. The teacher will not fill all the table in one shot. (10 minutes)  

   3.     Generating Hypotheses: Students would first think about the even and odd numbers. The teacher will then put the number “9” in the NO column and “2” in the YES column.  (10 minutes)

   4.     The Analysis Cycle: Students would eliminate the even/odd assumption. (5 minutes)  

   5.     Closure: After providing so many examples, the students will think together in pairs until they notice that the numbers in the YES column are only divisible by 1 and themselves. The teacher then tells them that those numbers are called the prime numbers. (10 minutes)

Assessment: (15 minutes)

Divide the students into pairs and give them numbers to apply the division rules and the division process on them to know which numbers are prime and which are not.
