Grade 7 Math: Rational Numbers Operations

This lesson plan summarizes a mathematics lesson on operations of rational numbers for 7th grade students. The lesson plan defines rational numbers and the objectives of performing operations on rational numbers and relating them to real life situations. It discusses proper and improper fractions, and how to add fractions with the same or different denominators. Examples are provided. Students will work in groups on sample word problems and discuss how to apply rational number operations to real life. At the end, students will complete an individual evaluation with fraction addition problems to solve.

OBJECTIVES (COTA #1)

At the end of the lesson, the students should be able to:

a. define rational numbers;


b. relate operations on rational numbers in real life situation; and
c. perform operation on rational numbers.

II. SUBJECT MATTER

 REFERENCE/S
o

MATERIALS: (COTA #2)


o Powerpoint presentation
o Chalkboard
o Chalk

 PVMGO
Prior knowledge (COSLA #15)

III. PROCEDURE

A. DAILY ROUTINES (COTA #5)

 Classroom Management
B. MOTIVATION(COTA#5)(COTA#6)(COSLA#7)(COSLA#8)(COSLA#9)(COSLA#10)(COSLA #11)
 If you and three of your classmates are going to eat pizza in the past food chain, how will you
divide this pizza?

C. PRESENTATION (COTA#1)

The teacher gives the competencies which the students should be able to learn at the end of the
class.

a. define rational numbers;


b. relate operations on rational numbers in real life situation; and
c. perform operation on rational numbers.

D. DISCUSSION (COTA #3)

Proper Fraction
In proper fraction, the numerator is smaller than the denominator.

Example:

In adding proper fraction with the same denominator we are going to add both the numerators and
copy the denominator. For example:

1 2 3
1. + = 1+2
4
=
4 4 4
Another example;

8 8 8+8
2. + = =1
16 16 16

2 3 2+3 5 1
3 . + = = or 1
4 4 4 4 4
Improper Fraction
In improper fraction, the numerator is larger than denominator.

Example:

In adding improper fraction, with the same denominators we are going to add both the numerators
and copy the denominator. For example:

3 5 8
1. + = or 4
2 2 2

9 4 9+4 13 3
2. + = = or 2
5
5 5 5 5

They called improper fraction “improper” because it is not the proper way to leave your answer.
To convert improper fractions to mixed fraction, we should follow these steps:

1. Dive the numerator by the denominator;


2. Write down the whole number answer; and then
3. Write down any remainder above the denominator.

Example:

4 4 4+4 8 2
+ = = =2
3 3 3 3 3

E. APPLICATION (COSLA #7)


Group the students into 4 groups and let them answer the given problem on the board.

1. John walked 1⁄4of a mile yesterday and 3⁄4 of a mile today. How many miles has John
walked?
2. Sam bought 7⁄4 kg of sugar from one shop and 5⁄4kg of sugar from the other shop. How
much sugar did he buy in all?

F. GENERALIZATION (COTA #3)(COSLA #11)(COSLA #13)

1. How will you relate operations on rational numbers in real life situation?

The students can also ask some questions to the teacher to have a clarification for the
topic. (COSLA #12)
