A certain town in Russia records the following
temperature reading for 5 days: -5°C of on the
first day, -6°C for three consecutive days, and -
7°C on the fifth day.
Write your answer in a blue paper if it is
positive. And in Red paper if your answer is
negative.

B. LESSON PROPER
1. ACTIVITY
I prepared an activity that you need to answer.
For this activity, you student will be grouped into
2. You have 5 minutes to work on this activity.
You are free to choose a representative who will
present your group work on how you come with
your answers.
Group 1
(+) x (+) = (+) (-) x (-) = (+)
(+) x (-) = (-) (-) x (+) = (-)
Processing question:
1. What is the sign of the product did you get
when you multiplied two integers with the
positive sign?
2. What is the sign of the product of a negative
and positive integer?
Group 2
(+) ÷ (+) = (+) (-) ÷ (-) = (+)
(+) ÷ (-) = (-) (-) ÷ (+) = (-)
Processing question:
1. What is the sign of the quotient when integers
with positive and negative signs are divided?
2. What will be the sign of the quotient of two
negative integers?
2. ANALYSIS
Time’s up!
Did you finished the activity well? Yes, Sir.
Very good.
1. 3 x 49 = 147
2. (-14) x (-5) = 70
3. 50 x (-9) = -450
Processing question:
1. What is the sign of the product did you
get when you multiplied two integers with
the same sign?
- positive sign
2. What is the sign of the product of a
negative and positive integer?
Very good, group 1. - negative
Group 2, your turn to present your work.
Group 2
Direction: Perform the indicated operation
and use the diagram above in formulating
your final answer.
1. 60 ÷(-3) ÷4 = -5
2. 125 ÷5 = 25
3. (-500) ÷(-5) ÷(-20) = 5
Processing questions:
1. What is the sign of the quotient when
integers with different signs are divided?
- negative sign
2What will be the sign of the quotient of
two negative integers?
- positive
Good job group 2.
Give yourself a big round of applause.
Steps in Multiplying
1. Identify which is Multiplicand and Multiplier.
Multiplicand is the first number in the
equation.
Multiplier is the second number or the
number after the multiplication symbol
Ex. 6 x 3
Multiplicand Multiplier
Or
III II I I I I I I I I I I I I I
1,2,3 4,5,6 7, 8,9 10 11 12 13 14 15 16 17 18
- 6 colums represents the multiplicand.
- 3 element in eah column represent the
multiplier.
Steps in Dividing
1. Identify which is the Dividend and Divisor.
Dividend is the first number and the
number to be divided.
Divisor is the number after the division
symbol and the number where the
dividend will be divided.
Ex. 6 ÷ 3
Dividend Divisor
Or
I I I I I I
1 2 1 2 1 2
- 3 columns represents the divisor.
- 2 element in each column represents the
quotient.

IV. EVALUATION
Direction: Solve the following problems.
1. The school canteen reported losses of ₱250 in sales per day. How much was the total loss in
five days?
2. Rosette owes the veterinarian ₱840. She cannot afford to pay so she asked her family for support.
Each member decided to give her ₱120. How many members contributed?
3. The weather monitoring center observed that for the past two years the temperature in Benguet
Province dropped each month from October to February by 1°C. If the temperature in October was
20°C, what would be the temperature in February the following year? What would be the average
temperature of from October to February?
4. A group of three students initially pooled a fund of ₱1 000 to buy materials for their projects.
They three bought some spray paints worth ₱220, two markers worth ₱43 each, and 10 pieces of
cartolina worth ₱12 each. To ready them for any additional expense they may incur in the next
days, they each added ₱100 to the fund. How much money is in their fund now?
V. ASSIGNMENT
1. Research Properties of Integers
2. Differentiate each of the properties.
