Note: Subject Integrated: HEALTH
Say: Mang Nestor can harvest 65 kilograms of
mangoes in a day. How many kilograms of mangoes
can he harvest in 3 days? ( 195 )
Let us analyze the problem:
a. How many kilograms of mangoes can he harvest in
3 days? ( 195)
b. What is asked for in the problem? ( the number of
mangoes Mang Nestor can harvest in three days)
c. What is the number sentence? ( 65 x 3 = n )
d. How can we solve the problem mentally?
For question letter d, call volunteer/volunteers to
answer the question orally.
Discussion on the expected answers.
Expected answer:
Solution 1
65
x3
3 x 5 = 15
3 X 60 = 180
Multiply mentally the ones
Multiply mentally the ones by tens.
Add mentally:
15 + 180 = 195
Solution 2-By distributive property
3 X 65 = (3 X 60) + (3 X5)
= 180 + 15
= 195
a. How did you find the activity? (engaging)
b. How did you get the product without the use of
paper and pencil? (by solving mentally)
E. Discussing new
concepts and
practicing new skills
