2. Motivation:
Ask the pupils who among them are boy scouts or girl scouts.
Have them tell the activities they do in scouting.
Ask who among them have experience planting trees. Discuss briefly the
importance of trees in the environment.
Trees are very important. As the biggest plants on the planet, they give us
oxygen, store carbon, stabilize the soil and give life to the world’s wildlife.
Ask: What will happen if we cut down trees and never replace these with new
ones? Have you heard of the news of flash floods and landslides? What is one cause
of flashfloods and landslides?
B. Developmental Activities:

Ask: What is the activity about?
How many mahogany seedlings were brought to the campsite?
How many scouters were there?
Are there enough seedlings for the scouters? Why?
2. Performing the Activities
How many scouters are there in the campsite? 241 scouters
What operations do we use when we take away things? (Subtraction)
How will you write the number sentence for this problem?
Which will be the minued? the subtrahend?
241-229=N
3. Processing the activitiesand subtrahend?
Why it is important in subtraction to know which number is the minuend
In which place of value did you start subtracting?
What direction did you follow?
4. Reinforcing the concepth
Group Activity
Divide the the class into 3 groups. Provide them activity cards with questions
like:
a. How much greater is 527 than 263?
b. What is importance if you take away 3841 from 6257?
c. How much less is 287 7409?
5. Guided Practice:
Solve the following Expanded Form Method.
1. 3 942 – 719 = N
3. 6 475 – 2 436 = N
2. 7 363 – 247 = N
4. 32 365 – 2 217 = N
5. 25 136 – 4 018 = N
6. Generalization:
How do we subtract 3-4 digit numbers from 3-4 digit numbers with regrouping?
