Lesson 1
Visualizing Numbers up to 5 000
Sir. Rei Marasigan
Alaminos Dist. -Laguna
Drill
Have pupils in the first row write a
number between 101 and 1 000 on
their "show-me board."
Review
Write numbers in words and in symbols.
Write the following in symbols, e.g.
1)eight hundred forty-eight
2)nine hundred ninety-nine
3)one hundred four
Write the following in words, e.g.
345
503
674
980
864
Motivation
Play a puzzle game. Provide each group of pupils
with sets of numerals
0, 1, 2, 3, 4, 5, 6, 7, 8 and 9. The puzzle is a number
(ranging from 101 to
1 000) written in bold figures. Ask pupils to
answer the questions that you will read.
Developmental Activities
Presenting the Lesson
Post the puzzles formed on the board.
 How are these numbers similar?
 How many digits are there?
 What is the biggest place value in the
numerals?
Performing the Activity
Have the pupils use flats, longs, and
squares to illustrate/visualize each
number.
10 flats (10 hundreds) = 1 block (1
thousand)
Suppose you count on from
1 000, what would be the next
number?
Thousands Hundreds Tens Ones
1 0 0 0
Using blocks, flats, longs and squares, 1 000 has how many
loose squares? How many longs? flats? blocks?
How many is 1 000 in hundreds? tens? ones?
1 000 = 10 hundreds
= 100 tens
= 1 000 ones
If we count from one to one thousand and add
1, we have one thousand one.
We are going to visualize other numbers using
flats, longs and squares.
b. 3 627
3
blocks 6 flats 2 longs 7squares
3 000 + 600 + 20 + 7
Processing the Activity
• What do the blocks represent? the flats? the
longs? the squares?
• When we add one square to 1 000 blocks, how
much do we get?
• In the representation, how much is 2 blocks, 4
flats, 2 longs, and 5 squares?
• How many blocks, flats, longs, and squares is
3 627?
• Can you now visualize big numbers using this
representation?
Reinforcing the Concept
Divide the pupils into 10 groups. Give each group a chart
with the title
"My 2 001 – 2 100 Chart”. Have them complete the chart:
2 001 – 2 100, 2 101 – 2 200, and so on.
Summarizing the Lesson
• How could we visualize numbers from
1 001 – 5 000?
• What helps us visualize the numbers?
Applying to New and Other Situations
Gamitin ang sandaanan (flats), sampuan (longs),
at isahan (squares) upang maipakita ang
sumusunod na bilang.
1) 1 375
2) 2 083
3) 3 260
4) Isang libo, limang daan, at labing walong
punla ng mahogany
5) Dumalo sa konsiyerto ang apat na libo,
dalawang daan, at tatlumpu’t isang
manonood. Paano mo maipakikita ang bilang
na ito gamit ang sandaanan (flats), sampuan
(longs), at isahan (squares). Isulat ang inyong
sagot sa sagutang papel.
Evaluation
A. Ipakita ang katumbas na bilang ng mga
sumusunod gamit ang sandaanan (flats), 7
sampuan (longs), at 4 na isahan (squares).
1) 2 217
2) 3 248
3) 3 760
Gamitin ang graphing paper. Iguhit at kulayan
ang katumbas na bilang sa ibaba. Isulat ang
angkop na bilang sa patlang.
1)1 block, 8 flats, at 2 squares
______________
2) 2 blocks, 5 flats, 7 longs, at 4 squares

  • 4. Motivation Play a puzzle game. Provide each group of pupils with sets of numerals 0, 1, 2, 3, 4, 5, 6, 7, 8 and 9. The puzzle is a number (ranging from 101 to 1 000) written in bold figures. Ask pupils to answer the questions that you will read.
  • 5. Developmental Activities Presenting the Lesson Post the puzzles formed on the board.  How are these numbers similar?  How many digits are there?  What is the biggest place value in the numerals?
  • 6. Performing the Activity Have the pupils use flats, longs, and squares to illustrate/visualize each number.
  • 7. 10 flats (10 hundreds) = 1 block (1 thousand) Suppose you count on from 1 000, what would be the next number?
  • 8. Thousands Hundreds Tens Ones 1 0 0 0 Using blocks, flats, longs and squares, 1 000 has how many loose squares? How many longs? flats? blocks? How many is 1 000 in hundreds? tens? ones? 1 000 = 10 hundreds = 100 tens = 1 000 ones
  • 9. If we count from one to one thousand and add 1, we have one thousand one. We are going to visualize other numbers using flats, longs and squares.
  • 10. b. 3 627 3 blocks 6 flats 2 longs 7squares 3 000 + 600 + 20 + 7
  • 11. Processing the Activity • What do the blocks represent? the flats? the longs? the squares? • When we add one square to 1 000 blocks, how much do we get? • In the representation, how much is 2 blocks, 4 flats, 2 longs, and 5 squares? • How many blocks, flats, longs, and squares is 3 627? • Can you now visualize big numbers using this representation?
  • 12. Reinforcing the Concept Divide the pupils into 10 groups. Give each group a chart with the title "My 2 001 – 2 100 Chart”. Have them complete the chart: 2 001 – 2 100, 2 101 – 2 200, and so on.
  • 13. Summarizing the Lesson • How could we visualize numbers from 1 001 – 5 000? • What helps us visualize the numbers?
  • 14. Applying to New and Other Situations Gamitin ang sandaanan (flats), sampuan (longs), at isahan (squares) upang maipakita ang sumusunod na bilang. 1) 1 375 2) 2 083 3) 3 260 4) Isang libo, limang daan, at labing walong punla ng mahogany
  • 15. 5) Dumalo sa konsiyerto ang apat na libo, dalawang daan, at tatlumpu’t isang manonood. Paano mo maipakikita ang bilang na ito gamit ang sandaanan (flats), sampuan (longs), at isahan (squares). Isulat ang inyong sagot sa sagutang papel.
  • 16. Evaluation A. Ipakita ang katumbas na bilang ng mga sumusunod gamit ang sandaanan (flats), 7 sampuan (longs), at 4 na isahan (squares). 1) 2 217 2) 3 248 3) 3 760
