1. Mathematics
5 Visualizing
Numbers up to 1
000 000 with
Emphasis on
Numbers 100 001

2. What objects
can we use to
visualize numbers
from 100 001 to 1
000 000?

3. Read the numbers orally.

4. Show the following numbers
using your cut-outs of
number discs.
1. 203 746
2. 109 652
3. 784 100
4. 521 034
5. 430 865

5. Are you familiar with
the use of abacus in
mathematics lessons?
Today we are going to
watch a video on the
basic rules of using an
abacus.

7. 1. What did you learn from the video?
2. When do we start counting the
beads? (Expected answer: When the
bead touches the center beam or the
reckoning bar)
3. What is the value of each bead in the
heavenly beads/upper group of beads?
5
4. What is the value of each bead in the

5. Did you notice a grouping of beads?

8. To further understand it, hold your
abacus.
Let’s take 34 867 as example.
Assign a place value to each pole of
the abacus.
Move the beads to show the
numbers.

10. ACTIVITY
Directions:
1. Using your abacus, show the
following numbers.
2. Use number discs to represent
these numbers.
3. Compare.
4. Report the result in front of the
class.

11. GROUP I - 5 634
210
GROUP II – 2 184 623
GROUP III – 13 540
211
GROUP IV – 25 134
000

12. Can we use the
abacus in visualizing
large numbers?
Is it easy to
manipulate?
Are number discs
useful in representing

13. Give the number represented by the discs in the
abacus.

17. Use number discs to show the
following numbers.
1. 2 561 234
2. 3 143 025
3. 1 342 187
4. 4 026 531
5. 5 236 410

18. Answer this.
Around 4, 163, 045 vehicles from
the country emit pollution that causes
different respiratory illnesses. Draw
the correct beads in the blank abacus
given below. Also show the given
number using number discs.

19. How do we visualize numbers up
to 10 000 000?
Aside from number discs
which can be used to show
numbers from 1 000 001 to 10
000 000, we can also manipulate
the abacus to visualize them.

20. Using number discs,
show the following
numbers.
1. 3 718 000
2. 2 024 123
3. 10 000 000
4. 4 120 572
5. 5 004 036

21. Using the numbers in the
Assessment, represent them using
the abacus.
1. 3 718 000
2. 2 024 123
3. 10 000 000
4. 4 120 572
5. 5 004 036
