1. 1. Mathematics 5 Visualizing Numbers up to 1 000 000 with Emphasis on Numbers 100 001
2. 2. What objects can we use to visualize numbers from 100 001 to 1 000 000?
3. 3. Read the numbers orally.
4. 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. 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.
6. 6. 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 earthly beads/lower group of beads? 1 5. Did you notice a grouping of beads?
7. 7. 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.
8. 8. 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.
9. 9. GROUP I - 5 634 210 GROUP II – 2 184 623 GROUP III – 13 540 211 GROUP IV – 25 134 000
10. 10. Can we use the abacus in visualizing large numbers? Is it easy to manipulate? Are number discs useful in representing
11. 11. Give the number represented by the discs in the abacus.
12. 12. 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
13. 13. 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.
14. 14. 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.
15. 15. 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
16. 16. 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
