ONLINE HOMEWORK
Professor Oaks Dilemma
Good day, Grade 4! Im Professor Oak from Pallet town. Im a Pokmon professor and researcher. I encountered countless number of Pokmon already. However, Im afraid that I can remember them all with my age. So, I recorded their data in a device called Pokdex
Professor Oaks Dilemma
However, I think theres quite a problem I accidentally mixed-up some of Pokmon data. Some ORDER got mixed-up. Maybe you can help me fixing it by ORDERING the Pokmon in ASCENDING ORDER, by their number
Professor Oaks Dilemma
By the way, do you know how to ORDER NUMBERS?
Worry no more! Ill explain that to you. So better pay attention, ok?!
ORDERING WHOLE NUMBERS
2 Orders:
Ascending or Increasing Order
Descending or Decreasing Order
ORDERING WHOLE NUMBERS
ASCENDING or INCREASING ORDER
- The numbers are arranged from LOWEST to HIGHEST
ORDERING WHOLE NUMBERS
Example: The monthly budget (in pesos) of Dela Cruz Family in 4 months are: 34,283 pesos, 29,304 pesos, 32,829 pesos, and 30,273 pesos. Arrange their monthly budget in ASCENDING ORDER
ORDERING WHOLE NUMBERS
DESCENDING or DECREASING ORDER
- The numbers are arranged from HIGHEST to LOWEST
ORDERING WHOLE NUMBERS
Example: [insert students name]s weekly baon for 4 weeks are 827, 847, 839, and 902 pesos. Arrange his/her weekly baon in DESCENDING ORDER
Professor Oaks Dilemma
Are we clear about ORDERING WHOLE NUMBERS?
Can you now lend me a hand in fixing my Pokdex?
Ok, we need to arrange them in ASCENDING ORDER
Ok, we need to arrange them in DESCENDING ORDER
Professor Oaks Dilemma
Thank you so much for helping me fix my Pokdex! See you soon!
