LESSON 7: Ordering Numbers up to 100 000

DISCOVER

How do we arrange larger numbers?

Learn about increasing order and decreasing order.

Watch this

Remember:

Increasing order– from least to greatest.

Example:

(20,000) (20,001) (20,002) (20, 003)

Decreasing order– from greatest to least.

Example:

(20, 003) (20,002) (20,001) (20,000)

LET’S MOVE!

Activity 1

Arrange the following numbers

1.) Increasing order:

2.) Decreasing order:

(35, 854) (35, 654) (65, 354) (35, 354)

3.) Increasing order:

4.) Decreasing order:

(45, 654) (33, 844) (64, 351) (33, 214)

5.) Increasing order:

6.) Decreasing order:

(27, 654) (25, 844) (23, 351) (22, 213)

7.) Increasing order:

8.) Decreasing order:

(17, 634) (25, 842) (33, 328) (42, 214)

9.) Increasing order:

10.) Decreasing order:

(54, 635) (54, 845) (54, 325) (54, 215)

LESSON 6: Comparing Numbers up to 100, 000 Using Relational Symbols

DISCOVER

How do we compare large numbers?

>, < and =. What are these symbols stand for?

Symbols Meaning Example
>“greater than” – used when one value is bigger than another.
 123 > 23
<“less than” – used when one value is smaller than another.
23 < 123
= “equal” – When two values are equal.
23 = 23
  • To remember which way around the “<” and “>” symbols go:

BIG > small

small < BIG

  • Always start comparing from the highest place values.

example:

– Both numbers has ten thousands place as their highest place value. Start from the ten thousands place.

87, 654 and 49, 654

is 87, 654 > 49, 654

Read: 87, 654 is greater than 49, 654.

– If both ten thousands places has the same digit then you can proceed to the next highest place value.

87, 654 and 89, 654

is 87, 654 < 89, 654.

Read: 87, 654 is less than 89, 654.

LESSON 5: Rounding Numbers to the Nearest Thousands and Ten Thousands

DISCOVER

Why do we round off numbers?

What are the steps in rounding off numbers?

Watch this.

From Cherry’s Classroom YouTube Channel.

Guide to rounding numbers:

  1. Rounding Digit -Identify the rounding digit according to its place value.
  2. Round Up or Round Down– decide when to round up or round down. Round down when the digit at the right of the rounding digit is less than 5. Round up if the digit at the right of the rounding digit is 5 or more than 5.
  3. Zeros – Replace all numbers to right of the rounding number with Zero.

LESSON 4: Reading and Writing Numbers up to 100 000 in Symbols and in Words

DISCOVER

100 000.

How do we read this?

How do we write it in words?

Watch this.

From Cherry’s Classroom YouTube Channel

Remember the following in reading numbers in symbols and in words.

  • Read from left to right.
  • Number + Period ( In every period, read the number then the period in singular form. No need to read the period when its in the Ones Period.)

Remember the following in writing numbers in symbols and words.

  • Always hyphenate 2-digit numbers 21 up to 99 when writing them out as words. These are compound numbers.
  • 2-digit numbers like 11 up to 19, 10 20, 30, 40, 50, 60, 70, 80, 90 are not compound numbers. These numbers don’t need to be hyphenated.
  • Use a space or a comma between periods.
