Lesson 1: Numbers from 101 to 1000

Digits – are used to count or write large numbers 2 hundreds is 200. Like counting from 1 to 100, when you reach 99, the next number is 100. So count from 101 then after 199, is 200. Count from 201-300 3 hundreds is 300 – Count from 301-400 4 hundreds is 400 – Count from 401-500 5 hundreds is 500 – Count from 501-600 6 hundreds is 600 – Count from 601-700 7 hundreds is 700 – Count from 701-800 8 hundreds is 800 – Count from 801-900 9 hundreds is 900 – Count from 901-1,000 10 hundreds is 1,000 Next to hundreds is thousands. From 1,001 to 1,999 are 4-digits

Emphasize:  Next to hundreds is thousands.  10 hundreds is equal to 1,000.

Lesson 2: Place value of four-digit numbers

The position of the digit tells about its value. The first number from the right of a four-digit number represents the ones. The second is tens. The third is hundreds. The fourth is thousands.

Example: seven thousand five hundred fifty-three The value of 7 is 7,000 The value of 5 is 500 The value of 5 is 50 The value of 3 is 3

Lesson 3: Writing Numbers in Expanded Form Numbers can be written in expanded form to show the place value of each digit.

The place value of 0 is not anymore written in expanded form. Example: 1. 5428 – 5,000 + 400 + 20 + 8 2. 4,609 – 4,000 + 600 + 9

3. 2,013 – 2000 + 10 + 3

Lesson 4: Comparing Numbers

Greater than or Less than to compare numbers.

We use the symbol ˃ for greater than and ˂ for less than.

˂ or ˃ always points to lesser number.

Example: 2,864 is greater than 2,861 or 2,864 ˃ 2861 2,861 is less than 2,864 or 2,861 ˂ 2,864

YOUNG JI INTERNATIONAL SCHOOL/COLLEGE

Lesson 5: Ordering Numbers

In ordering whole numbers: - Align the digits by place value - Compare the digits in each place, starting with the greatest place. - Arrange the numbers in order from greatest to least or from least to greatest. Example: Write the numbers in order from greatest to least or least to greatest.

4,936

Look at the digits in the thousands place.

4,273

They are the same. Look at the digits in the

4,487

hundreds place. What is the highest? What

4,762

is the least? So if you arrange the numbers

4,879

from greatest to least the numbers are: 4936; 4,879; 4,762; 4,487; 4,273 In order from least to greatest, the numbers are: 4,273; 4,487; 4,762; 4,879; 4936

Lesson 2: Addition With Regrouping

In adding numbers with regrouping: 1. Add the ones. If the sum is more than nine, regroup and add the ten in the tens place. 2. Add the tens. If the sum is more than ten, regroup and add the ten in the hundreds place 3. Add the hundreds.

Example: A bookstore has 156 books in one shelf and 168 books in another shelf. How many books are there in all?

Add 156 and 168. H

Lesson 4: Subtraction Without Regrouping

Subtraction - is the inverse or opposite of addition Minuend - is the greater number from which another number is taken Subtrahend - is the number take away Difference - is the answer in subtraction

-

- subtract the digits in the ones place. 7 – 4 = 3.

4

Write 3 in the ones place.

3

-Subtract the digits in the tens place. 2 – 1 = 1. Write 1 in the tens place.

27

 minuend  the greater number that which another number is taken.

14  subtrahend  the number taken away from the minuend. 13  difference  the answer in subtraction. YOUNG JI INTERNATIONAL SCHOOL/COLLEGE

PAGE 33


The number sentence is read as 27 minus 14 equals 13. Minus sign ( - ) is used in subtraction. To check if your answer is correct use addition because subtraction is the inverse or opposite of addition. Let’s try to see: 27

minuend

13

addend

subtrahend

+14

To check if subtraction is correct, add the difference and the subtrahend to get the minuend.

YOUNG JI INTERNATIONAL SCHOOL/COLLEGE

PAGE 34


Lesson 5: Subtraction With Regrouping

If the digit in the subtrahend is greater that the minuend in the same place value, use regrouping.

Regrouping means taking 1 ten to the next place value and adding it to the digit in the minuend. Example: 6

- Subtract digits in the ones place. 2-4 cannot be Regroup by taking 1 ten in the tens place and add to 2 So, 12-4 = 8.Write 8 in the ones place

-Subtract the digits in the tens place. 3-5 cannot be. Regroup 3 by taking 1 ten in the hundreds place and add to 3. So 13-5 = 8. Write 8 in the tens place. -Subtract the digits in the hundreds place. 1-6 cannot be.

Regroup 0 by taking 1 ten in the thousands place and add to 0. So 10-6=4. Write 4 in the hundreds place. -Subtract the digits in the thousands place 6-3 = 3 The difference is 3,488.

Example:

Lesson 7: Multiplying one-digit multiplier

Multiplying a number by 1 to 10 is the same as skip counting by the number. The products of a number multiplied by 1 to 10 are multiples of that number.

YOUNG JI INTERNATIONAL SCHOOL/COLLEGE

Activity Answer the following:

YOUNG JI INTERNATIONAL SCHOOL/COLLEGE

PAGE 39


Lesson 8: Property of Multiplication

Identity Property of multiplication Shows that any number multiplied by one (1) is the same number. Example: There is only 1 group of 4, so 1 group of 4 is 4. 1x4 = 4 or 4x1 = 4 There is only 1 group of 5, so 1 group of 5 is 5.

1x5 = 5 or 5x1= 5

Zero Property of Multiplication shows that zero multiplied by any number is zero. Example: 6x0 = 0 Order Property or Commutative Property of Multiplication shows that changing the order of the factors does not change the product. Example: 7x4 = 28 and 4x7 = 28; So, 7 x 4 = 4 x 7

Lesson 3: Symmetry

Line of symmetry – a figure is symmetrical if it can be folded so that one part matches the other part. The fold or line that divides the figure into two equal parts.

Tessellation or tilting – is made from congruent or equal figures placed so they completely cover a surface without overlapping or leaving gaps. You can turn or flip the shades to create a design.
