Math/Addition lesson pack.

Math: Adding numbers up to 20

hello guys again!

today we gonna study about ADDITION!!

first what is addition??

Addition is...

Addition is one of the four basic operations of arithmetic, the other three being subtraction, multiplication and division. The addition of two whole numbers results in the total amount or sum of those values combined.

now you know addition!!

And its meaning...

Now lets practice the parts!!

Parts of addition

• 1. Addend - In addition, the addends or the summands are numbers or terms being added together. ...

• 2. - Equal sign, The equal sign indicates that the two halves of the equation are equivalent.

• 3. Sum - The sum in addition sentence is the totals of the addends. For example, in 10 + 6 = 16, the sum is 16.

now we know the parts of addition!!

now it's full meaning is here:

FULL MEANING OF ADDITION:

The AddendIn addition, the addends or the summands are numbers or terms being added together. For example, 10 + 6 = 16, 10 and 6 are the addends of this equation.

The Equal SignThe equal sign indicates that the two halves of the equation are equivalent. For example, in the addition sentence, 10 + 6 = 16, the is equal is denoted with two short horizontal strokes.

The SumThe sum in addition sentence is the totals of the addends. For example, in 10 + 6 = 16, the sum is 16.

Understanding the properties of addition is important because it guides you to work with numbers more effectively.

1. Operation in addition:

Addition is commutative - This property states that the positions of numbers in an equation does not affect the final answer. For example, 4 + 5 is the same as 5 + 4. This property applies to addition of numbers, no matter how large the group of numbers is.

2. Operation

Associative Property -This property applies to complex equations that involve the use of brackets, braces and parenthesis to separate group of numbers. In addition, we can move the brackets around without affecting the ultimate answer. For example, (4 + 6) + 2 = 4 + (6 + 2).

Last Operation

Identity Property -The identity property states that the sum of a number with zero is equivalent to the number itself. For example, 5+ 0 = 5. The number zero is called identity number because it does affect other numbers during the addition.

When a student is adding large groups of numbers, remind them that the number zero does not affect other numbers in the equation.

now you know fully about addition
