1. List the terms in the expression below, place a comma between each term.
19cd + 6d^2 + 8
2. List the coefficients in the expression below, place a comma between each coefficient.
7y + 13ab^2 + x

Terms are separated by + or  signs.
1. The first term is 19cd.. Can you find the other two?
2. Coefficients are the numbers in front of the letters.
x can be written as 1x, so it has a coefficient of 1.
Can you find the others? 
I don't understand

my son does'nt understand , me too.

Terms are a combination of letters and numbers written next to each other.
They are separated by + or  signs.
3x + 4y + 9
represent 3 terms:
3x
4y
9
The coefficients are the numbers in front of the letters
3 and 4 are coefficients
9 is usually called a constant because it is just a number without a letter. 
So, 1. 19cd , + 6d^2 , + 8 ,
2. 7
13
is it correct 
2. 7 , y + 13 , ab^2 + x
7
13 
1. 19cd , + 6d^2 , + 8 ,
19cd
6d^2
