You Try 1--Add the following expressions vertically to rewrite in standard form.

(2a+3b-4)+(5a+4b-2)

CFS:
#1: Accurately identifies like terms
#2: Accurately simplifies to standard form

1

You Try 2--Subtract the following expressions vertically to rewrite in standard form.

(10x-4y)-(6x-y)

CFS:
#1: Accurately identifies like terms
#2: Accurately rewrites as addition
#3: Accurately simplifies to standard form

1

Standard--Add/subtract the expressions vertically to put into standard form.

REMEMBER that subtracting means the opposite for everything in the second group.

(6c-4)-(c-3)

CFS:
#1: Accurately identifies like terms
#2: Accurately rewrites as addition
#3: Accurately simplifies to standard form

MEDIUM PROBLEMS

1

Standard--Add/subtract the expressions vertically to put into standard form.
You can show work just in your notebook.

(5x+2y+8z)+(4x+4y-5z)

CFS:
#1: Accurately identifies like terms
#2: Accurately simplifies to standard form

1

Add/subtract the expressions vertically.

Be careful about the order of the terms. You can show work just in your notebook.

(3a+20b-12c)-(3a-2c+6b)

CFS:
#1: Accurately identifies like terms
#2: Accurately rewrites as addition
#3: Accurately simplifies to standard form

SPICY--Try if you have time.

Simplify the expressions to standard form by adding vertically.

Be VERY careful about the order of the terms. You can show work just in your notebook.

(3y-2x+8z-4)+(5x-3z+10y+8)

CFS:
#1: Accurately identifies like terms
#2: Accurately rewrites as addition
#3: Accurately simplifies to standard form

4

Add/subtract the expressions vertically.
You must show all work on Formative.

(4f+2g-3)-(3f+8g-6)

CFS:
#1: Accurately identifies like terms
#2: Accurately rewrites as addition
#3: Accurately simplifies to standard form
