Learning goals 

At the end of this lessons I can:

• Simplify algebraic expression by adding like terms

Simplify the following:
15a + 3b - 6a + 10b

Collecting like terms

Simplify the following:

15a + 3b - 6a + 10b = 

15a - 6a + 3b + 10b = 

9a + 13b =

Bob says that 

4 - (p + p + p) = 4 - p + p + p 

Do you agree with Bob? 

Do you agree with Bob?
Why or Why not?

Collecting like terms

4 - (p + p + p) = 

4 - (3p) = 

4 - 3p

 4 - p + p + p =

4 + p

Bob is incorrect!

4 - (p+p+p) ≠ 4 - p + p + p

How many can you CORRECTLY simplify in 5 minutes? 

How many can you CORRECTLY simplify in 5 minutes? 

= 9x + 6y

= 8a + 8b

= 4u + 3v

= 8p + 8q

= 6m + 8n

= 7u + 12V

=11b + 5c

= 2a + b

= 8b

= 7p

Work on the slides with the appropriate color: 

- Got the question right                               I really want a challenge!

- Got the question right                               I think a bit more practice will help me!

- Got the question incorrect/correct     I think more practice will help me! I                                                                                         would like some more help.
