Week 2 Group 1 Post

Members Present – Toushayiah, Thomas, Pavlo, Allison, Salem, Issac

STANDARD H1: Problem 8

  • Context – Find the value of the following equation
  • Observations – In the equation operations being used are Addition, Subtraction, Multiplication, and also using parentheses and brackets
  • Questions – What operation comes first? Does operations change because of the parenthesis? Are () and [] different depending on the equation?
  • Strategies – Add what’s in the inner parenthesis, multiply in the parenthesis, subtract in the parenthesis, and multiply what’s outside the parenthesis.
  • Concepts – You need to be able to understand Order of Operations and PEMDAS
  • Conclusion – The value is -72

STANDARD H2: Problem 3

  • Context – Find the value of the following equation
  • Observations – There is a fraction, exponents, and negative numbers
  • Questions – How do I solve what’s in the parenthesis? Do I solve the exponents first? Will the negative numbers affect my answer?
  • Strategies – Solve the exponents in the numerator and denominator of the parenthesis, Divide the numerator and denominator in the parenthesis, and Solve the exponent outside the parenthesis
  • Concepts – Concepts needed to understand and solve the problem are the order of operations, exponents, and PEMDAS
  • Conclusion – The answer is 64

Standard 1- Question 8: 4[15-3(3+8)]

  1. Context

This problem deals with multiplication, addition, subtraction and the order of operation.

2. Observations

Brackets and parentheses appear, addition and subtraction appear, multiplication appears.

3. Questions

What does the order of operation tell us to do? What does it mean when there’s 2 types of parentheses? Will our answer be positive or negative?

4. Strategies

Evaluate parentheses first and follow the order for operation.

5. Concept

Order of operation

6. Conclusion

4[15-3(3+8)]

Parentheses: 4[15-3(11)]

Multiplication: 4(15-33)

Subtraction: 4(-18)

Final Answer: -72

Standard 2- Question 3: ( -4^3/-2^3)^2

  1. Context

This problem deals with negative integers, division and exponents.

2. Observations

Negative integers appear, division appears and exponents appear.

3. Questions

What does the order of operations tell us to do? What does it mean when there’s 2 sets of exponents? Will our answer be positive or negative?

4. Strategies

Evaluate parentheses first and follow the order of operations.

5. Concepts

PEMDAS, simplify the division inside the parentheses.

6. Conclusion

(-4^3/-2^3)^2

-4^3= -64

-2^3= -8

-64/-8= 8

8^2= 64

Final Answer: 64

OpenLab assignment: Week 2 group post

Due Monday, September 11, 11:59pm

Animated gif of Marge, Homer, and Lisa Simpson. Homer takes a clipboard from Lisa and says, "Yeah, it's a good group."

Recall the first two HOT topic standards:

  • H1: Evaluate an expression using order of operations (may include fractions but no exponents)
  • H2: Evaluate an expression using order of operations (may include integer exponents)

As a group, find the two questions on the HOT Topics question list form Week 1 that align with these two standards (there was only one version of the HOT Topics question list in Week 1, but there will be multiple versions in the future).

As a group, for each of these two questions, work through the 6-point problem-solving framework carefully. Have a group member write up your group’s complete answers for each of the two questions (it can be a different member for each question but all group members must approve of the work).


The secretary will post the group’s work with these instructions:

  • Title of post: Week 2 group [n] post (where [n] is replaced by your group’s number)
  • Category of post: Week 2 group post
  • Post must include:
    • Names of members present
    • Answer for each of the 6-points for the Standard H1 question
    • Answer for each of the 6-points for the Standard H2 question

There are many different ways to correctly address all 6 points in the problem-solving framework. We’ll see how different each of the groups’ work looks!
