4.1 and 4.3 Order of Operations

Focus Question: How can we ensure that we have clear communication when writing, evaluating, and interpreting number sentences?

The main goal of this lesson is to write and evaluate different number sentences that involve a combination of different operations.

Part 1: Do Now

For the do now task, you will need to complete "Check-Up #2" which focuses on your procedural fluency with all four integer operations.

Part 2: Dealing Up

Part 3: Evaluating Number Sentences

Part 4: Writing Number Sentences
In this part of the lesson, we will look at how to write number sentences to represent different "real-world" situations.  A couple of tips when writing number sentences are:

• Pay close attention to when it is appropriate to use negative integers.
• Remember that there are a couple of different ways to write the same number sentence.  Each different way tells a slightly different version of the story.

Here is what you MUST do before next class:

• Complete the "Order of Operations" assignment on Math XL For School.  
• Make sure that you show your work in your squarebook.
• Remember that you should get 100% on this assignment as you can redo each question until you get it correct.  Let me know if you get stuck.

Here is what you CAN do before next class:

• Complete the "Multiplying Integers" assignment on Math XL For School.
• Complete the "Dividing Integers" assignment on Math XL For School
