In the unit, you learned about the order of operations. What is the order of operations and why is it necessary? Performance Assessment Key and Scoring Rubric:
Warm Up 7 minutes The warm-up is designed to get students thinking mathematically. In my classroom the warm up is something to tackle, but not become frustrated with. This is posted where students see it - daily - as they enter the class each day. This warm- up activity is called I wonder Today students begin to generate a list of questions about our school.
The questions must have a math component, but students are reminded that math is part of almost anything - they just have to find it. Before students begin, I remind them that math questions about our school can include time, money, people, area and perimeter, etc.
To make sure every student is included, I call on a few students to share examples of questions that come to mind.
Then I give the students 3 quiet minutes to list their thoughts. After 3 minutes they share their thinking with a neighbor, and we have a few share out to the group. These lists will remain in the students math journals. They can revisit these questions on their own.
I will come back to these questions as an assigned "I wonder warm-up" within the next few days. Example from Student Journal Launch 5 minutes A numerical expression with variables can be intimidating.
Helping students see the fun in the challenge is important. I start this lesson with a conversation that gets students interested in what we will learn about today, and also helps them appreciate the challenge.
I want my students to know that hard math is fun math. Let's talk about codes for a few minutes. What is a code? Do any of you know or use any codes?
Who else uses codes? I explain to students that mathematicians use codes all the time. Algebraic expressions are an example of one of these codes. Students use a resource to look up the meaning of algebraic expression choosing from their text book, other math text books, or use the dictionary.
I ask a few to share the definition they find, then we create one to use as a class. I ask the students to write up an example of an algebraic expression on a scrap of paper and share with those around them.
I put a few examples of my own expressions on the board and ask the student to give it a thumbs up if it is an algebraic expression and a thumbs down if not. I start with simple expressions like 3 - c and then get more complex.
Adding in examples with more than one operation. Finally, I challenge them with 10b. This triggers yesterdays discussion about representing multiplication when there is a variable. This is a tough code to crack. So we break it down into pieces together.
Before we do, I explain that today we are going to practice writing and interpreting more expressions. Remember, you will have to be a detective and look for math clues to change "math talk" into English and English into "math talk".
I start with a think-a-loud to model how to use what you know about math to find clues to crack the code.
First, you must use all the clues you know to understand what the expression means.Evaluate an expression by substituting non-negative rational number values for letter variables in the expression.
