The question asked them to write the algebraic expression for 5 less than the product of 6 and 3. Before students begin, I remind them that math questions about our school can include time, money, people, area and perimeter, etc. 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.
Then I give the students 3 quiet minutes to list their thoughts. I circulate around the room and add challenges and supports as needed.
Warm Up 7 minutes The warm-up is designed to get students thinking mathematically. If students make a mistake and learn from it, we share this too. They can revisit these questions on their own. I start with simple expressions like 3 - c and then get more complex. The questions must have a math component, but students are reminded that math is part of almost anything - they just have to find it.
Who else uses codes? Today, I stay with this group for the first 3 questions to ensure the discussion is math based. These are going to be a bit tougher than the game, because you do write and evaluate expressions worksheets have multiple choices I ask a few to share the definition they find, then we create one to use as a class.
Sometimes, the English language can be a barrier to understanding the math. I encourage them to extend their understanding by writing their own phrases to write and evaluate expressions worksheets a round of "Numerical Expressions Millionaire", this time writing the algebraic expression and providing choices using English phrases.
I ask the students to write up an example of an algebraic expression on a scrap of paper and share with those around them. These groups are fluid, they are reassigned periodically based on topic, concept and student performance. I start with a think-a-loud to model how to use what you know about math to find clues to crack the code.
Adding in examples with more than one operation. This is a tough code to crack. I want my students to know that hard math is fun math. We answer any questions and clarify any misunderstanding.
Algebraic expressions are an example of one of these codes. This is posted where students see it - daily - as they enter the class each day. These lists will remain in the students math journals. I will come back to these questions as an assigned "I wonder warm-up" within the next few days.
This triggers yesterdays discussion about representing multiplication when there is a variable. There are 4 color groups. This warm- up activity is called I wonder I use a gradual release approach to completing this game.
I start with them, to help make sense of the directions and also to facilitate the discussion around the first question. You and your partners should be talking about the clues that you can find, before you write the algebraic expression.
To make sure every student is included, I call on a few students to share examples of questions that come to mind. I typically ask the same question.
Group Share 5 minutes I bring the students back to their own seats for a group share. 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.
First, you must use all the clues you know to understand what the expression means. This game will help us practice finding clues to help us understand the meaning of different expressions. Before we do, I explain that today we are going to practice writing and interpreting more expressions.
In my classroom the warm up is something to tackle, but not become frustrated with. What is a code?Writing and Evaluating Expressions Worksheet Evaluate each expression using the values m = 7, r = 8, 5.
