Writing and evaluating expressions lesson plan

I ask the students to write up an example of an algebraic expression on a scrap of paper and share with those around them. So we break it down into pieces together.

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. Example from Student Journal Launch 5 minutes A numerical expression with variables can be intimidating.

Attend to Precision since students must precisely match expressions with the verbal situation. This is posted where students see it - daily - as they enter the class each day. 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.

This triggers yesterdays discussion about representing multiplication when there is a variable. I set the expectation before they begin. First, you must use all the clues you know to understand what the expression means. Write their examples on chart paper to be displayed during the lesson.

I encourage them to extend their understanding by writing their own phrases to create a round of "Numerical Expressions Millionaire", this time writing the algebraic expression and providing choices using English phrases. Warm Up 7 minutes The warm-up is designed to get students thinking mathematically.

Prior Knowledge - the activation of prior knowledge is addressed, in detail, in the Formative Assessment section of this lesson plan.

These lists will remain in the students math journals. Feedback to Students Common Error: Zoom in your LCD projector or your desktop screen so that the phrase does not show, only the multiple choice expressions.

I ask a few to share the definition they find, then we create one to use as a class. Finally, I challenge them with 10b.

Expressions, Phrases and Word Problems, Oh My!

Ask the students to give you as many clue words as they can think of that tell them what operation to use in a problem. Distribute copies of the assessment to students individually. Helping students see the fun in the challenge is important.

Writing Algebraic Expressions Day 1 (of 2)

They will be analyzing phrases and deciding which expression represents that phrase. This game will help us practice finding clues to help us understand the meaning of different expressions. The questions must have a math component, but students are reminded that math is part of almost anything - they just have to find it.

After modeling solving a few algebraic expressions, have students work in their partner groups and take turns answering each question. I will come back to these questions as an assigned "I wonder warm-up" within the next few days.

Read and write an algebraic expression containing a variable

For students who struggle with the clue words, allow them to sit directly in front of the chart paper you created covering the operations and their clue words. After 3 minutes they share their thinking with a neighbor, and we have a few share out to the group.

If students make a mistake and learn from it, we share this too. For example, the word sum indicates to add. Students should know basic clue words for different operations, such as sum, difference, quotient, product, etc. The Hook - Students love a competition. What activities or exercises will students complete to reinforce the concepts and skills developed in the lesson?

I want my students to know that hard math is fun math. Susan has c number of cats. This is a tough code to crack. Volusia Is this Resource freely Available? This resource requires special permission and only certain users have access to it at this time.

What is the order used to solve multi-step problems? What is a code? Have them copy the expressions from their summative assessment onto a piece of paper, place an equals sign at the end of each expression, assign each one a value, and then solve for the variable.

Evaluating Expressions

What prior knowledge should students have for this lesson? You and your partners should be talking about the clues that you can find, before you write the algebraic expression.Plan your lesson in Math and Algebra with helpful tips from teachers like you.

SWBAT evaluate expressions using substitution. Lesson: Evaluating expressions means we can find a value for the expression if we are given a value for the variable.

This lesson uses students' prior knowledge of operational clue words and applies it to translating written phrases into algebraic expressions and vice versa, as well as analyzing word problems for key clue words and writing the representative expression.

This lesson is part of laying the foundation for algebraic thinking, including an understanding that cracking the code can be fun!
