# 6th grade math writing algebraic expressions

Here students are using MP3: Construct viable arguments and critique the reasoning of others. I want to discuss that addition is commutative, and either expression will work. Students do not learn to perform integer operations in 6th grade, but students will be suspicious that something is wrong because of the order of their terms. What is happening to that value? Students take turns creating algebraic expressions or equations with cards out of view of the other student and reading it aloud to the partner. I encourage students to visualize what is going on. We will address any questions or misunderstandings. As students are working I am walking around and monitoring student progress. I re-read the phrase and ask where the student thinks each value belongs. I write example 1 and 2 in algebraic form. How did you know what the constant was? Translating Words Into Algebraic Expressions 10 minutes I tell students that in algebra they are going to be using variables to represent a situation.

I read the example and I have students volunteer to share two ways that I could model the problem with my cards. As students are working I walk around and monitor student progress. Then students compare their work. We will address any questions or misunderstandings. So the product of negative 1 and x, that's just going to be negative 1x, which is the same thing as negative x. I re-read the phrase and ask where the student thinks each value belongs. How many dollars do you have now? So that's going to be plus 1. What does the constant represent given the context of the problem? Or we can just write this-- this is the exact same thing as negative 6 minus x. Unit 6. Now this one. I ask students to share out one thing that they wrote down on their do now that will help make today a productive math class.
