As they work, I circulate around the classroom and check in with each group. I am looking for: Are scholars correctly identifying the variable?

Students walk into class and pick up the packet for the day.

They get to work quickly on the problems. Often, I create do nows that have problems that connect to the task that students will be working on that day.

For this lesson I want students to practice change expressions from word form to numerical form before we start working with algebraic expressions.

To check the do now, display answers from 1 a — h. I ask students to share with their partner which number sentences result in the same answer. After a minute of sharing, I ask students to share out.

I want students to share that a and b have the same answer as well as g and h. I call on students to share their mathematical thinking. In the past I have found that many students mistakenly think that problems like and as well as 2 divided by 1 and 1 divided by 2 are equivalent.

I want to address those misconceptions in the do now before moving on to algebraic expressions and equations. 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.

I find that students enjoy sharing out these goals — it is a way for them to be held accountable by their teacher and peers. I tell students that they will be connecting their knowledge operations to algebraic expressions and equations.

I call on students to read the vocabulary words and the examples. Students have to copy each example in the appropriate column, expression or equation, and then identify coefficients, constants, and variables. I am walking around and making sure students are on task and that they are using their notes to correctly identify the vocabulary words.

We will address any questions or misunderstandings. Here students are using MP3: Construct viable arguments and critique the reasoning of others. Translating Words Into Algebraic Expressions 10 minutes I tell students that in algebra they are going to be using variables to represent a situation.

Before we model situations using variables, expressions, and equations we need to be able to translate expressions and equations between word form and algebraic form. I write example 1 and 2 in algebraic form.

We go through the table and I ask students to identify which operation matches which group of expressions. I then show students the different ways to represent those expressions parentheses, dot, fraction bar, etc.

I stress that the order of the variable and the number matter for division and subtraction. I mention the do now problems where we showed that the quotient of two and one is different than the quotient of one and two. How can write an expression to represent them?

Many students struggle that these phrases are represented by n and not 12 — n, the way that the values appear in the phrase. Palmer has n dollars. Eric has 12 dollars less than her. How much money does Eric have? You subtract 12 dollars from your amount of money.

How many dollars do you have now? I encourage students to visualize what is going on. What value are you starting with? What is happening to that value? Here students are using MP2: Reason abstractly and quantitatively.

I encourage them to look back to their notes on the previous page if they get stuck.My daughter is in 10th grade and son is in 7th grade. I used to spend hours teaching them arithmetic, equations and algebraic expressions.

Then I bought this software. Create free worksheets for writing simple expressions with variables (pre-algebra / algebra 1 / grades , either as PDF or html files.

The problems give the student the expression in words, such as the quotient of 7t and 5, the difference of x and 8, divided by 2, or the quantity 8 plus 2t, cubed, and ask the student to write a.
