I want students to share that a and b have the same answer as well as g and h. We go through the table and I ask students to identify which operation matches which group of expressions. 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.
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 then show students the different ways to represent those expressions parentheses, dot, fraction bar, etc. We could use the division symbol, or we could use the fraction bar. When most students are finished I have students share out different ways to represent each problem.
From there I have them identify the variable and numbers involved. For this lesson I want students to practice change expressions from word form to numerical form before we start working with algebraic expressions.
Using Cards in Class Practice 2. Students have to copy each example in the appropriate column, expression or equation, and then identify coefficients, constants, and variables. How can write an expression to represent them?
I read the example and I have students volunteer to share two ways that I could model the problem with my cards.
I write example 1 and 2 in algebraic form. I want to address those misconceptions in the do now before moving on to algebraic expressions and equations. I ask students to share with their partner which number sentences result in the same answer.
Eric has 12 dollars less than her. I am looking in particular at 3 and 4 to see if they are able to represent them correctly. I encourage students to visualize what is going on.
After a minute of sharing, I ask students to share out. To check the do now, display answers from 1 a — h. As students are working I walk around and monitor student progress. As students are working I am walking around and monitoring student progress.
You subtract 12 dollars from your amount of money. How much money does Eric have? Often, I create do nows that have problems that connect to the task that students will be working on that day.
Then students compare their work. Make sense of problems and persevere in solving them as well as MP 4: Here students are using MP2: How many dollars do you have now? We will address any questions or misunderstandings. They get to work quickly on the problems.
Construct viable arguments and critique the reasoning of others. 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 am looking at particularly at and Variable and Verbal Expressions Date_____ Period____ Write each as an algebraic expression.
1) the difference of 10 and 5 10 − 5 2) the quotient of 14 and 7 14 7 3) u decreased by 17 u − 17 4) half of 14 14 2 5) x increased by 6 x + 6 6. Create free worksheets for writing simple expressions with variables (pre-algebra / algebra 1 / gradeseither as PDF or html files.
