Choose the algebraic expression that correctly represents the phrase provided. Write each phrase as a mathematical expression. Some students will not read carefully, and will not use a to represent their age now.
In the next few examples, we will be working solely with algebraic expressions. Will the expression have the same answer if you changed the order of the terms? I am looking for: In this set, there are problems that ask students to write numeric expressions without variables.
Jensen likes to divide her class into groups of 2. What does this coefficient mean? Problem 23 will confuse some students, because the expression will be 6 - The value of this number can change.
I then cold call on students to read the verbal expressions for Problems 26 - If x is 6, then the expression has a value of I want to discuss that addition is commutative, and either expression will work.
As they work, I circulate around the classroom and check in with each group. If I see things like 12 - 6 for Problem 4 or 10 for Problem 5, then I know that students are not thinking about using an unknown and are using their actual ages.
As they are working, I am looking specifically at problems 4 - 7. Let g represent the number of groups in Ms.
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 does the constant represent given the context of the problem?
Are scholars correctly translating the verbal expression into numerical form? If you make a mistake, choose a different button. Let x represent the number of hours the electrician works in one day.
How did you know what operation to use? How did you know what the constant was? What amount are you starting with? Write an algebraic expression to represent his earnings for one day.In this lesson you will learn how to read and write algebraic expressions by using variables.
