References provide support for statements and add credibility to writing. The rules for what needs a citation are an academic tradition, but are rarely stated explicitly:
As they work, I circulate around the classroom and check in with each group. I am looking for: Are scholars correctly identifying the variable? Are scholars correctly identifying the constant?
Are scholars correctly translating the verbal expression into numerical form? How did you know what the variable was? How did you know what the constant was? What amount are you starting with? Will the expression have the same answer if you changed the order of the terms?
How did you know what operation to use? What does this coefficient mean? What does the variable represent given the context of the problem? What does the constant represent given the context of the problem?
I also ask students if, in Problem 1C, '9 minus a number' would produce the same algebraic expression as '9 less than a number. As they are working, I am looking specifically at problems 4 - 7.
Some students will not read carefully, and will not use a to represent their age now. 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.
In this set, there are problems that ask students to write numeric expressions without variables. I want to give students practice with writing all types of expressions. Problem 23 will confuse some students, because the expression will be 6 - 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.
I ask which expression is correct for Problem 1: I want to discuss that addition is commutative, and either expression will work. I then cold call on students to read the verbal expressions for Problems 26 - can use algebraic expressions to represent words or phrases.
Just as you can write addition and subtraction expressions from words or phrases, you can also write multiplication and division expressions. Once again, you can use key words to help you with this.
Writing Expressions and Equations 3 times a number; t # # # 3 t. In Example 2, each algebraic expression consisted of one number, one operation and one variable. Let's look at an example in which the expression consists of more than one number and/or operation.
Example 3: Write each phrase as an algebraic expression using the variable n. DESCRIPTION OF COMPUTERIZED TESTING. Back to top.
