Are scholars correctly identifying the variable? After five minutes in the corner generating a list of words, each person brings their list back to their team to share the words. Students will work with a partner to complete against an opponent pair. Using the word lists and discussion, help students complete the 12 items below the lists on the journal page.
I then cold call on students to read the verbal expressions for Problems 26 - I want to give students practice with writing all types of expressions.
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. Assign any additional practice or application from text as needed.
Have students list their words on the journal page attached. I am looking for: I want to discuss that addition is commutative, and either expression will work.
What amount are you starting with? 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. How did you know what the variable was?
Some students will not read carefully, and will not use a to represent their age now. Will the expression have the same answer if you changed the order of the terms?
Each player takes a turn showing either side of a card they choose. Each group is given a set of Expressions Cards attached.
Are scholars correctly identifying the constant? I ask which expression is correct for Problem 1: For example the second expression could be read: Then, have students work together with their team to think of different ways to write and read the expression, 3b.
Disagreements or uncertainty can be decided by the teacher. The cards are shuffled and divided so that each pair gets half the cards- each person taking 6 cards. We need to be able to read math expressions using words, and we need to be able to write math expressions when we read the words.
Their opponents must tell what they think is on the other side of the card. What does the constant represent given the context of the problem? Are scholars correctly translating the verbal expression into numerical form?
In this set, there are problems that ask students to write numeric expressions without variables. Practice using a game Copy the attached Expressions Cards as a two-sided card stock page. What does this coefficient mean? What words indicate operations?
Problem 23 will confuse some students, because the expression will be 6 - As they work, I circulate around the classroom and check in with each group.
What does the variable represent given the context of the problem? How did you know what the constant was?Writing Variables Expressions Worksheets.
This Algebra 1 - Basics Worksheet will create word problems for the students to translate into an algebraic statement. Type of Problems. Easy (One and Two Terms with Single Variable) Medium (Two Terms with Single Variable) Hard (Two and Three Terms with Two Variables).

Apr 30, · How to Write an Algebraic Expression An algebraic expression is a mathematical calculation built from numerical constants, variables, and mathematical operations.
Many well-known theorems state the equivalence of two expressions, but an expression itself doesn't represent an equality as an expression is only one half of an 22%(9). 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.
