Vocabulary Teacher Resources

Read for Understanding:

Read problems slowly. Stop at each punctuation

mark to identify key words that indicate

operations.

Define a Variable:

Identify the missing quantity in an equation.

Before writing and solving the equation, choose a

variable and state what the variable represents.

Be sure to include labels or units of measure.

Solve and Check:

Plug the solution back into the equation and

check the accuracy. Does the answer make sense

with the question? Is the answer reasonable?

Considerations:

When setting up word problems as equations,

encourage students to read the problem slowly and

more than once. Students should focus on the verbs

or action in the sentences to help them determine the

operation. Some problems will require students to

solve for a variable, but that is not the final answer.

There may be multiple answers to an equation and all

answers must be given to have a solution. Request

that students use substitution to plug answers back

into the equation to check work. Encourage pictures

or diagrams to help organize information.

*Reminder: All forms of the word “is” indicate the

equal sign in a word problem (is, was, will be).

Steps:

1. Read and pause at the punctuation to
   record thinking.


2. Circle keywords that indicate the
   operation to use.


3. Underline the question. This is the
   missing variable.


4. Write the equation and solve.


5. Plug the solution into the equation.


6. Check for reasonableness.
