______________________________________________________________________

Verify: Verify your plan. Write an estimate. ____________________

Carry out your plan.

Examine: Examine the results. Is this answer reasonable? _____

Is this answer accurate? _____

Does this answer make sense? ____

Write your answer as a complete thought.

Excerpt from

Step 1: For S (Study the Problem), tell students that most of the time it is best to say “This problem is asking me to find,” and continue with the word ‘‘the’’. Underline the question in the problem and fill in the blank in the S step.

Step 2: For O (Organize the Facts), tell students that you are going to re-read the problem, and you want them to say “stop” or “fact” every time they

hear a fact. You may need to remind them that a fact is a true statement.

You might also want to tell them that facts are also numbers and that

more than one fact can be in a sentence. If students haven’t said “fact”

by the time you get to a period, they should say “fact” at the end of the

sentence.

• Every time students say “fact” or “stop,” place a vertical line between

the two facts.

• Next, go back to each fact and ask students if the fact is necessary to

know in order to find what students are being asked to find in S. If it

is not needed, cross it out. If it is, write it down under O.

Step 3: For L (Line Up a Plan), explain that you will be writing a plan in words, with no numbers. Tell students that the reason they write the plan in

words with no numbers is so that if they come across the same problem

later, and the numbers are changed, they can still use the plan.

• Ask students what operations they think should be used to solve

Problem 1.

• As you write the plan, make sure that it includes all the written facts

from the O step. While writing plans, some students will have a hard

time not using numbers. If they give you a number, ask them what

the number stands for.

• Also remember that there is more than one correct plan, so if students

come up with different plans, let them share them. As long as the plan

makes sense mathematically, it is correct.

Step 4: For V (Verify Your Plan with Action), first ask students what they think a good estimate would be. Remind students that they do not always have to round and do the work to get an estimate. They can say things like,

“I think it will be less than $20, because it is 11 miles plus two more

dollars.” Then have them follow the plan exactly as written in L.

Step 5: For the last step, E (Examine Your Results), ask students the three

questions:

• Does your answer make sense? (Compare your answer to the question.)

Have students go back to S to be sure that their answer does answer

the correct question.

• Is your answer reasonable? (Compare your answer to the estimate.)

Have students go back to V and check their estimates.

• Is your answer accurate? (Check your work.) Tell students to go back

to V and redo the math—alone or with a partner. Students may redo

the problem with or without a calculator. You want them to actually

redo the work, not just look at it.

Have students write the answer in a complete sentence. Tell students to

go back to S and re-read what the problem was asking them to fi nd. This

will help them to write the answer in a complete sentence.
