Math
Strategy: Coding Word Problems
Appropriate Grade Level: 1-12
Procedures/Steps:
1. Start with a mathematical word problem.
2. Review the steps to solving a word problem.
3. Specifically address the step in solving word
problems that deals with finding the information
in the problem.

6.
Read the problem carefully.
Look for the question or key words.
Find the information or numbers.
Make a plan.
Solve the problem.
Check your answer.
4. Have students use writing tools (pencils, highlighters, pens, crayons, etc.) to “code”
the story problem in the following manner:
Example:
Tommy has 8 marbles
in his pocket. While
playing marbles at
recess he wins 9 more
marbles. How many
marbles does Tommy
have in all?
- Use a colored pencil to underline the information
(numbers) in the problem.
- Use a highlighter to highlight the key words or
question.
- Use a black crayon or marker to blacken
distracters (unimportant wording).
- Use a pencil to circle the word in the question that
will go with the answer.
5. Have students use the items they “coded” to complete the rest of the steps to solve the
word problem.
Comments and/or tips:
- This strategy should be taught along with or closely after a lesson on the steps for
solving word problems.
- Simplify this for younger students or students who struggle with math by using fewer
utensils.
