About this sheet
Word problems hide a number sentence inside a short story, and children often freeze because they do not know which operation the story wants. Certain words come up again and again: total and in all for adding, fewer and left for subtracting, groups of and each for multiplying, share equally and per for dividing. This poster lists those words beside each operation so a child has somewhere to start. It is a set of hints, not a set of rules, and the poster should be used that way. A problem that says Maya has 3 more than Sam can still need subtracting. The best habit is to read the whole problem, picture it, and only then choose the operation.
Grades: 1 to 5.
How to use it
- Review the four rows with the class and add the words your children actually meet in their own word problems.
- Print and post the poster beside the problem-solving corner, with a line on the board that says the story decides.
- Read a problem aloud, underline the clue words together, then test them: does the picture in your head match the operation?
Five ideas for class
- Collect trick problems where a clue word misleads, such as five more than a number being the answer when you are told the total, and add them to a class list.
- Have partners act out a problem with counters before choosing an operation, so the story is understood without relying on a keyword.
- Ask children to draw a bar or a picture for each problem first, then glance at the poster to check that their drawing agrees with the words.
- Cut a page of problems into strips, and let teams sort them under the four headings, then argue about any that fit under two.
- Invite the class to write a story problem for each row, using the clue words honestly, and swap them with another table.

Questions
Are keywords a bad way to teach word problems?
Used alone, yes, because the same word can point two ways. As a first hint to check against the whole story, they help many children find a way in.
Can I add words in another language?
Yes. Type them into the lines. Many families like to see the clue words in the language spoken at home, next to the English ones.
Why is half under dividing?
Taking half is splitting into two equal parts. Move it, or add halves under multiplying if your class thinks of one half of a number as one half times it.
How do I save it as a PDF?
Choose Print, then pick “Save as PDF” as the printer. Only the sheet prints: the page around it is hidden. You can also save a sheet as a PNG image under the preview.
Can I print it in black and white?
Yes. Switch to Black and white beside the sheet: fills turn white and lines turn black, so it saves ink and photocopies cleanly.
Is what I type saved or sent anywhere?
