Word problems — Grade 3

A word problem is maths in a sentence. The numbers and the question are there — your job is to decide which operation to use.

The maths itself is the same as in the exercises. The hard part is the language.

A reliable plan

For any word problem, follow these steps:

  1. Read the whole problem. Don't grab numbers right away.
  2. Find the question ("what does it ask?").
  3. Pick numbers and what they mean.
  4. Decide the operation (add / subtract / multiply / divide).
  5. Compute.
  6. Check — does the answer make sense? Include the unit.

Operation keywords

Words don't decide the operation by themselves — but they're a hint:

OperationWords to look out for
Addaltogether, total, in all, more
Subtractleft, fewer, less, take away, difference
Multiplyeach, per, equal groups, rows of, times
Divideshare, equally, each child, per group, how many groups

Summary

  • Read first, decide second, compute last.
  • Words suggest the operation but don't always force it.
  • Always include the unit.
