Enough Information? Word-Problem Reasoning | Ages 8–10 | 6 Worksheets + Explained Keys

A correct calculation can answer the wrong question. These six worksheets ask children to test which facts determine an answer, explain missing information with two valid examples, and justify a reliable question plan.

For confident readers and calculators aged 8-10; select the optional follow-ups by readiness. Requires addition/subtraction to 100, small multiplication facts and equal sharing. Read-aloud and spoken explanations are possible. A focused reasoning sequence, not a full word-problem course or SATs test.

A-D: one story with two questions; enough or missing information; test extra clues separately; check an answer and change a problem. Optional E/F: contrast a helpful single result with a question that always helps, then prove or disprove fixed two-question plans. Four labelled bags with 1-10 whole marbles form the invented E/F model; direct target questions are excluded.
