What this worksheet covers
There are twenty story problems here — one page to work, one page of answers to check against — and Sets B and C repeat the layout with different numbers. The problems are written as situations that have to be translated before they can be calculated and answers carry units, and a number without its unit is only half an answer. Problems 7 and 14, for instance, are "Emma begins piano practice at 5:15 PM and plays for 30…" and "A library story time begins at 2:30 PM and lasts 40…". It is written against Common Core 3.MD.1 — Measurement & Data, grade 3.
Skills practiced
The grade 3 time and money sequence covers reading a clock to the minute, elapsed time in minutes, making change, and adding money; this page sits inside it. What a student is asked to do here is telling Time & Adding Time Intervals. Concretely, the sheet tests whether a student can read a situation and choose an operation before computing. Eighteen different answers appear across the twenty problems, so a student cannot copy one result down the page.
About the word problems format
The 20 story problems each get a full line and an answer rule; problem 7, "Emma begins piano practice at 5:15 PM and plays for 30…" is one of them. Practice schedules, lunch money and movie times are the situations time and money were taught for.
Set A, Set B and Set C
Set A is the original sheet; Sets B and C redraw each problem with the same shape and recomputed answers. Where Set A's problem 11 is "Recess begins at 10:05 AM and lasts 15 minutes. What time…", Set B's is "Felix starts reading at 10:40 AM. Felix reads for 55…".

How to use this worksheet
Work the twenty problems straight through, then check against the key together rather than handing it back marked; asking a grade 3 student to find their own time and money error teaches more than seeing it circled. Ask the student to re-work one missed time and money problem from scratch on Set B rather than correcting it in place; the second attempt shows whether the method changed.
One mistake to watch for
Elapsed time is added as if minutes went to 100. Problem 9 on this grade 3 word problems page, "A science experiment starts at 9:10 AM and takes 55…", is where to look for it.
Decimal place value is being applied to a base-60 system.
Count to the next hour first, then add what remains.
