Elapsed Time Game
Free elapsed time game: jump along a time line from start to end, add up the hours and minutes, or move a real clock forward or back by a given time.
Every question shows real analog clocks and an open time line. How Much Time? gives a start and an end: jump with +1 h, +30 min, +15 min, +5 min and +1 min chips until you land on the end, then add up your jumps. What Time Will It Be? and When Did It Start? give one clock and a duration: jump forward or back and watch the clock cross the hour. Four levels move from half hours to single minutes, always on one day.
Jump from the start to the end, then add up your jumps.
Not a test — nothing is saved after you leave.

Jump along the time line from one clock to the other, then add up the hours and minutes.
How to use the elapsed time game
- 1Choose How Much Time?, What Time Will It Be?, When Did It Start?, or Mixed, and a level.
- 2Tap the jump chips to move along the time line; the clock and the time line show every jump, and you can take a jump back.
- 3In How Much Time?, land exactly on the end time, then type the hours and minutes your jumps add up to.
- 4In the other modes, use up the given duration with jumps, then check — the feedback shows one clean path to the hour and beyond.
When this is useful
Learning the jump strategy
Jump to the next hour, count whole hours, add the rest — the method taught in grades 2–4 for elapsed time, made visible on a line.
Crossing the hour and crossing noon
Start and end times are chosen so most questions cross an hour boundary; Level 4 adds 12:00 crossings written with AM and PM.
Schedules and timetables
What Time Will It Be? is the bus-leaves-at question; When Did It Start? is the working-backwards one.
Differentiated practice
Half hours for early learners, quarter hours and five-minute steps for most of the class, single minutes for students who want a challenge.
Projector-friendly
Two large clocks and big chips suit a whole-class round with students calling out the next jump.
Examples to try
How Much Time?, Level 3
9:40 AM to 11:15 AM: +20 min to 10:00, +1 h to 11:00, +15 min to 11:15 — 1 hour 35 minutes.
What Time Will It Be?, Level 2
Starts at 2:45 PM and lasts 1 hour 30 minutes: +1 h, +15 min, +15 min — 4:15 PM.
When Did It Start?, Level 1
Ends at 7:30 PM after 2 hours: two jumps back of 1 hour — 5:30 PM.
Level 4
Durations like 1 hour 47 minutes, so the +1 min chip is needed and the hour hand moves between numbers.
Tips for better results
Aim for the next whole hour first
The feedback always shows this path; students who copy it stop making the 60-minute regrouping error.
Fewer jumps is a nice goal, not a rule
Any set of jumps that lands on the end is right; efficiency comes with practice.
Pair it with the telling-time game
If reading the clock is still shaky, run Telling Time first; this game assumes the time can be read.
Mixed mode for review
Once each mode is familiar, Mixed asks all three questions in one round.
How the elapsed time game works
Every item is a start time, a duration and an end time on the same day, chosen so the start lands on the level's step (30, 15, 5 or 1 minutes) and the end never passes 10 PM.
The time line is an open number line: each chip adds its minutes, draws an arc, and moves both the pointer and the clock, so an hour crossing is visible rather than hidden in subtraction.
How Much Time? is marked right when the typed hours and minutes equal the real duration; the other two modes are marked right when the jumps use up exactly the given duration, so the clock shows the answer.

Frequently asked questions
Is this elapsed time game free?
Yes. No account, no limit on rounds, no ads. Nothing is saved after you leave the page.
What grades is it for?
Level 1 (half hours) suits grade 2; Levels 2 and 3 (quarter hours, five-minute steps) suit grades 3–4; Level 4 (single minutes) is a grade 4 challenge.
Does it use a 12-hour or 24-hour clock?
The English game uses a 12-hour clock with AM and PM, which is what US classrooms teach. Questions never cross midnight.
Why jump chips instead of typing the answer?
Jumping to the next hour and counting on is the strategy teachers want students to use; the chips make that strategy the way you play.
Can I take a jump back?
Yes. Undo removes the last jump, and the clock and the time line move back with it.
Can I play with a keyboard only?
Yes. The chips and buttons are ordinary buttons, and Enter checks a typed answer.
Does this use AI?
No. The game is plain time arithmetic running in your browser.
Is there a matching worksheet?
Yes — the Elapsed Time Worksheet Generator prints the same three question types with an answer key.
