Elapsed Time Problems

A generator of problems on how much time is left until a show starts. Each problem reads, for example, “It is exactly 14:35. Show starts at 16:10. Remaining” and the child fills in “1 hour and 35 minutes”. Times use the 24-hour clock and the show starts at most four hours later. Choose whether the times are whole hours, five-minute steps, any minute, or less than an hour apart.

On the website you place the problems on an open-answer sheet, for example a short test or a maths trail. They also go on cards with the problem on one part and the answer on the other. Every time you generate, you get new times.

It suits children from Year 4 (3rd grade) who can tell the time and are learning to calculate with hours and minutes.
