What time will it be in thirty minutes? Scholars use three digital clocks to answer nine questions which require they add and subtract minutes from a given time. Learners record what time it will be in a specific number of minutes or hours and do the same for what time it was. All times here end in either five or zero. Consider asking learners to do this with their own lives, prompting them to consider the time they leave for school: What time was it two hours before then? Two hours later?
