What's on this sheet

Adding an interval to a time is easy until the minutes pass sixty, and that carry is the whole point. 3:15 plus thirty minutes is 3:45 and teaches little; 3:45 plus thirty is where an hour carries and base sixty stops being a detail. Questions that cross the hour and questions that do not are drawn as separate groups, so a page never fills with the comfortable kind.

Why this sheet works

Intervals move in five-minute steps a child can count round the dial — five, ten, twenty, forty-five — rather than a thirty-seven-minute jump that is only arithmetic wearing a clock. Counting up to the next whole hour first, then adding the rest, is the method the page is built to reward.
