What do these problems look like?

Five short stories per sheet: a bus leaves at one time and arrives at another, and your child finds the time in between. Each problem has room for the number line and an answer line for hours and minutes.

My child keeps subtracting the times and getting odd answers. What helps?

Clock arithmetic isn't base ten, so column subtraction misfires. Teach the count-up instead: jump from the start to the next o'clock, then to the end, and add the jumps. The answer key shows those same jumps.

How to teach this

Before any counting, have your child read the story twice and underline the two times. Then sketch a quick number line in the work box and count up in two jumps: start to the next o'clock, then on to the end. Writing both jumps down (30, then 45) turns adding them into the easy part. A 75-minute answer is fine at first; converting to 1 h 15 min can wait a beat.

Watch for: Kids subtract the times like plain numbers, so 4:15 minus 3:45 comes out as 70 minutes. An hour has 60 minutes, not 100. Count up on a number line instead: 15 minutes reaches 4:00, then 15 more. Kids compute before checking what's missing, so a find-the-end-time story gets an elapsed-time answer. Have them say the missing piece first: the start, the end, or the time in between. Kids lose a.m. and p.m. when a story crosses noon. Make 12:00 a landmark: count up to noon, say 'now it's p.m.', and keep going.
