Proven strategies for clock faces, elapsed time, and transport timetables.
Reading Analogue Clock Hands
Read the long minute hand first: each clock number represents 5 minutes (e.g. hand on 7 = 7 × 5 = 35 mins). Next, check the short hour hand: if it is past 8 but hasn't reached 9, the hour is 8.
Example: 8:35 or "twenty-five to nine"Converting 12-Hour ↔ 24-Hour Time
For PM times, add 12 to the hour digits (4:15 pm → 4 + 12 = 16:15). To convert 24-hour back to 12-hour, if the hour is 13 or greater, subtract 12 and write "pm" (19:40 → 19 − 12 = 7:40 pm).
Midnight Trap: 12:00 am is 00:00, NOT 24:00Calculating Elapsed Time (The Jump Method)
Never subtract times vertically! Draw a number line with 3 simple jumps: Jump 1 to next whole hour (09:35 to 10:00 = +25m), Jump 2 in whole hours (10:00 to 13:00 = +3h), Jump 3 to final minutes (13:00 to 13:18 = +18m). Add jumps: 3h + 25m + 18m = 3h 43m.
Key Strategy: Jump to the hour firstTimetable Detective Problems
Public transport timetables read top-to-bottom (each column is a single journey). To find journey duration, locate departure station and arrival station in the same column, then use the Jump Method. For frequency, find the difference between consecutive departures.
