Converting times between 12-hour (am/pm) and 24-hour formats in both directions.
Where your child meets this in real life: Converting between formats when planning journeys or scheduling events
Each SEAG paper has 28 maths questions. Questions 29 to 50 are multiple choice with five possible answers, and questions 51 to 56 need a short written answer. With 56 questions in 60 minutes across English and maths, that is about a minute per question.
SEAGReady breaks convert between time formats into 3 steps, taught in order so each skill builds on the last.
Convert times between 1am-11:59am and 01:00-11:59 in both directions
Convert times between 1pm-11:59pm and 13:00-23:59 in both directions using add/subtract 12 rule
Convert times involving 12am (midnight hour) and 12pm (noon hour) correctly, recognising exceptions to the add 12 rule
Try three free questions from our convert between time formats course. They start easy and get harder, so you can see where your child's confidence runs out. If they manage the last one without a hint, this topic is probably secure. If not, the steps above show where to start.
Josh's swimming lesson time is shown on a 12-hour display. What time should he look for on a 24-hour booking system?
The visitor centre closing time is shown. What time is this in 12-hour format?
Which of these statements about noon and midnight is TRUE?
This is the exact interactive worked example your child sees in SEAGReady. Step through it and watch the method build up.
Isla has a dentist appointment at 9:15 am. The receptionist writes it down in 24-hour time.
What time does the receptionist write?
9:15 am to 24-hour
The time says 'am' so it's morning
Step 1 of 4
Isla has a dentist appointment at 9:15 am. The receptionist writes it down in 24-hour time.
What time does the receptionist write?
The receptionist writes 09:15.
The key insight: Morning times just need a leading zero - no maths needed!
Common mix-up: 9:15 am = 9:15 (no leading zero). 24-hour time always uses two digits for hours: 01, 02, 03... up to 23.
These are the misconceptions we see most often in convert between time formats, including the ones our practice questions are specifically designed to catch.
