The usual Primary 1 error is not reading the hands but reading a minute hand on the 6 as six minutes. On the 6 it is thirty minutes, because each big step is five minutes, and that step has to be counted out loud.

Objectives — The pupil can: (1) say that the short hand tells the hour and the long hand tells the minutes; (2) read whole hours and half hours from the position of both hands; (3) say that one hour is 60 minutes and half an hour is 30 minutes; (4) count forward from one time and say what time it will be after a given number of minutes.

01 Prerequisites (3-minute check)

If any of these fails, fix it before the lesson starts.

Skill	Quick check	Pass mark
Counting to 60	counts from 1 to 60	no gaps in the sequence
Counting in fives	says 5, 10, 15 up to 60	both directions
Recognising a clock	points to the two hands	says which is short and which is long

02 Lesson flow (40 minutes)

Time	Stage	Tutor does	Student does
0–5 min	Diagnose	holds up a real clock, asks which hand is which	points and describes them
5–15 min	Two hands, two jobs	moves the hands, says whole and half hours	reads 3 o clock and half past 3
15–25 min	One big step is five minutes	counts 5, 10, 15 from the 12	counts to the minute hand
25–35 min	Counting forward for an interval	starts at 3:45 and counts 25 minutes	says 4:10
35–40 min	Exit check	three questions	all correct

03 Teaching script (read it out)

Scene 1: Act 1: Two hands, two jobs

Use a real clock with movable hands. Set it to 3 o clock and ask the time, then set half past 3. The pupil should say that the short hand has moved between the 3 and the 4, so it is half past three. Make the division of labour plain: the short hand tells when, the long hand tells how many minutes. Primary 1 pupils often look at only one hand.

Tutor line: “The short hand moves slowly and tells you the hour. The long hand moves quickly and tells you the minutes. Now tell me: where is the short hand, and where is the long one?”

Scene 2: Act 2: One big step is five minutes

The commonest misconception is reading a minute hand on the 6 as six minutes. Start at the 12 and count step by step: 12 is zero minutes, 1 is five, 2 is ten, 3 is fifteen, 6 is thirty. Write 5, 10, 15, 20 in a coloured pen beside the numbers and have the pupil count it, rather than telling the answer.

Tutor line: “The long hand on the 6 is not six minutes. Start at the 12, five minutes a step, and count up to the 6. How many is that?”

Scene 3: Act 3: Count forward, do not subtract

Ask: it is 3:45 now, what time will it be in 25 minutes? Subtracting confuses Primary 1 pupils. Count forward instead: from 45 minutes, five minutes takes you to 4 o clock, and there are 20 minutes left, so the answer is 4:20, which is the same method that turns 3:45 plus 15 minutes into exactly 4 o clock. Let the pupil walk a finger around the clock face, one step at a time, and stop after 25 minutes.

Tutor line: “Do not subtract. Start at 45 minutes and step forward one step at a time until you have counted 25 minutes, then see where you stop.”

04 Question types and worked steps

Type	Example	Steps
Whole hours: minute hand on the 12	read the short hand, say the hour	3 o clock
Half hours: minute hand on the 6	short hand between two numbers, add half past	half past 3, which is 3:30
Adding minutes to a time	count forward one step at a time, stop when done	3:45 plus 25 minutes is 4:10
Finding how long something took	count forward from the earlier time to the later one	from 10:15 to 11 o clock is 45 minutes

Sanity check (teach this): Primary 1 reads whole hours, half hours and times in five-minute steps only. Reading every single minute, such as 7:23, and the 24-hour clock are not taught. Intervals are always counted forward, never subtracted. Answers are written as a time, not as a bare number.

05 Independent practice (3 questions)

Question	Answer	What to watch
The minute hand is on the 12 and the short hand on the 8: what time is it?	8 o clock	did the pupil check the short hand
The minute hand is on the 6 and the short hand is between the 6 and the 7: what time is it?	half past 6, which is 6:30	was the 6 read as six minutes
It is 3:45; what time is it 25 minutes later?	4:10	was the time counted forward
From 9:20 to 9:50, how many minutes pass?	30 minutes, half an hour	were the steps counted
It is 11:40; what time is it 25 minutes later?	12:05	was the crossing of 12 handled

06 Common mistakes and what to say

Mistake	Student writes	Say this
Reading the number the minute hand points at as minutes	the hand on the 6 read as six minutes	“Start at the 12, five minutes a step, and count up to the 6. How many is that?”
Writing 3:60	half past 3 followed by 3:60	“Sixty minutes is one whole hour, so it carries over to 4 o clock.”
Looking at one hand only	answering from the long hand alone	“The short hand tells the hour, the long hand the minutes. You need both.”
Subtracting to find an interval	45 minus 25 written as 3:20	“Count forward instead of subtracting. When 45 reaches 60 the hour moves on.”

Primary 1 addition within 20, counting on — section 3, question steps

08 Exit check (last 5 minutes)

Question	Answer	Decision
The minute hand is on the 3: how many minutes is that?	15 minutes	if wrong: reteach the five-minute step
What time is it half an hour after 6:30?	7 o clock	if wrong: reteach carrying 60 minutes
From 2:10 to 3 o clock, how many minutes pass?	50 minutes	if wrong: reteach counting forward

09 Tutor FAQ

A real clock or a worksheet?

A real clock first, for at least three lessons. Primary 1 pupils cannot yet rotate hands on paper; a clock they can hold can be turned, can be wrong, and can be corrected.

Should digital clocks be taught?

Compare one after reading an analogue clock, for example 7:00 against seven o clock. But assessment works from the analogue face; the digital display is only a check.

The pupil can read a clock but cannot work out how long something took. Why?

Reading a clock is recognising a position, while an interval is counting a distance. They are different skills, so practise counting forward with a finger actually moving round the face.
