Get ahead by making the link between minutes past the hour and the five times table. The clock is a fantastic link between these two, and as you are rarely out of sight of one, there is always help at hand (excuse the pun!).
The "1"on the clock face represents 5 minutes past the hour
Also 1 x 5 = 5
The "2" on the clock face represents 10 minutes past the hour
Also 2 x 5 = 10
It would be worth pointing out that the "3" on the clock face represents 15 minutes past (or "quarter past") and 15 is a quarter of 60. Equally 30 is half of 60, for half past the hour.
Skipping around the clock face saying "5, 10, 15, 20 ..." is great reinforcement for multiplying by 5 and telling the time
An understanding that the gap between each number marked on the clock face represents "5" will helps with telling the time:
For the 24 hour clock the time could end in 25, 45 or 50 (all multiples in the 5 times table)
Alternatively "5 to" and "10 to" require an appreciation of the 5 minute gap between each number.
If you have a clock that would enjoy being decorated as shown in this picture, this one is sporting Removable Times Tables Wall Stickers from Kippson which you can buy here.
Alternatively, if you do not have an analogue clock displayed somewhere usefully prominent, you can always draw one, and even stick it on the fridge - perhaps with some numbered magnets around the outside?
It is a great way to maths maths more visible and give you a point of reference when trying to think through an answer.
