Maths Challenges

This week is all about time! The best way to learn time is to bring it into every day activities. Look at the clock, what time is your lunch? Bed time? How many clocks are in your house? Can you convert between the analogue and digital clocks in your house?

Challenge one:

LO: To recognise how many seconds there are in a minute.

Starter: Times tables- practise your 7 and 9 times tables by drawing a hopscotch grid on the floor with one digit numbers inside as you jump each one recite the multiplication fact.

Main: Ask somebody in your house to start a one minute timer. Close your eyes. When you think one minute has passed say stop. How close were you? How many seconds are there in a minute?

There are 60 seconds in one minute- so how many in two minutes? How many in 5 minutes? To multiply by sixty, it is easiest to first multiply by six and then multiply your answer by ten.

Lets practise converting:  If It look me 3 minutes and 69 seconds. How could I convert this? Covert the three minutes first, then add on the 69 seconds.

Activity:

Time yourselves doing different activities. E.g. How long does it take you to do 50 star jumps? If it takes 5 minutes 43 seconds what is this just in seconds? (convert the first minutes 5x60= 300 then add on the 43 seconds = 343 seconds). Complete with a range of different activities.

Challenge two:

LO: To recognise the relationships between units of time.

Remember:

There are 7 days in one week.

60 seconds in one minute.

12 months in one year.

Starter: Times tables- practise your 7 and 9 times tables as you complete star jumps outside.

Main: Convert between different units of measurements E.g. how many months are there in 8 years? (12 x8). You can make up your own questions for this- or you can complete the sheet attached.

Challenge three:

LO: To tell the time to the five minute interval on an analogue clock

Starter: Times tables- practise your 7 and 9 times tables.

Main: This should be a recap lesson. Can you read the time to the five minute interval on an analogue clock? Practise on your clocks at home- then you could look at the worksheets below. No need to print.

## Telling the Time - 5 min intervals

Challenge four:

LO: To tell the time to the nearest minute

Starter: Times tables- practise your 7 and 9 times tables.

Main:  Can you read the time to the nearest  minute on an analogue clock? Practise on your clocks at home- then you could create your own snap cards- or use the ones below to help you practise reading an analogue clock.
