					Time, Speed and the Metric
         System
                   Time
We need to know times so we can organise and
manage our daily activities. If we didn’t know
times it would be very hard to plan activities
with our friends, we would be late for meetings
and events and we would not know when to
look at our favourite TV. programmes
  Sometimes when we get distracted we lose
track of time. If we didn’t know times this would
happen all the time.
Measurement: hours and minutes and seconds
          The Metric System
The metric system is the most basic form of
measurement which is commonly used all over
the world. It is used for trade with other
countries or even just travelling and
communicating in foreign countries

Measurement: metres and
kilometres.
                      Speed
It is very important to know speed and know how to
calculate speed. We need to know how fast or slow we
are going in a car otherwise there would be an awful lot
more car accidents.
We also need to be able to calculate speed too for
everyday situations such as going to a meeting.
If you need to be at a meeting in 2 hours and the meeting
is 50 miles away,. you need to know what speed to drive
at if you want to reach the meeting in time. Luckily, we
have dads silly triangle to help us do this
Measurement: m/s km/hr
