Aims and objectives
This is a set of timed activities devised to place learning into
a real-life context. Students will be using their mental arithmetic
skills to work with money and time problems.
Previous knowledge
Students should have a basic understanding of problem solving using time and
money, including percentages, but for each section there are substantial revision
activities which take the user back to basics.
In the classroom
It’s a Saturday, it’s 9.00 am and you've just got up – time
to start shopping! You have £50 to spend on some new trainers
and you’ve got just 8 hours in which to sort out the bus
timetables, get to town, pay for your bus fares, buy your trainers
and get back home.
This is a set of linked resources which take the pupil through
a variety of problem solving activities placed in a real-life context.
The key activities are calculating the difference between times
using timetables, subtraction using money and calculating percentages
and discounts.
The challenge uses a speeded up virtual clock so that the maximum
'real' time allowable to complete the activity is 15 minutes. At
the end of the challenge pupils receive full feedback on their
results. The timetables, sums of money used and costs/discounts
for the trainers are randomised throughout the activity.
Throughout the challenge there are extremely detailed interactive
help sections which the pupil can call up if they feel they need
some support. These sections will automatically open if the pupil
appears to be struggling. Of course, the pressure is still on because
while the pupil works through the help, the clock is still ticking!
The activities themselves contain support materials which help students understand and practice the
concepts involved in the challenge.
