Example
'Rain on the Roof' is a simulation of raindrops that have fallen on a roof (that has been divided into 16
square) in a 'snapshot' in time.

Example 2
'Number Guess Game'. The
input number is entered and the
reply from the program is a 'too
high' or 'too low'. You have 7
chances!
This is a good strategy and logic
game, compare the game with
the notion of folding a piece of
paper in half over and over again.
The 'lowest score' is kept in
memory space 'L'. When you exit
the game or turn the calculator
off the memory of 'L' is returned
to the original setting of 8. Happy
guessing!
Refer to the 'Programme Mode
Command List' for entering and
editing the program. (See index
for page reference)
This is a Poisson Distribution activity that lets the 'user' decide how
many raindrops are to fall. Bar graphs can be drawn to show the
distribution to the number of raindrops that have fallen into each
square.
How many raindrops are to fall is given by the input value:
Another related activity could be:
How many currants are in the currant bun?
This could have the variation of how many
currants are necessary to put in the baker's mix to
have at least 5 (say) currants in each bun. Look at
median, mean, standard error, maximum values
and calculations from sample simulations.
Refer to the 'Programme Mode Command
List' for entering and editing the program.
