Projects and Investigations
1) Pick any two digit number, reverse it and add the result to
the number you started with. The answer will be divisible by 11.
Is this true for all two digit numbers and if so why ?
example : our number = 53
reverse it = 35
sum = 88 which is divisible by 11
Investigate the case for three digit numbers.
2) You have been chosen to plan a holiday for your family in
France, over a fourteen day period, in the summer holiday.
Investigate fully the costs involved by visiting travel agents
and obtaining brochures etc.
Don't forget to include everything; meals, excursions, presents
etc. Consider what you would do if you were set a budget of £22O
for each person.
Find rates of exchange and draw a conversion graph/table. Include
pictures/maps to make your project more interesting.
3) Write a computer program to illustrate one or more of the
following mathematical ideas:
a) Test whether a number is prime
b) Find all the prime numbers up to a given limit
c) Find the prime factors of a given number
d) A conversion program for Km to miles, gallons
to litres, °F to °C etc..
e) Test if a number is a square, rectangular or
a cube number.
4) Investigate divisibility:
a) by 4 : design a test to say if any given
number is divisible by 4.
b) by 6 : " " " "
c) by 9 : " " " "
Interesting Note: To determine if a number is divisible by 3, add
all the digits in that number. If that sum is divisible by 3 then
the number itself is also divisible by 3 !
example number : 1287
add digits: 1+2+8+7 = 18
add digits: 1+8 = 9
9 is divisible by 3 therefore so is 1287
Final Note:
Remember the examiner is looking for mathematics content
in your project work as well as presentation etc. so writing down
lists and pretty drawings may help but they will not get you that
most important grade!
