- 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!
