The Locker Issue in SST

An impending headache to the administrator in planning the locker operation in SST. He seeks your advise on how to resolve this issue:

Here is the problem:

Task: In SST, there is a row of 100 closed lockers numbered 1 to 100. A student goes through the row and opens every locker. A second student goes through the row and for every second locker if it is closed, she opens it and if it is opened, she closes it. A third student does the same thing for every third, a fourth for every fourth locker and so on, all the way to the 100th locker. The goal of the problem is to determine which lockers will be open at the end of the process.

Sample Questions:

In words, explain your thinking to the following problems clearly. Be sure to use appropriate mathematical language and methods:

Which lockers remain open after the 100th student has passed?

If there were 500 students and lockers, which lockers remain opened after the 500tth student has passed?


Further Activity:

Identify another problem that uses the same method or technique to solve and post it to this blog

  • Learning Environment

History of Numbers

'A number is a mathematical object used in counting and measuring. A notational symbol which represents a number is called a numeral, but in common usage the word number is used for both the abstract object and the symbol, as well as for the word for the number. In addition to their use in counting and measuring, numerals are often used for labels (telephone numbers), for ordering (serial numbers), and for codes (ISBNs). In mathematics, the definition of number has been extended over the years to include such numbers as 0, negative numbers, rational numbers, irrational numbers, and complex numbers.' wikipedia
Another interesting factor to note is that numbers is a form of a universal language and appears in every civilization.
Task 1: View the following video to have a better perspective of maths
history of Maths
Identify 3 points that you have discovered from the video.

Task 2: Number System through the years
Identify a civilization and do a brief presentation of not more than 1 minute on the number system of the chosen civilization. You may identify, if any, a key pattern of the number system of that civilization with our present number system. You may choose any more of on-line presentation and upload to this site.
