Good Day,
Could someone please explain what a mathematical or arithmetical array is? The array in question is used in grade three math in Ontario. I would also like to know what its purpose is. My E-mail address is;
glanctot@mail.on.rogers.wave.ca. Thank you for your time.
Regards
Gene
Hi Gene,
A mathematical array is a rectangular arrangement of objects. The Saskatchewan curriculum says "an array is an orderly arrangement of objects in columns and rows". The objects are quite often numbers. For example,
3 | 0 | 1 |
-2 | 4 | 0 |
An array is often a useful way to keep a collection of things. My gradebook is an array of with one row for each student and one column for each homework assignment or test. This array is not composed entirely of numbers since the first column contains student names and the first row identifies the test or assignment.
As an example you might create a "pet array" for five students.
dogs | cats | hampsters | fish | |
