Here is a great exercise to reinforce CONCATENATE, UPPER, RIGHT, LEFT, LOWER functions. Get your students to create their own password generator based on various factors.
In the image below you can see how the first 5 columns contain various data. Column 1 is the lowercase alphabet, Column 2 contains numbers descending from 26 to 1, Column C is the alphabet descending but in uppercase, Column D is ascending numbers 1 to 26 and Column E are special characters (Shift key 1 to 0).
We then have a first name and last name in Columns F and G. In Column H is where the magic happens!
I have created posters that you can stick up in your class. There are 33 posters. Below is an index of what functions are available and a sample sheet (to the right) showing what the posters look like. You can purchase them from the Tech Teachers online shop.
