Hi Dinko,
I'm back to my computer for the evening but will be gone again tomorrow and
until Sunday. I did take an XO and use Pippy to check things in some of the
files you sent. I will do a separate one for each section. I might be able to
check some of the others before I get back on Sunday.

Here are some comments and corrections, shown in red:
2.0 Variables:
Even if you can't guess what the result will be, you can run it and see that
this will output (write) the number 3 to the screen - exactly the same as if
you had written "print 15 / 5". However, this time we have stored the numbers 5
and 15 under the names "a" and "b". You can picture it as if we put those
numbers in boxes, and wrote "a" and "b" on those boxes.Students may have
learned this concept as it applies to math in some "pre-algebra" lessons they
had in 5th or 6th grade... you may wish to draw a parallel.**# example
startprint "Sixth example:"a = (3+9)/2 -(1 + 5)print a# example endAgain,
average to good students should be able to evaluate expressions like this by
6th or even 5th grade.
** # example startprint "Eighth example:"number = 5number = number + 1print
number# example endTypo: missing letter "h" ** What do you think happens
when you write an expression after "print" (examples 1, 2 and 3)? Just as when
assigning values to variables, the expression gets calculated to a value, and
the value is printed.Typo: missing word "as" could also use "like"
