ABOUT
• You will be learning programming independently at your own pace.
• Your teacher will help you when you are stuck, but you are encouraged to use
“three before me.” That means you look at your code first, then ask two friends to help you
before asking your teacher.
• The course has 10 workbooks introducing you to new commands.
• Each workbook has 4 sections:
• T - Try
• I - Investigate
• M - Make
• E - Evaluate.
• Becoming a good programmer takes TIME!

TRY
• In the “try” stage, look at the
program and predict what it will do.
• Type the program or copy and paste
it into your development
environment.
• The program definitely works, so if
yours doesn’t check it again
carefully!
Some useful things to try are
listed in the notes section of
the slide.

TRY
You probably wrote a program like this in the past:
# Program to convert kilograms to stones
Kilograms = float(input("Enter the number of kilograms: "))
Stones = Kilograms / 6.35029
print(Kilograms, "Kg", "is", Stones, "Stones")
This approach is fine for learning at Key Stage 3 where you want to keep programming simple.
At GCSE and A level we learn that code should always be structured into subroutines to create self-
contained, reusable components and inputs should be prevented from crashing the program!
Simple programs will therefore look more complicated now!

INVESTIGATE
• In the “investigate” stage, read how
the program works.
Changes you need to make to
the program are shown in the
notes section of the slide.
Do these before continuing.

INVESTIGATE
• In the “investigate” stage, there is a summary of the theory knowledge and subject specific
vocabulary. This may help you answer the questions on the following slides.
