This document provides instructions for programming lesson 2. It discusses objects, commands, variables, branching, loops and sub-routines. It instructs students to go to a wikispace website to answer questions and find resources. It provides examples of using objects like a dog named Barry, and using commands and variables in code. It asks students to write their own code using objects, variables, branching and loops. It also discusses variables, pseudocode and flow diagrams for planning programs.

1. PROGRAMMING Lesson 2
BASICS

2. GO TO THE WIKISPACE!
Click the link to answer the
SOCTRATIVE question.

3. LESSON OBJECTIVES
Understand the fundamental principals of object orientated programming:
Objects
Commands All
Variables
AND
Branching
Loops Some
Sub-routines

4. ON THE WIKISPACE!
Go to the
programming page to
get resources you
need

5. USE THE SHEET TO
RECORD YOUR
PROGRESS
You can use this to
help you add to your
revision powerpoint!

6. OBJECTS – SPEND 5 MINS WITH
THIS CODE AND IDENTIFY
WHICH ARE THE OBJECTS AND
WHICH ARE THE COMMANDS?
End

7. OBJECT- DOG
Objects have states.
Dog is brown
Dog is called Barry
AND behaviours
Barry is sitting
Barry is barking

8. OBJECT- DOG
COMMAND!
Barry.fetch(slippers)

9. UPDATE
YOUR SHEET
Objects and Commands!
2 minutes
2mins
End

10. OBJECT- DOG
VARIABLES
Barry.fetch(slippers)
slippers = 2

11. VARIABLES
Where are
the
variables
in the
code?

12. 10 minutes
WRITE YOUR OWN CODE:
At least 4 OBJECTS
At least 3 VARIABLES
Try and include a branch and a
loop!

13. PLENARY
Write your definition of a VARIABLE in socrative
Then
Lets vote on which is the best definition and why

14. LASAGNE INGREDIENTS
Tomatoes
Dried Lasagne Sheets
Minced Pork
Minced Beef
See Recipe for
Homemade Béchamel Sauce Homemade
Béchamel Sauce

15. Can you draw
STARTER a parallel
between this
camel and
anything you
have done so
far in our
programming
project?

16. CAMEL CASE
I want to make a new program to calculate the
interest I am earning on my savings account.
CalculateInterest

17. LESSON OBJECTIVES
Be able to effectively plan our programming projects:
-Using Pseudocode
-And Flow diagrams
Understand why it is important to use pseudocode and flow
diagrams to plan programs.

18. PLANNING PROGRAMS
Pseudo-code – What is it? Why use
it?

19. GROUPS OF 3
Write the pseudocode for a program that makes
lasagne
PROGRAM MakeLasagne:
<Do stuff>
END.

20. BRANCHING OR SELECTION
What if you are cooking for a vegetarian?
You need to branch or select.
Edit your code to reflect this.

21. LOOPS OR ITERATION
What if you need to tell the computer to keep doing
something until a condition occurs?
For example; I want to keep frying the mince until it
is brown.
