LESSON OBJECTIVES

Understand the fundamental principals of object orientated programming:

Objects

Commands

Variables

AND

Branching

Loops

Sub-routines

Go to the programming page to get resources you need

USE THE SHEET TO RECORD YOUR PROGRESSYou can use this to help you add to your revision powerpoint!

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

End

OBJECT- DOGObjects have states.

Dog is brown

Dog is called Barry

AND behaviours

Barry is sitting

Barry is barking

OBJECT- DOG COMMAND!

Barry.fetch(slippers)

OBJECT- DOG VARIABLES

Barry.fetch(slippers)

slippers = 2

VARIABLES

Where are the variables in the code?

WRITE YOUR OWN CODE:

At least 4 OBJECTS

At least 3 VARIABLES

Try and include a branch and a loop!

10 minutes

PLENARY

Write your definition of a VARIABLE in socrative

Then

Lets vote on which is the best definition and why

LASAGNE INGREDIENTS

Tomatoes

Dried Lasagne Sheets

Minced Pork

STARTER

Can you draw

a parallel

between this

camel and

anything you

have done so

far in our

programming

project?

CAMEL CASE

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

CalculateInterest

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.

PLANNING PROGRAMS

Pseudo-code – What is it? Why use it?

GROUPS OF 3

Write the pseudocode for a program that makes lasagne

PROGRAM MakeLasagne:

<Do stuff>

END.

BRANCHING OR SELECTION

What if you are cooking for a vegetarian?

You need to branch or select.

Edit your code to reflect this.

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.
