Test 1 - Topic 1—System fundamentals with Questions and Answers Test 1: 1.1.1 Identify the context for which a new system is planned. Test 2- 1.1.2 Describe the need for change management.

Lesson Objectives: Lesson 1 All of you will… Draw simple shapes using the turtle Understand the use of different commands such as move forward, backward, left, right Most of you will… Use computational thinking skills to look for repeating patterns and include them in your programming Lesson 2 Understand the motion commands with Python turtle module Understand the use of Variables and how to assign them values. Understand the use of different commands such as PenUp/PenDown, goto, forward, backward, left, right and t.begin_fill() & t.end_fill(), t.goto(x,y), t.setposition(x,y), t.pensize(value), t.setheading(value), t.color(‘green’) Lesson 3 What you’re aiming for in this lesson is to: familiarize yourself with the various code statements play with the code and learn how to change and adapt it. For example, if you have the code for a small red square, you should be able to change it to make a big yellow square. be able to use the code we have developed for various shapes to create a picture.
