Grades IV‑VI

I. Understanding, analyzing and solving problems. The student:

2) formulates and writes in the form of algorithms commands consisting of:

c) controlling the robot or object on the screen;

3) distinguishes basic steps in algorithmic problem solving: determination of the problem and goal to be achieved, analysis of the problem situation, developing a solution, checking the problem solution for example data, writing the solution in the form of a diagram or program.

II. Programming and solving problems with the use of computer and other digital devices. The student:

1) designs, creates and writes in a visual programming language:

a) ideas of stories and solutions to problems, including simple algorithms using sequential, conditional and iterative commands and events,
b) a simple program that controls a robot or other object on the computer screen;

LESSON STAGES

Introductionmcfe36a7ac69b1329_1528450127855_0Introduction

Answer the introductory questions:

1. What computer games do you play most often
2. What skills and knowledge do you have to have to create such a game? What is the name of professional who creates such games?
3. What is programming?

Discuss your answers with other students.

Proceduremcfe36a7ac69b1329_1528446435040_0Procedure

Students read the text and then follow the instructions:

Each of you likes to play a game sometimes, maybe it's worth trying to create one on your own?

To start with a simple one, but over time, if you gain experience, you will certainly be able to get involved in a more advanced projects.

You have to start the process of game creation with little steps.

Let's start with the Scratch environmentscratch environmentScratch environment.

What is Scratch? It is a programming environment that allows you to create simple applications using sounds, allowing you to draw and choose colors, etc. It is available to everyone, because you can use it completely free of charge and both install it on a computer and work on the network. Scratch should work on every computer regardless of the operating system installed. If you want to share your work with others, it will be possible from any place that has access to the Internet, because projects made using this application can be shared on the Internet. Using Scratch does not require prior knowledge of any programming languageprogramming languageprogramming language.

All programs written in Scratch are built using blocks. Blocks have different colors depending on which group of commands they belong to. All commands are printed on blocks, in Polish, English or any other language depending on the language chosen.

So it's time to get to know the environment.

1. Go to www.scratch.mit.edu.
2. Select the Create icon.

3. After selecting the Create icon on the screen you will see the following image. To see the functions of each element, click on the numbers in the figure below.

[Interactive graphics]

Pay attention to the shape of the blocks. They look like a puzzle. They match others.

To create your own design you have to choose: the spritespritesprite (character), the stagestagestage and give the sprite some instructions. Commands from which your program will consist of should be moved from the block area to the program building area. First select the commandcommandcommand you are interested in by clicking on the appropriate block, then drag it to the program building area and release the mouse buttonbuttonbutton.

If it turns out that too many sprites are on the stage, you can remove the unwanted sprite by selecting the icon of scissors on the top of the program, and then clicking on the spritespritesprite to be removed.

Check also what Scratch's producers have prepared for you. Choose elements from the initial projects to learn the program. And now it's time to use knowledge in practice.

Task 1

Make a simple animation, e.g. a butterfly which follows the mouse cursor. To do this, choose a butterfly from the sprite block. Then from the „Events” tab select the „When clicked (green flag)” button, then from the „Control” tab select „Always” and now from the „Motion” tab select „point in the direction” and then „Move … steps „. Put these commands inside the „Always” command. Name the butterfly. To do this, click on the letter and that is on the butterfly icon on the left at the bottom of the screen.mcfe36a7ac69b1329_1527752256679_0Make a simple animation, e.g. a butterfly which follows the mouse cursor.

Now just click on the green flag and .... well done, you have just completed your first project.mcfe36a7ac69b1329_1527752256679_0Now just click on the green flag and .... well done, you have just completed your first project.

Task 2

Save your project. To do this, create your account using the log in icon in the upper right corner of the screen. Remember to use the network securely and set strong passwords. By saving your project you can share it with anybody who is connected to the Internet.
