What is Scratch?

dlea — 2014-04-10 20:17:46 UTC

Scratch is a programming language and online community where you can create your own interactive stories, games, and animations-- and share your creations with others around the world.

Why learn programming with Scratch?

dlea — 2014-04-11 04:35:44 UTC

Programming is the future, as we are more technologically advanced we need more people who can read and write in code. We use it for manufacturing, logistics, industry, science, medicine, automation and of course computers and video games. Those who can read and write code will create the future.

How will we use scratch?

dlea — 2014-04-11 04:38:09 UTC

We are going to use scratch to create our own games and interactive cards. We will explore how to tell a computer to think using code.

The upcoming major assignments for this class will be to create an interactive card for any teacher in celebration of Teacher Appreciation Week, May 5-8.

We will also be working on creating our own games using scratch.

Finished early?

Go to the scratch home page and click on explore to see how others have used scratch. Click the SEE INSIDE button to see their code blocks. The best way to learn is to take ideas from other people.

1. Making Characters Move

dlea — 2014-04-11 05:00:24 UTC

You can put motion blocks in the space on the right. Click on the block to make the character execute the action

3. Events (keypress or green flag)

dlea — 2014-04-11 05:00:34 UTC

You can make code happen when certain things happen such as a keypress or when someone presses play.

Sign up for scratch

dlea — 2014-04-11 05:01:22 UTC

go to the webpage below to sign up for an account

7. Make a sprite follow the mouse

dlea — 2014-04-11 05:03:40 UTC

When you click on the sprite the sprite will go to where the mouse pointer is.

2. Using Loops (control blocks)

dlea — 2014-04-11 05:03:48 UTC

You can place one set of blocks inside a repeat loop to make it

work multiple times. Either a specific number of times or forever

4. Adding more sprites to our project

dlea — 2014-04-11 05:08:12 UTC

You can add more sprites using the pre-made library objects, paint your own, use a picture or webcam. Go ahead and add more characters to your project. Take note of Mr. Lea's amazing drawing skills for sprite 2

Change the background

dlea — 2014-04-11 05:08:40 UTC

Again, you can either pick from the library, draw, upload or use a webcam

Follow the basic steps below to create your very first scratch project for this class. Your project will need to use every type of block shown and have multiple sprites.

dlea — 2014-04-11 05:20:56 UTC

Remember that each sprite has its own set of code.

5. Say things

dlea — 2014-04-11 05:22:29 UTC

You can make your character say things in speech bubbles.

6. Play a sound.

dlea — 2014-04-11 05:22:41 UTC

You can also add sound blocks to the project

Turn in!

dlea — 2014-04-11 05:41:35 UTC

To turn in your project you will need to either click the share button on the right side of the screen to create a share link which you can turn in on edmodo.

8. Keyboard Commands

dlea — 2014-04-15 13:21:26 UTC

Use the following code to make your sprite move when you press the arrow keys.

9. Touching Detection

dlea — 2014-04-15 13:42:42 UTC

You can use the following code to make a sprite sense when it it touching another sprite. The example below makes the sprite move away from another sprite.
