1. Intro to Programming with Scratch
Halloween Edition

2. Problem Solving Programming is just solving problems and challenges:
Read and understand the problem: What are you making?
Design a solution: What will your program do? What will it look like?
Implement the solution: Coding time!!
Test solution: Does your program work the way you want it to?
Revise as needed: If it doesn’t work the way you want, fix and test as much as you need
Use get ready to school as an example

3. Computer Programming Writing programs is like solving any problems
We give the computer a sequence of instructions, and the computer does exactly what you tell it to do
You can think of these instructions as steps to solve a problem
Example: How do you make a cake?
Step 1: Preheat the oven
Step 2: Mix all the ingredients together
Step 3: Put the mixture in a pan
Step 4: Put the pan in the oven for 45 minutes
Step 5: Let the pan cool, transfer to a plate and enjoy!!

4. Scratch Go to scratch.mit.edu
Scratch creates stories, games, animations:
Sprites: main characters(objects) in your story
Task1: Draw a Character
Visual coding is great for beginners at any age. Ask if the kids are interested in making andriod applicaitons

5. Scripts in Scratch Scripts = Code Events
Execute code when certain things happen
Task 2: Write Script so that when you click on green flag, your character ask “Hello World!”
Go through example online
Events: When something happens….. (do something)
Control/Sensing: Use sensing to fill in if-statements. Used for collisions, and movement
Motion: Move sprites… das about it
Looks: Shows and hides things and makes sprites talk
Operators: usually used with if statements
MSEN Maze: THIS IS FOR INSTRUCTOR AS A “CHEAT SHEET” please create the maze game on the projector and help the kids along with the game. Have one person do one step at a time at the projector, and at least two people walking around helping out kids that may lag behind.

6. Scripts in Scratch Scripts = Code
Control Flow:
forever; if, then; if, else; repeat until
Sensing & Motion
When you character sense a situation, do sth.
Task 3: a) Write script so if you click up arrow on keyboard, your character move up; b) write similar script for down, left and right c) make your character able to do this forever.

7. Lets start a Maze project
Task 4: Let’s make a puzzle Game:
Create a new Sprite: draw a maze
Create a new Sprite: your prize, put it at the end of the maze
Use the script in Task 1-3, does it work? how to make your character doesn’t go through walls

8. Let's start a Maze project
Task 5: Have time and score in your game
In Data, Create a variable score, a variable time
set score and time equals 0. where should you set it?
how to make time change 1 every second?

9. Let's start a Maze project
Task 6: Make your game more fine
Add traps in the maze
your character should be able to move around the trap, so make it small
when touch a trap, minus point
Add an enemy
the enemy move by itself (use glide)
if your character touched the enemy, go back to the start
Add a sphinx,
you can only pass if you correctly answer a math question
hint: use ask, answer, and if control to test the answer’s correctness

10. Save & Play Each other’s Game
Hurah!!!
