Variables are used in Scratch to store numeric information. You have learned about variables in Math, how they store or represent numbers that are unknown. A simple way to explain this is that variables store numbers that change over time. Think about a score in a game, or is your character has lives or strengths; these are numbers that change depending upon what else is happening in the program. Just like when you solve or balance an equation, if you change x, then y must change.
The example I showed in class was a simple race track with cars moving around and a variable that counted the number of times the car crossed the finish line (the number of laps).
Here are some race examples that students have created to demonstrate the concept.

Conditional statements ask a question, then, depending upon the answer, execute a sequence of statements.
IF (specific condition is met) THEN (do this action)
Try out some of these ideas for your Scratch if a condition is met: change sprite size, change sprite visibility, change sprite location, change sprite color, change sprite effect.
Here are some student examples:

If you haven’t handed your completed Scratch animation in to the hand-in folder, please do - that way I can post it on The Computer School website. I am also uploading projects to the Scratch MIT website, if you have nominations for what projects should be posted there, please let me know.
This week we start investigating programming concepts. The first one we will look at is SEQUENCE.
“In a sequence structure, an action, or event, leads to the next ordered action in a predetermined order. ”
Here are a couple of student examples from this week’s classwork:

I am in the process of posting the completed Scratch animations on the Computer School website. As students hand in their completed and peer reviewed files, I will post them to the website. Please take a look. You can also satisfy your peer-review assignment by reviewing one of the assignments from online, but you must fill out the peer-review sheet and turn it in for a grade.

We are having a quiz this week on Scratch commands. You will be asked to “translate” blocks of commands and describe what effect they have on a sprite. If you have been trying out the different commands in your Scratch assignment, you should not have any problem with this.
REMINDER
This is the last week of this marking period - report cards will be distributed January 31 (Thursday). Make sure you have all your work completed and turned in. See Teacher Ease, or the chalkboard in the computer lab, for a list of assignments, quizzes and projects due this marking period.
