In my opinion, the most difficult aspect of teaching coding to beginners is getting their attention and getting them engaged. Therefore, the firstgroup of instructional modules in this collection will be designed to help beginners, their parents, and their teachers get started programming with Scratch .

Up until May 9, 2013, the latest version of Scratch was version 1.4. For several days prior to May 9, the Scratch website was shut down to allow the folks at MIT to migrate from version 1.4 to version 2.0.

On May 9, 2013, Scratch version 2.0 was officially released and the Scratch website was reopened reflecting that change. I will have more to say about the new versionof Scratch later. In the meantime, some of the following links may take you to information about the old version, some maytake you to information about the new version, and unfortunately, some may have become broken during the transition.

New features in Scratch 2.0

There are a number of new features in v2.0, some of which are very nice. I will refer you to this preview article that discusses some of those new features.

Internet access is required

There are a couple of critical aspects of v2.0 that I will mention. Although there was a strong web component that involved sharing projects with Scratch v1.4, that version of Scratch was a program that was downloaded, installed on the local machine, and run locally. Once the program was installed on the localmachine, Internet access was nice but no longer required.

Scratch v2.0 requires Internet access to be of any use. The developmentprogram runs online in a browser. Therefore, those without Internet access and those with poor Internet access won't be able to use Scratch v2.0.

Version 1.4 is still available

Fortunately, as of May 2013, it is still possible to download and install v1.4 from (External Link) . Then the program can be run locally without a requirement for Internet access.

The adobe flash player is required

Another critical aspect v2.0 is that the Adobe Flash player must be installed on the local machine to use v2.0. While this may not be a problem in most cases, itis something that potential users of v2.0 should be aware of.

My publications for Scratch v2.0

On the release date for v2.0 (May 9, 2013) , I was about two-thirds complete in the publication of a series of modules designed to connect the fun side of Scratch v1.4 to the serious world of Computer Science. I immediately put that v1.4 series on the back burner and began a newseries built around Scratch v2.0 . However, for the benefit of those who still need information about v1.4, I did not deletethe modules that I had previously published for that version. You will find those modules in this collection in addition to the modules for v2.0.

Wayne and Dennis like to ride the bike path from Riverside Park to the beach. Dennis’s speed is seven miles per hour faster than Wayne’s speed, so it takes Wayne 2 hours to ride to the beach while it takes Dennis 1.5 hours for the ride. Find the speed of both bikers.

from theory: distance [miles] = speed [mph] × time [hours] info #1 speed_Dennis × 1.5 = speed_Wayne × 2 => speed_Wayne = 0.75 × speed_Dennis (i) info #2 speed_Dennis = speed_Wayne + 7 [mph] (ii) use (i) in (ii) => [...] speed_Dennis = 28 mph speed_Wayne = 21 mph
George
Let W be Wayne's speed in miles per hour and D be Dennis's speed in miles per hour. We know that W + 7 = D and W * 2 = D * 1.5. Substituting the first equation into the second: W * 2 = (W + 7) * 1.5 W * 2 = W * 1.5 + 7 * 1.5 0.5 * W = 7 * 1.5 W = 7 * 3 or 21 W is 21 D = W + 7 D = 21 + 7 D = 28

Shakir works at a computer store. His weekly pay will be either a fixed amount, $925, or $500 plus 12% of his total sales. How much should his total sales be for his variable pay option to exceed the fixed amount of $925.
mahnoor Reply
I'm guessing, but it's somewhere around $4335.00 I think
Lewis
12% of sales will need to exceed 925 - 500, or 425 to exceed fixed amount option. What amount of sales does that equal? 425 ÷ (12÷100) = 3541.67. So the answer is sales greater than 3541.67. Check: Sales = 3542 Commission 12%=425.04 Pay = 500 + 425.04 = 925.04. 925.04 > 925.00
