Using Scratch in elementary school to introduce math topics is a great idea.

A little problem to think about ...

It is clearly true that 2 x 2 = 4 and 2 + 2 = 4. Note here that we multiply two numbers and the answer (product) is the same as the sum of the two numbers. Are there any other pairs of numbers that exhibit the same property?

What do you think?

Hey All, a quick question...I just bought 10 chrome books for my Math center and wanted to create an administrative layer so that all of them have the same bookmarks, apps, etc.    

Do I need to buy a special machine from Google or can I set that up myself or have it set up via Best Buy...I am getting conflicting information. Thanks in advance for your help.

2 Quick questions: 1) Can chrome books use external monitors i.e. create dual monitors to work on similar to PCs. 2) Can chrome books drive projectors for presentations.

Thanks in advance for your help!
