What do you think of Smart Blocks ... ?

Does it work nicely?

Nice Smart Blocks!

They work well....

Please replace

'Move the nlocks around, play with equations.'

with

'Move the blocks around, play with equations.'

A brief note on how the blocks can be manipulated, how to add new blocks, insert numbers/operations etc. would be helpful.

Another novel product from the MathsIsFun factory!

I see that it doesnt do multiplication of negative numbers. I got this equation

Surely that cant be right!

I also got it to tell me that [1] [-] [-1] [=] [0].

Good fun though! I like how it recognises concatenations (eg. [2] [1] [=] [21]).

Why did the vector cross the road?

It wanted to be normal.

Pity it doesnt do division. Im dying to make it divide by 0 and see what happens.

Thanks guys. Good error findings, too.

I got it to say 1=1+1....

How can ** that** be true?

Poor thing only calculates left to right

If you do

12x+=

or something like that it comes up with 0... maybe just call it 'incorrect expression' or something

Good point. Maybe "?" would be neat

If you click on the background and drag around all the blocks on the screen, then when you move a block, all of them move.

Using | | for boxes, I got: |1| = |1| |0| = |10|

Yep ... left to right.

Maybe the "=" should be an arrow. But then it loses its relevance (1+1->2 does not relate to normal teaching of 1+1=2)

BIGx7=BIG?

P.S. Can someone teach me how to take a screenshot? I'm trying to fill the screen with "BIGs".
