New "Manipulative" called "Smart Blocks"

What do you think of Smart Blocks ... ?

Does it work nicely?

Re: New "Manipulative" called "Smart Blocks"

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! smile

Re: New "Manipulative" called "Smart Blocks"

I see that it doesn’t do multiplication of negative numbers. I got this equation

Surely that can’t be right! yikes

Re: New "Manipulative" called "Smart Blocks"

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 doesn’t do division. I’m dying to make it divide by 0 and see what happens. tongue

Thanks guys. Good error findings, too.

Re: New "Manipulative" called "Smart Blocks"

I got it to say 1=1+1....
How can that be true?

Re: New "Manipulative" called "Smart Blocks"

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.

Re: New "Manipulative" called "Smart Blocks"

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

Re: New "Manipulative" called "Smart Blocks"

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".
