GridMaths.com beta : Grid paper for your screen

[gord]

This came out of watching my son do some long multiplication.  I thought there ought to be a way to save paper, line up columns better and get less typos.. and it kind of snowballed from there.  

beta demo : GridMaths.com

background : quantblog.wordpress.com

Tell me what you think, ideally if you have young learners or prepare lesson plans,

bests,

gord

Does it not work on Chrome?

I'm having problems.

But I think the idea is awesome.

I wasn't having any issues in Chrome.

Bon, Thanks.

Im using it on Chrome [ but very recent Chrome on Linux with a PC screen ] .. 

What isn't working?  

Can you use ^ button on the menu bottom left to show sample sheets? 

If its a UI issue, a screenshot might help me track it down ? 

Also Ctrl-Shift-I on chrome can show any console errors.

Thanks for trying it out.. obviously I will gradually test on more browser OS combinations, tweak for iPad etc as we progress.

Is it something similar to the Model Method of Singapore Math ?

[gord]

Well Id say GridMaths is a tool, not a model per se...  you can use it with any 'model' of teaching.

But yeah, I guess most of my examples have a similar feel to Singapore Model maths approach, eg. show lots of measurable things to help build intuition.

Quisenaire measuring rods and counting beans are pretty universal and probably pre-date Singapore methods.. but all of these are great approaches.

I'll be interested to see people make lessons in GridMaths using their favourite method.

I've been thinking that something like Gridmath, but 3D, and with built in "challenges" would be a very interesting learning space for building up numeracy & spatial math skills. I'd like it to look a little bit like Minecraft, but not quite as open-ended. I like Gridmath because it is somewhat open-ended but many activities you do it with the tools provided are likely to lead to mathematical thinking.

I wonder what Gridmath + Turtle Art-like scripting + 3D would look like...

You had me at "Minecraft".. my son loves that!

In GridMaths I'm working on having scripted 'worked problems' which you can either step thru to learn, or run in "quizz mode" where it asks for each step.

3D would be very engaging.. it might be a lto of work to build it.  Maybe you could start with something simpler, and prototype within Minecraft?  

Hmm.. just dawned on me that Minecraft would be a great way to do a lesson on Volume.  

How cool would it be for a maths teacher to bring up the video game and talk about volumes.. and how you can approximate arbitrary curved shapes with cubes !

I am working on a Minecraft server for us math folks. Several Math Circles people are interested as well. We could build it up with all sorts of interesting objects!

Gord, building a better graph paper is such a worthy cause! Thank you for doing it. I am planning to re-launch the Math Future event series; we should definitely talk about this project of yours!

It popped up in this thread so could  any of you give me some advice on Minecraft for Math ? For algebra and geometry, if possible.

Happy to contribute or test in classroom.

Minecraft is a 3D grid world, so it lends itself to discrete methods in any subjects. For example, difference calculus.

I just wanted to thank Gord again for the tool. I have been using it this morning to illustrate activities for Oleg Geizer's young math book. Love the "Fun buttons keyboard" interface!

Hey thanks Maria, 

Great to hear its useful already..  I just had to add those jellybeans..and coffeebeans for parents :]

My son and I were using the length rods to solve LCM problems the other day .. seems like a lot of things in Math are easier to grasp when made visual.   

Please keep sending suggestions on what you would like to see in GridMaths

Nice book btw, lots of deep concepts introduced there.

I would like to see an eraser! 

[Gordon Anderson]

Maria,

You can erase the last edit by |<- key, or use < and > to move to the edit, and then erase at that point.

Yes, its not as intuitive as a normal eraser.. thats on my todo list :]
