Free Addends Game!!

Free Addition Game! In Hawaii they say, "free is a damh good deal, anything more than that and you gotta negotiate."


Act now and we'll throw in a set of steak knives and a bamboo steamer...

If you need the plug in or software to run it you will be automatically forwarded to the Unity site and prompted to down load it. Takes a few seconds...then restart your browser come back here click the green link below again and you are ready to roll...

Their future's so bright they have to wear shades... 

Scroll down for free download!

This is the old version, with my VERY young sons playing it:

CREWTON RAMONE'S ABSOLUTELY AMAZING ADDENDS lays a firm foundation for your child's house of math, by making counting fast. 2 + 2 = 4 is fast and easy for most people but 8 + 7 = 15 might take some thought. So 28 + 7 = ? becomes even more thought even though it's the same problem...and 100.00 - 67.35 = ? seems like a lot of work. Kids who get some exposure to the addends can rattle off 32.65 without much effort at all.

What you get:
Free Addition Game demo lets you build nines & tens.

It has since been upgraded...

Eventually, there will be vids on this page that show you how to use the software, and that shows certain little boys playing with it and so on as well as a shopping cart that will give you a key code to down load the full version for mac or pc OR go to the I-App store and download the app for your I-Phone. For now, the screencast above will have to do.

There are also plenty of free software programs out on the web for teaching +, -, x, /, fractions etc but very few for algebra...more will be built by us as time goes by especially for algebra.

Meantime follow the links on this page. (That don't exist yet.)

Here is a link to some fun stuff under development,

Addends are the basis for all addition, obviously; but are also crucial for subtraction, multiplication and division, which are just ways of counting very quickly. Addends make doing computation FAST AND EASY and best of all FUN. This Free Addition Game will get them off their fingers and help make basic operations simple easy; do not be fooled by the simplicity of this software. It makes a huge difference quickly when children don't have to "think" about it and can just do it.

Freeware: software for your Mac, PC or iPhone; get familiar with the blocks and build nines and tens...just download it and you can start using it NOW. You may need to go to system preferences and make an exception depending on your security settings. 


It's pretty simple to use. You get a nine or ten block on the top of the screen, and three other choices, one of which will "build" the block you are instructed to make...if you get it wrong nothing happens. You just got more information and can try again. If you get it right you get instant positive feedback. Children of all ages should practice until the answers come with ease. The Free Addends Game lets you identify the blocks, and build 9s & 10s.  When you touch the block it tells you its name.

You will probably get this warning if you are a Mac user. Just click the three dots and hit "keep."  Windows users are ever so much smarter than the rest of us so I'm sure you need no instruction. 

FREEWARE to DOWNLOAD to your computer:

From my dropbox:



You need the Unity Player plug in. If you don't already have this plug in installed it won't run.

Again, just click this link to play NOW; above are zip files in my dropbox, below are zip files on this server. You may need to over ride your security, I had to when I downloaded them.

Mac users, just go to preferences and click security & privacy, top row third from the right. Then hit the tab that says general, select anywhere...if you do it ahead of time shouldn't be a problem, if you do it after download, should be a prompt asking if you want to make an exception. Don't forget to change it back to identified developers.

I swear there are no bugs, ticks, or trackers or any other data gathering or back door bullshit. It's a game to help your children learn addends using base 10 blocks.

Directly from the house of math:



No Catch. It's Free.

Put it on a thumb drive and take it to your children's school. Email it as an attachment to friends. I don't care. Just don't sell it. People like free stuff. This is completely free, note you don't even have to put in an email address. So you give them a free app and they find out about Crewton Ramone...if they are curious. You will note there is no link to my website in the app. But there's only one Crewton Ramone, if they look for me they will find me easily. 

You may want to warn them about me ahead of time. But if they want to learn how to use base ten blocks there is no better place on all the internet. Bold claim. Prove me wrong. No brochure makes the hotel look bad so here's somebody else besides me. 

Even at $997 FOR LIFE that is a heck of a deal when you compare the house of math to others.  And I give away free stuff. Like Supremely Simple Subtraction. have to give me your email for that one but you got this app for FREE

Feel free to put it on computers at your school...etc. I had a fun time with my son's public school because they didn't want to get into trouble with the software developer and get tangled up in a license agreement for their computers or violate copyright or whatever. I'm like "It's MY SOFTWARE, I own it, you have my permission. I'm standing right here."

Show this to your system administrator if you need to because they give you a hard time:

"The task of the modern educator is not to cut down jungles, but to irrigate deserts." ~C. S. Lewis

"Education would be so much more effective if its purpose were to ensure that by the time they leave school every boy and girl should know how much they don't know, and be imbued with a lifelong desire to know it." ~Sir William Haley

"I am beginning to suspect all elaborate and special systems of education. They seem to me to be built up on the supposition that every child is a kind of idiot who must be taught to think."~Anne Sullivan
