Random.org
Ever so often, we need a simple online tool that just helps with randomness.
Whether it is to randomly pick a student number, flip a coin, or roll the dice…..we need something quick, simple, and free.
That is why I like RANDOM.org – it is simple, and it is free.
Once you go to Random.org you will see that their most popular “tool” is on the upper right. The True Random Number Generator.
Ways to use this:
I use it when randomly picking winners for prizes I pass out every once and a while.
You might use it to randomly pick a student from your classroom.
All you do is put in the TOTAL number of people involved – or objects involved (if you want to start getting creative with opportunities) – I put in 1 and 50 – and then hit GENERATE. And I got the number 42….what number did you get??
It is very easy – very simple – and something you might be able to use often.
My favorite tool though on this page is the Dice Roller.
And personally, I use it to play Farkle and Yahtzee when I have a wee bit of extra time.
But with students, I use it for math.
Follow this link for the spreadsheet I have created: http://www.box.com/s/gzaez7tlhv965vmx5n6h
Have your students set the dice to 3 (to use with this worksheet) and then roll the dice.
They write each die number into the square and then add the numbers up.
You can make your own worksheet and change it from addition to subtraction or multiplication. And you can also set the dice # higher or lower based on your students skill. And this is a very very easy program to use on your Interactive White Board.
It is simple, it is easy – and it is random math practice. Your students will enjoy it!
I also enjoy the Coin Flipper option.
This is a very easy way to introduce your students to probability. Learning.com has put together a lesson plan (w/ worksheets) which you can find here: http://www.learning.com/pdfs/et/activity-35-cointoss.pdf (feel free to adapt it to your students level)
There are many other “free” services at random.org – plus a few $$$ ones as well.
Also – some of the tools you can embed onto your blog, wiki, or website.
It is simple, it is easy – and (grins) it is free!
Enjoy!
