Word comprehension and vocabulary game that also teaches donating and "global hunger"

I came across this site while trying to find a way to encourage a little more spelling time. While the kids learn the meanings and spellings of words (levels 1 - 60 provide the ability for those as young as 7 or 8 to start enjoying this game) and when they are correct they see 20 grains of rice added to the bowl on the right. Once you have 100 grains, the bowl is emptied into a bag which you see beside the bowl. You have a visual representation of how well you're doing BUT those grains of rice on the screen represent actual grains of rice that will be donated through the UN World Food Program. Yes, there's an FAQ which explains why, if they have rice available, they don't just donate it without making us play their game. Thank goodness because that was the first question my 8 year old asked. Turns out the game was written by a guy who wanted to help his son study for the SATs!

FreeRice.com - You can change the level underneath the list of choices (start at 1 and it will progress based on how well you answer) and don't forget to show them how to click on the little speaker thingy to HEAR how the word is pronounced. Right or wrong, the word will appear with its definition at the top. When you get the word again, you'll know it - sometimes... hahaha - and hey Moms, isn't it nice to exercise your own brain at a grownup level once in a while? The levels past 30 or 40 can hold challenges for you, too. Push your own vocab up to the 60 level and I'm sure it'll trickle down.
