Mrs Yglesias Earhart Middle School Review

I enjoyed using the Lemonade Stand game to teach my students about Microsoft Excel and Power Point. They played the game for 2 weeks keeping data about purchases and sales, created graphs and captured screen shots for their Power point presentation. I liked it.

Mancala game cheats

I saw some students playing Mancala during a studyhall one day and thought I'd give in a try. After playing hundreds of games and keeping count on my own, I can safely state that the Mancala game is rigged. The computer cheats and when you play to a draw or even win the computer wins. I don't know why they have designed the site this way but they have. Maybe they make money the more time you spend there trying to win? All I know is the game is a cheat.

I love this website

You have to go on and try cofee shop and lemonade stand. I am 12 and have been going on coolmath for over a year.Some games are easy enough for an 8 year old but some may be too hard. Just be careful because you may become angry when you can not win the game.
