Where can you play the Lemonade Stand game online?

Educational websites like ClassBrain and Coolmath-Games have online, Flash-based versions of Lemonade Stand available to play for free as of 2015. Each site offers its own version of the game, providing a slight variation on the style of play.

For example, the version available at the Oregon Museum of Science and Industry's website only tasks players with setting a price for each cup and how many pitchers to make. The same game at Coolmath-Games asks players to choose how many paper cups, lemons, cups of sugar, and ice cubes to buy before setting a price and tweaking the recipe itself.
