If you haven't done this with your students, you are missing all the fun!  The students play the Lemonade Stand Game on coolmathgames.com and input, analyze, graph, and report on their findings using Excel and PowerPoint. 

 I have included a full set of directions in a step by step easy to follow manner and an excel template for the students to input their data..easy, easy and will be completely engaging leaving little for you to do except enjoy them learning while connecting Literacy, Math, & Technology!!!  You can't beat it..I usually allow them a full week to complete the activity and have them present their findings to the class!
