Note: You need to download the FREE SUPPLEMENT to use this lesson. The original iPad app is no longer available. The supplement contains new graphics. Tackle the complex lessons of the stock market. This math lesson allows students to study trends in the economy and the workings of investment strategies in a real-world setting...using iPads and a student-friendly “app”: a perfect way for the class to integrate math and technology. Note: this single lesson comes from my complete project-based, Common Core Unit, "Using iPads for the Stock Market", which includes vocabulary, a vocab. test and key and all students need to try their hands at investing in and tracking a stock portfolio. Try it!
