Warm-ups and Exit Activities with Google Forms

My school district has a Bring Your Own Device (BYOD) policy that allows students to use their smartphones, tablets, laptops in class...for educational purposes.  I really like this program, as it allows my class to have a near 1:1 student to computer ration between my laptop cart and personal devices.  To incorporate (and encourage) students to bring their own device, I started doing warm-ups with Google Forms.  Creating a form with open response questions, multiple choice questions, images etc. is very simple and is compatible with all devices. Student responses are populated in a spreadsheet, which is great for assessment purposes.  What I really love about using forms as a warm-up is that I can quickly see how students are responding to the questions and provide immediate feedback to the class on concepts that students are not quite understanding. Below is an example of a warm-up.  Student's come in to my room, go to the link (that I have shortened with Tinyurl.com), and respond.  Even students who are reluctant writers and discussion participants get into this.  What a great way to get 100% class participation!
