Formative is a web-based student response and assessment tool. Teachers can take advantage of a plethora of content showing ideas for use, or they can upload or create assignments on their own that let students type, record audio, enter numbers, draw (with a mouse or their finger, depending on the device), upload an image, answer multiple-choice questions, and more.
