Placemarker Slide App turns any Slide image into a quick response activity. You can also choose from a predefined set of commonly used backgrounds, namely the grid coordinate, the world map and USA map. This is a free-form response and no validation of answers is provided. Use the Drag n Drop Slide App if you need validated, fixed answers.
If you do not want to allow changes to be done in the answer after submission, deactivate the 'Allow answer changes'.
Students can drag their unique Placemarkers containing their avatars to the image which is mirrored to the Teacher's view.
