Draw Slide App allows you to turn any Slide image into a drawing canvas for students to draw and submit to you. There are also predefined backgrounds, namely the grid coordinate, integer scale, World map and USA map. If you do not want to allow changes to be done in the answer after submission, deactivate the 'Allow answer changes'.
You can resize the Draw Slide App to fit the area that you wish the students to draw in as well. Combine this with other Slide Apps to make a Meme!
The Draw Slide App is particularly useful for Chinese language teachers who would like to see their students write out Chinese characters on screen.
