Just wondering if there is an answer key for the Extension Activity: Modify an Image. Thanks!
There doesn’t look to be an answer key, but if one is created any time soon, I’ll be sure to update here.
Not an official answer key but…
To go from a 5x5 to a 10x10 you need to duplicate each bit in the row and then duplicate the row itself.
The image goes from 25 pixels to 100.
Also @fair.danielle , @hannah has responded to your request by creating and posting a complete key (in the blue “For teachers only” box): https://studio.code.org/s/csp2-2018/stage/3/puzzle/1
