Channels> Khan Academy (English) > Math > 2nd grade > Measurement and data > Picture graphs
The 2 quizzes in that folder require internet to be completed. The quiz is programmed to take the picture from an online server, unlike the other quizzes where the pictures are already downloaded, therefore in offline mode the pictures will not show at all.

This one is the same thing too. The protractor won’t show up without internet.
Channels > Khan Academy (English) > Math > Basic geometry > Angles > Angle types > Benchmark angles

I only completed a few grades, all Quizzes imo. need to be re-checked.
