1. Great job on your scribe, you could've explained what you're doing with questions 5 and 7 which is repeated addition. Also just a handy tip, you can use and 'x' as the multiply sign. i also liked your pictures, it helped understand what you're doing in terms of repeated addition. Also add a video! Oh and it would be helpful to show more work on questions 15 and 17 to show how to do and to show you understand.
