Loving the grade level courses! Thank you code.org!!!
One suggestion that I have is to not limit the number of blocks. For example as you move blocks to the work space the number of blocks (ex. move forward decreases 4 --> 3)decrease in number. Although, I see how this could be helpful, it's also limiting. It's my opinion that a student should be able to use as many blocks as they need and then can go back and debug to the suggested number of blocks.
Another suggestion/bug (Course C not sure about other courses) is that students are able to change the language to Spanish. But, only the blocks are in Spanish and not the directions.
My last suggestion is to have the ability to change the course students are enrolled in. As of right now, I believe, you are only able to assign courses for the entire class and not individuals. Allows for differentiation.
