Great scribe post, for your first number line you accidentally switched the positive and the negative number. The positive should be at the top and the negative should be at the bottom. I love the effort you put into this post!
ReplyDeleteGood job on the scribe post! Maybe just describe what you're doing more, otherwise good job!
