Good Job Marnelle!! I like how you gave all the qualifications for making a scribe post. I like the order of how you arranged where you put the definitions to match your pictures. I like how you gave a ling also it helps us learn. I like how you made the words that you were going to explain red so we know that its important. I also liked how you have an example to show us how to do this. Overall that was flawless!
You did an astounding job. I like that the main words are red, which makes it look bold because its a good word and when people see those words red, they know that it must be important and they read the sentence and they know. I even like the pictures/diagrams, they make the scribe post more understanding and colourful. The video and link helped too.
Good job. I like how you added everything you needed and how you made the important words stand out. Good job. I also liked how you made an effort to make pictures.
