Good job, Julibella! You did a fantastic scribe post! I really liked your work that you showed to explain the question, but next time try to make the pictures more clear. They were a little hard to read and also maybe you want to add a link next time too. Overall it was a great scribe post!

ReplyDeleteGreat job Julibella, you did a wonderful job of your post. I really liked how you did your work on paper and just took a photo of it. A suggestion is that maybe next time you should use a pen or marker when writing to let it stand out and it's more appealing and easier to see. But your post was really well done! Keep up the good work in class too.

ReplyDeleteGood job Julibella. Your pictures are clear but try to make them clearer next time. Other than that, good job. Keep up the good work.

ReplyDeleteGreat job Julibella. Your post was very neat, organized and well explained. Your pictures were nice and neat but a link to your post would make it better.

ReplyDeleteGreat job Julibella. I liked how you took pictures of your own work and it was really neat so it was easy to read and understand. Next time add a link to make you post better. Other than that, great job.
