Good post, Summer. Your post was very detailed and told us all the answers to the questions, but you still could have posted a video to go with them. You could have also shown your work for number 11. Otherwise, a great post.

ReplyDeleteGood Job Summer! Your post was really neat and very colourful. You should of showed how you got the answer for number 19. But I liked how you showed the work for the other numbers. Good job, keep it up!

ReplyDeleteGood job Summer! I liked that you highlighted the important words. If I were you, I wouldn't have made the text so big. Besides that, you did a very good job!

ReplyDeleteGood job Summer! I like how you added some color to your post. Next time you should make your font size a bit smaller! But over all great job!

ReplyDeleteGood Job Summer. I like your post its very simple. I dont get the line at the bottom of the page. Like what Jomer said ^ you should've showed your work for number 13. Good Job .

ReplyDeleteGreat job Summer! I like how you used color wisely, and it was very neat and organized, as anna said you should make sure to show your wok for everything. Other than that, great job!

ReplyDeleteNice posts Summer! I really liked the way you used the colour to highlight the important facts. One thing you could have done differently is for # 19 you just put the answer next time you do a post you should show how you got it because that could really help some kids. but keep up the good work.

ReplyDeleteGood Job Summer! I like how you changed the color of the font for the important words. Next time don't use bright colors. Good job.

ReplyDeleteGood job Summer! I liked how you highlited important words. I agree with Marysa, for number 19 you should've put how you got the answer. But, good job though.
