OR
, and are Perfect Squares

Any number can be a square.
Example: 20

You can use your calculator and punch in √(square root) 20, or 20 if there is an error.
20=4.472135955. OR 4.47.

HOMEWORK: Tell me what you know about squares.
Find out what you know about these squares: [1] [2] [3] [4] [5] [6] [7] [8] [9]

1. A fairly helpful post, Patrick. Although, I would've liked to see a link to a site or even a video. I liked your picture nonetheless and the colors were a nice touch, just remember not to go too overboard with them. Here's a link to a site which I thought would be useful:http://www.maths.com/numbers.square.htm. There should be 2 videos there too. I hope that helped even a little bit. Keep up the great work.

2. Great job Patrick! I liked the picture you used, it helps the reader visualize the intervals better. I also liked the colours you used to emphasize the important words, it's always nice to have a splash of colour here and there. By the way, thanks for putting the homework, that could be very helpful for students who didn't have time to write it down at the end of class (like me), very thoughtful! Well, again great post, keep up the good work!

3. Great Job on the post Patrick. The picture you made is very helpful for the people that are having trouble visualizing the number line. Your examples for square root was also helpful because
it gives the solver the way to figure out the square root, Great job.

4. Good job, Patrick! I liked that you had a picture of a number line and that you changed the colours of some words to show importance. But next time put a link, and a video! Other than that, good job!

5. Good job Patrick. I like how clear you made you picture and how you made words and/or numbers a different color. I also liked your example for square rooting. Next time, you should have a link to help explain it more. But overall, good job again.

6. Great job, Patrick! The picture of the number line is very clear and understandable, so are your explanations of how to find a square root. I like how you changed the color of the fonts for the important words so that they could stand out.
Next time, you should of put up a link or a video to help explain this post more, but nonehtheless, it was a great post!

7. Good job, Patrick. I liked how you made the number line in the picture. Very understandable to read. Also, it's nice to see the important words colored in so they could stand out and the example for the square rooting. Next time, add a link and video. But overall, good job.

10. Great post Patrick. Its good that you included the homework and I liked that you added the small detail of the error on the calculator. But one thing you should have done was add was a link like everyone else mentioned and I agree that the font makes things stand out. I also like the picture that you added.

11. Great post Patrick! I liked the colours (although some were a bit bright) and I liked the picture of the number line you put for us. Your post was very understandable and it was a great summary of what we did in class, great job!
