### Ishaka's square roots scribe post

4) Estimate the square root of each number, to one decimal place. Check with a calculator.

a) 72
square root 64 =8 x 8
square root 72 = 8.__x 8.__
square root 81 = 9 x 9

I estimated that 8.49 was the square root of 72 calculator 8.48

b) 103
square root 100 = 10 x 10
square root 103 = 10.__ x 10.__
square root 121 = 11 x 11

I estimated that 10.15 x 10.15 was the square root of 103 calculator 10.14

c) 55
square root 49 = 7 x 7
square root 55 = 7.__ x 7.__
square root 64 = 8 x 8

I estimated that 7.42 x 7.42 was the square root of 55 calculator 7.41

6) What is an example of a whole number that has a square root between 9 and 10?

9 10
81 100

examples: 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99.

1. Good job Ishaka! I like how you typed certain words in bold and used colour. Everything was nice and neat. However, it said to estimate to one decimal place (eg. 1.8) but you estimated to the second(eg 1.89) so next time, make sure do everything correctly. Keep up the good work! :)

2. Good job Ishaka , I liked how you made the 2 questions bold & how you also colored the important parts of the answers , Also i liked how your scribe is very neatly done . Keep up the awesome job! (:

3. Good job Ishaka! I like how you typed certain words in bold and used colour. Everything was organized. Also, I agree with Melanie, it said to estimate to one decimal place but you estimated to the second, next time, make sure to do everything correctly. Keep up the good work Ishaka!(:

4. Good job, Ishaka !
I really liked how you made the fonts different. Your post was really well done. Keep it up :)

5. Good Job! Your post was neat but it could use a bit more color and also the question says that to estimate in 1 decimal place but you estimated in 2 decimal places so next time make sure you read the questions carefully but otherwise Good work

6. Yo,Great Job here Ishaka!Your post was great,but needs some more color,but other than that.Great Job!:)

7. Good Job Ishaka, I agree with Roemer that you should add more color. Your post is neat and understandable. All in all great job !
