Make a graph for the following info. 3 kids use the computer 1-3 days per week.
9 kids use the computer 0 days per week. 18 kids use the computer 4 or more days per week.
Step 1. Find out how many in total.
3+9+18= 30
Step 2. Convert to %
3 = 1 = 10 10% 1-3 days
30 10 100
9 = 3 = 30 30% 0 days
30 10 100
18 = 6 = 60 60% 4 or more days
30 10 100
%|degrees
100|360
50 | 180
25 | 90
10 | 36
Convert % to degrees.
10% of 360= 36 degrees
use a protractor to measure the central angle
30% of 360= 108 degrees
60% of 360= 216 degrees

Great Post Errol ! You explained evergything really well. The things you should of put on it is a link and you should change some of you font to different colours for attention. Anyways Excellent Job ! (:
ReplyDeleteGreat post Errol! Everything was clear and made sense. I like how you made some of the important things a bright colour so they stood out. In your circle graph that showed the different flavours you forgot to put the "degrees" marks after the numbers. My only suggestions are that you should have put a link and more colours and fonts like Glenn said. Good Job!C:
ReplyDeleteGreat job Errol! Nice pictures, but next time you should add more colours too them. Also use different colours in the font. It was really good that you included all the notes and the homework. Your post could be inproved by adding a link or video, or maybe even both. Other than that, good job. (:
