I was trying to figure out how long in my life I will be using a device, because I want to be more aware of the balance of my life. I estimated that I will be on my device about 5 hours per day.
5 x 365 = 1825 hours per year I estimate that I will live to be about 90 years old because the average estimate for life expectancy is 78 years, but people will live a little longer in the future. 90 x 1825 = 164,250 hours in my lifetime. That means I will be using a device for: 164,250/8760= 18.75 years or 18 years and 9 months. This surprised me because I think I will probably use my phone even more when I am a teenager. I think I use my device well to do research and find information, but I need to make sure I am balanced. To figure out how much time I will spend on a device, I think I did a good job estimating how much time I am using. I also did good converting from hours to years and back. Now I want to know how much time I spend using my notebook and pencil because it will help me find a better balance in my life. I wonder why people use paper instead of computers. Is it more efficient to use a device?

Oh my gosh! Mr.Pug finally gave me a math problem about something I actually know about. I am so excited to solve this problem. This problem is that Jordan wants to start a pin g pong tournament but he wants as much people to play at the same time. So he has to find out how much ping pong tables can fit on the basketball court. I need to help him to find it out.
I had to measure the area of the ping pong table and the basketball court. There was a big difference in the 2 matter but it was fun to figure out the answer. I had to measure the length and the width of both matters. I discovered that not only the ping pong tables need space, but the people need space to play. I didn't really get the part when we were supposed to add the space wider for the ping ping table but I did manage to get it done. It was really surprising when I finish all my calculations and when I saw the result. I will show you the basic calculation underneath. Also even my estimate was exact! I estimated 16 and it is! 1.5m=Width of ping pong table, 3.5m=Length of ping pong table 14m=Width of basketball court, 26m=Length of basketball court 3.5m=The result of space for width added for ping pong table, 6.5m=The result of space for length added for ping pong table 3.5x4=14, 6.5x4=26, So it means 16 ping pong tables can fit on the basketball court. This is my first post on my math page and I am really glad I could share my past work I did. Well I have been measuring a whole bunch of things in during this unit. I am going to share all the units that I know on measuring things. I used length, weight, volume, age and a choice.
I was trying to find out different measurements using different measurement units. With length I used height to measure my height. I found out that I am am 0.00151km tall! It kind of freaked me out. Also I found out that I only lived for 439 weeks! Math is so cool. I think I was good at measuring things in a more simple way than doing it harder. Normally you might think it is hard to convert a meter to a kilo meter, but if you actually do it, it is not that hard. here is an example; I am 1.51m tall. To convert it into a kilo meter is to put 3, 0s at the front. Like; 0.00151. (Remember to put a decimal point after the 1st 0). I did do well in those things but I think I still need to find a more stable age calculation. I didn't get how to like put the decimal point after the 1. (I am 10 if you didn't read my information box). I think it is weird I don't know exactly how old I am but I am myself so yeah. After I measured all this I want to know how big I will be if the whole earth was just 1 cubic meter. check out the link underneath to visit the slide for this post and check out my other posts and youtube videos! |
