Homework Weeks 9 and 19 term 3

This homework task will go over the next two weeks. It is due onThursday 19th of September.
You are to design a classroom of the future.
Image we have turned he clocks forward 50 years.
We have learnt this term that things are very different now from what they were in the past, so just imagine how they will be different they will be in the future.
You can present your plan in any way you choose.
I can’t wait to see what you come up with.

24 hour clock

Converting between 12 and 24-hour time

What is 12-hour time?

What we see on a clock with hands, it is marked 1 to 12 to show the time. This is shown on an analogue clock.

How many hours are there in a day? 24

A 24-hour day is divided into 2 parts of 12 hours each, AM and PM

AM stands for ante-meridiam (Latin term meaning before midday)

PM stands for post-meridiam (Latin term meaning after midday)

What is 24-hour time?

We see this system of time written in 4 digits and describe it in ‘hundred hours’. It is shown on a digital clock.

24-hour system is used everyday in France and throughout Europe. It is used specifically by scientists and the military because it so precise.

The main reason why 24-hour time is described in hundred hours is to avoid confusion with 12-hour time, specifically regarding the hours before midday. For example 03:00 can’t be described at ‘3 hours’ because it sounds like a length of time rather than a reading, so ‘three hundred hours’ is used. The ‘hundred’ is another way of saying :00.

How many hours are there in a day? 24

A 24-hour clock is not divided into 2 parts of 12 hours each but is a continuous period of 24 hours

How do we convert 12-hour time to 24-hour time? Remember the AM hours remain the same.

Add 12 to the hours and keep the minutes the same.

9.45 PM = 9+12 = 21:45

How do we convert 24-hour time to 12-hour time? Remember the AM hours remain the same.

Subtract 12 from the hours and keep the minutes the same.

21:45 = 21-12 = 9.45 PM

Pascal’s Triangle

One of the most interesting Number Patterns is Pascal’s Triangle (named after Blaise Pascal, a famous French Mathematician and Philosopher).

To build the triangle, start with “1” at the top, then continue placing numbers below it in a triangular pattern.

Each number is just the two numbers above it added together (except for the edges, which are all “1”).
Discover more about Pascal’s Triangle on the following websites.

Copy the grid from this website and complete the triangle. How far can you go. Can you see any number patterns.

Information Reports

This week we have been writing information reports, concentrating on the correct use of paragraphs in our work.
We wrote a report on how we use our class blog.
Here are some of the comments we made.
I like using the blog because it’s really interactive and you can send comments.Tai
At home the blog is used to help us with our homework. If we don’t go to school then we can look at the blog and do our work from home. The links Sonya puts on it helps us with our work. Nandita
At home we use our our blog for a lot of things. Firstly we use the blog to check up on our homework. Secondly, we use it to check up on unfinished work. Finally, we use it to message Sonya.
I think it is a pretty good idea for our class. Don’t you? Hamish
We use the blog at home to find our homework for the week. We also use it at home to show our families what we have been doing at school. Lila
Our class blog is very useful. It is kind of like a class diary. Sonya had the idea and we all chose the name. Ruby
When we use our class blog at school we normally have a set task. Sonya puts the information we need to know and any links which may help us with our work. Aidan
I like using the blog. It is cool. Sonya puts our work on there so we know what to do. It’s great for helping us with our learning. Ollie
The class blog is good for parents. They can see what Sonya has taught us. Darren
Our class. Blog is a record of what we have done and what we will be doing. We often find links for the next task we are going to do. Marcus
Our class blog is practically an online assignment book to find tasks and resources to help us do the task. Duncan
Our class blog is so useful and it helps us so much. Plus we can access it whenever we like both at school and at home. Nicholas
At school, Sonya puts most of our work on the blog. Then she just mirrors it using Apple TV on the big screen. It is a great way for Sonya to share what we are doing. If we get stuck we can just go onto the blog and use the information there to help us. Grace
The blog is a great way to share what has been happening at school with my family. It is also good because it helps with home activities and homework. Erin

Our thoughts on the Federal Election

This weekend all Australian’s over the age of 18 have to vote in the Federal Election.
We talked about this in class and these are some of our thoughts.
I’m really interested to know who wins the election.
I really like to be old enough to vote.
I think Tony Abbott is going to win.
I think Kevin Rudd is going to win.
I think it would be cool to be old enough to vote because then you get a say on who you want the Prime Minister to be.
I’m looking forward to going to the Polling Booth at school with my parents.
I wish I was able to vote too.

The 39 Storey Treehouse

We are joining Andy and Terry in their newly expanded treehouse, which now features 13 brand-new storeys, including a dodgem car rink, a skate ramp, a mud-fighting arena, an anti-gravity chamber, an ice-cream parlour with 78 flavours run by an ice-cream serving robot called Edward Scooperhands and the Maze of Doom—a maze so complicated that nobody who has gone in has ever come out again … well, not yet, anyway. Well, what are you waiting for? Come on up!
Which storey would you like to go to and why would you like to go there?
