How To Make a Bar Graph.

                                         How to make a bar/ column graph.

By following this step by step guide you will be able to make a bar graph.By knowing how to create a bar graph it can help present and understand information clearer.

You will need:

  • Ruler
  • Data
  • Pencil
  • Paper

Method steps:

1. First collect your data so you have information to put in your graph.

2. Draw a horizontal and vertical lines that join on the left hand corner.

3. When you have drawn the lines on the vertical line label the numbers 0 to 50. Place 0 at the bottom and place 50 at the top.

4. After that label your data underneath the horizontal line.

5. Once you have labeled the horizontal you start your bars. You draw them to the number of objects you have.

6. Then finally you collar in the bars.

Finished bar graph.

 

mathsmate problem 22

Prediction: I predict this will be about adding blocks.

Clarify: Nothing to clarify.

Question: The question is asking how many blocks are in the whole block total.

Answer: First you count the blocks you can see and then work out the number of blocks that you can’t see. Then you get 17 blocks.

Summary: I think this was a challenging question but you can solve it in the end.

BTN Reflection

This weeks BTN was about a massive model train set in Canberra. When I watched the video of it there was a full scale model of the set. There were hundreds of trains on it from steam trains to high speed trains. They also explained of the children who come here and are very happy to go to the train model expedition. When I saw the video I was shocked of how big it was and how many trains were running on it at the same time. So that was my reflection on my BTN I hoped you enjoyed it.

Mathsmate problem 22

Prediction: I predict that this will be about how many cubes are n the big cube.

Clarify: nothing to clarify.

Problem: the problem is how many cubes are in the cube.

Way to work out: First you add the cubes that you can see. Then you count one of the 4 by 4 squares again and then count 2 of the big cube parts again.

Answer: When you finish adding all the parts you get your answer, 104

Summery: I think this question was quite tricky but in the end it is easy to add up in the end.

International day of the girl

On the 11th of October every year the 11th day of October is the day of the girl. The reason this happens is because hundreds of girls in the world don’t go to school and don’t get to learn. So every year every single school do the international day of the girls. There is one thing I don’t under stand still why do the do this to them when they should treat them like boys instead of doing things you do later in life instead of doing them straight away in life instead then take it slow and steady. Right now I still don’t understand why the world dose this to girls. It is very strange.

Infographs

Infographs

Q: What is an infographic?

A: A visual image of data.My A: A visual program which you make graphs and data on

Some of the problems we encountered along the way were

A: Trying to get the graphs working.

What we did to over come these were

A: Work as a team and work quicker.

What worked with our infographs was

A: Was doing the work and not slacking.

What I can improve upon is

A:

Below are our graphs

Holiday Reflection

During the holidays I learned two things which was to use a schedule to organize all of my things. I also learned to play proper Basket Ball with only five people and to work as a team in games and not to get annoyed when you don’t get a goal.

When I was organizing my things during the holidays I didn’t just plan every thing to do in just two days. For example I went to watch the football on Saturday then I went to Luna Park on Sunday for the day!

Also another thing I learnt during the holidays was not to get a bit mad when you are playing a team sport and the other team gets all the goals. because when I came down to practice Basket Ball some of my friends who play the game were there and we played a match, but we almost lost because the other team was smashing us and on the inside I started getting angry. So those were the two things I learnt during the holidays

Maths Reflection on 2D and 3D shapes

2D + 3D shapes: Properties and connections

Near the end of term three we all started learning more about 3D and 2D  shapes. Some things we learnt about them were the Length, Width and Depth and those are some of the most important things we learnt about 3D shapes.  We also made some 3D shapes out of 2D shapes and it was quite tricky to do. For example we had to measure all of the parts of the shape and then to make the actual shape itself. Before I started learning more about those key points about 3D shapes I hardly was an expert on it but I know some things about it but now I know lots about it.

Some things I know about it is all the shapes what to use to make them and lots of other things about 3D shapes. Also another thing I learnt about was what congruent means which means it is the same width, length and depth.

Notes into Summaries

In term three we did projects on Australians involved in medical or scientific research or human rights.When each group presented we took notes, here are the summaries from my notes.

Professor David Craig

In 1919 a man called David Craig was born. In 1944 he became a teacher and then he became a scientist in 1946 in Australia. He studied Physical chemistry, Carbon Dioxide and urain dioxide which are all made up of certain acids.

Bary James Masshall

James Masshall was born in 1951 and worked on medical medics to get rid of tummy oysters which are tummy infections. In 1980 he started working at a hospital to help with infections like tummy oysters.

Abigale allwoon

Abigale was born in Melbourne and during her childhood she was fascinated in fossils and she sent the first robot onto mars!

Sir Marcus lours looklent

Marcus studied the atomic bomb but he studied it during the world war so the Americans used it agents the Japanese. When the bomb was dropped it took 35 seconds to hit the ground and if there was any one close to it would disintegrate or become blind.

Professor Marten Terer

Marten studied the stem cells that are in the human body and they change into normal cells.

Dan Cate Camble

Dan was born in 1899 and was a scientist and retired in 1976.

Andy Thomas

Andy was the only Australian Astronaut to go to the moon. He also sent a robot into space and there are miths in space like U.F.O’s and aliens on mars, Marshons and so on.

Isolel Eliza Toom

Eliza Toom was fascinated in marenbiolgraphy during her childhood. When she was older she rote 10 books based on the great beerier Reef and the sea.

 Greame Clark

Greame made the bionic ear to help death people who couldn’t hear at all. He also became rich after his work was put into shops to help people hear again. Also at the age of ten he became fascinated in people who were death or couldn’t talk at all.

Professor Andrew White

This last one I will talk about is the one I did. Professor Andrew was  a Scientist who worked at Quantum physics.
