3D Shapes

LI: the name and properties of 3D Shapes. LI: label 3D shapes

Our task was to name, label 3D shapes and find an item that we use everyday that is a 3D shape. For example: A sphere has 1 face and 0 vertices because a sphere is round and has no edges. An everyday item is a ball, that we use to play basketball, football, dodgeball and many more. A cube has 6 faces and 8 verticies. An example of an everyday item is a rubix cube.

I enjoyed this task because I learnt the details and how to label 3d shapes.

How to do Subtraction Algorithm

Subtraction is a way to find the difference between 2 numbers. An example is: 254 – 124=. The first step is to start with the ones column so 4-4=0. Then move on the tens column which is 5-2=3. Lastly the hundreds, 2-1=1. The answer is 130. Tip: You can borrow 1 from the left column next to the column you are in. It is important to keep everything aligned when doing the algorithm.

I enjoyed this because I helped others on how to do subtraction.

Mean, Median and Mode

LI: to find the mean, median and mode.

Our task was to find the mean, median, and mode in our blog posts throughout the years in Pamure Bridge School. To find the mean add up all the numbers in the group. Then divide the total with the amount of numbers there are in the group. Median is the middle of a arranged list of numbers. To find the median put the numbers in order from smallest to biggest and find the number in the middle. If they are two numbers in the middle, add them together and divde them by 2. The mode is the number that shows the most is the mode. To find the mode put the numbers in order from smallest to biggest and look for the number that shows up the most in the list.

I enjoyed this task because I learnt how to find the mean, median, mode and I also saw the progress I have made throughout the years in Panmure Bridge School.

Statistical Investigation

LI: To read the text, gather sort, graph and analyse the data

Our maths group created a diagram which shows the top six rivers in Auckland from smallest to largest. We used our collaborative skills to find out the data of each river. We put these rivers in this order from shortest to longest and we used our knowledge to come to the conclusion on what river is the longest out of the 6 rivers in Auckland, which is the Wairoa River at 65 kilometers in length.

I found this activity amazing because my group had a given role in this task and we worked together to find out the conclusion which was the longest river in the Auckland region.

 

 

Basic Facts Challenge

Today we started our basic facts boxes challenge. The purpose of this challenge is to help us increase the speed when working on equations with large numbers.

My time today was 4 minutes and 36 seconds. My goal for next time is to finish 4 minutes and under. To achive this goal I will need to press the right keys and practice more.

Tempurature

I learnt how to read the tempurature and see how long it takes to change from hot water to cold.

First we filled up the sink with hot water and put in our thermometer which was started at 42 degree celsius.

Then we put in some ice packs and went to check on it every 5 minutes. On the 20th minute it stop at 26 degree celsius and from there on it stayed at 26 celsius. The tempurature stayed at 26 celsius because it was the coldest the the sink tap can go.

I enjoyed this task because I learnt how long it takes to change from hot water to cold. I did well at checking on it every 5 minutes. I need to improve on finding out why the tempurature stopped at 26 celsius.

How to make a Marble Maze

Once you follow these steps you will know how to make a marble maze easily.

Materials:

  • A4 size cardboard
  • Straws
  • Marble
  • A4 size paper
  • Scissors
  • Ruler
  • Chromebook

Steps:

  1. Open a slide and make a table 7 horizontal and 10 vertical.
  2. Place your in and out
  3. Place your lines and traps black
  4. Turn the grey lines to white
  5. Print the maze onto a A4 paper
  6. Glue the your maze onto the A4 cardboard.
  7. Glue the straws onto the black lines
  8. Grab the marble and enjoy.

 

Time

Time can be used in seconds, minutes, hours, and many more. There are different types of clocks such as analog and digital clock

To tell the time on a analog clock is that you need to see where the minute hand, hour hand, minute division, hour division, and sometimes the second hand. On a clock the time is counting in fives. The minute hand is the long hand and the short hand is the hour. The minute divisions are the little dots and the hour divisions are the numbers on the clock. If the hour hand is on the 3 and the minute hand is on the 12 then it is 3 o’clock.

Time can be used to see how fast something can go.

Marble Maze

I learnt how to make a marble maze.

First I needed to draw seven horizontal lines and ten vertical lines.

Then I needed to figure out where the in and out is going to be. I also needed to figure out different ways to go from in to out.

Lastly I made my maze only and I needed to put in traps to trap who ever is doing my maze.

I enjoyed this task because I learnt how to make a maze. I need to improve on making traps. I did well at figuring out different ways to go from in to out.
