LS2 Age graph

L.I: To plan and carry out statistical investigations 

For our activity we had to create a graph on a topic. Azatulah and I went around our class to find 15 different people. We asked them how old they were. The results were that there were 2 people out of 15 were 10, 7 people out of 15 were 11 and 6 people out of 15 were 12.

After gathering out data were created. We used a pie chart to find our results. We noticed that almost half of some of the LS2 students are 11, 12 was the second at 40%! We had 2 student that were 10 which was the least amount. Me and Leon predicted that most of the students were 11 which was correct!

Fraction, percentages and decimals

Fraction are equal pieces of a whole that have been divided.

Percentages are the ratio of a fraction of 100.

Decimals are numbers that share a value but is separated from a dot called the decimal.

Fractions has a numerator and denominator. The numerator is the amount of pieces the person have and the denominator is the number that the whole has been divided by.

Equivalent fractions are fractions that have the same value. Equivalent fraction example: 1/2 = 2/4

Improper fractions are fractions but the numerator is greater than the denominator. Improper fraction example: 2/4 = 4/8

To find a fractions of a set take a number like 24. Then try and find two thirds of 24. First thing to do is find 1 third of 24. So you do 24 divided by 3 which equals 8 (24 ÷ 3 = 8) Then you do 8 times 2 which equals 16 ( 8 x 2 = 16) . So then two thirds of 24 is 16. 

Statistical Investigation

 This week for Maths we had to find the average of each team of athletics day. 

First thing we did was find out how many points each team had in each class. Next we added those points to find each teams total points. Then we added all the points of each team and tried to find the mean (average) by dividing the total points by 9. 

A way of finding the mean faster is by using multiplication. 

Here's an example: If there is 2, 2, 3, 4, 5, 6 then do this. (2x2) + (3x4) + (5x6) = ???. If you're wondering on how to add this then do this is how. 2 x 2 = 4, 3 x 4 = 12, 5 x 6 = 30. Then add all these numbers up: 4 + 12 + 30 = 46. 46 is how much points a team got. 

This activity was hard because we had to figure out the answer ourselves without using the calculator or any type of thing to find the answer. I still had fun because of how much I improved on my addition skills to find out the answers.

Basic Facts Boxes

Today I did my basic fact boxes. I did the speed demon challenge. The speed demon challenge is a time challenge where you answer each question as fast as you can. Once all questions are answered you stop the timer. I did multiplication. I got 37 answers correct and 23 incorrect. I think I could’ve done better because I’ve learnt about multiplication for the past 4 years and I’ve tried to memorise it.

Sharing Knowledge

For this weeks Maths activity we partnered up with people and learnt about what they learnt about their struggle. I learnt about addition and subtraction and geometry. 

Addition is adding things up and subtraction is taking things away. My partner taught me how to use addition and subtraction in written algorithm. Written algorithm is a type of maths strategy that can be used for addition, subtraction, multiplication and division. 

During this session of learning about addition and subtraction, my partner taught me how to use place value. To do addition and subtraction, using the place value strategy you write a number and put each digit in the right value. Then you do the same with the other number then add them up. Obviously if there a 2 digit number in one of the values you have to give the 10 to the next value. 

Geometry is using 2d and 3d shapes. 2d shapes are a flat shape that has faces and corners. 3d shapes are shapes that have many faces, vertices and edges. I also learnt the only direction that 2d shapes go are up, down, left and right. The only directions 3d shapes go are up, down, left, right, front and backwards. 

My partner also taught me about different things that 2d and 3d shapes can do. 2d and 3d shapes can rotate to get a different image or angle of the shape. 2d and 3d shapes have a reflection. A reflection (in geometry) is flipping the shape the opposite way. I also learnt that 2d and 3d shapes can transform. Transforming is changing the position of the shape.

I think I was an alright teacher. My explanation wasn't that good when explaining about measurements but I think me explaining about time was good because my partner understood me. My partner was a good student and they were good teachers to me as well. 

Time

 Time can be told in lots of ways, here are ways on how to tell time. 

Analogue time uses hands to tell time. 1 hand counts the seconds, 1 hand counts the minutes and 1 hand counts the hours.

Digital time uses am and pm. Am means At morning and Pm means past morning. Midnight is am which mean the time should be 0000. Midday is pm which means the time should 1200.

24 hour time mainly uses zero's. The time starts at 0000 and ends at 2359. It also uses am and pm. 

Another way telling time is using fractions. Visualise a clock as a quarter (or a fraction). One piece is how far the time goes. 

Another way to tell time is using written algorithm. This is how it can be used: If its 10:37 and dinner is in 2 hours. Add 60 mins to 10:37 to make 11:37. Then add another 60 mins to 11:37 to make 12:37. That is 2 hours used. Now add 17 to 37 to make 54. That means dinner is at 12:57.

Building | Maths

Building is a job that uses measurement, counting and multiplication. 

Building uses measurement so it can measure the materials length and height. It can also be used to measure how much material the builder wants to cut off. 

Building uses counting to find the right amount of material the builders want on their building. 

Building uses multiplication to find how much material the builder needs.  If the builders mess it up it will be a waste of material and a waste of money. That is why they need to use multiplication, so that they can get an exact amount.

Builders need to use these types of maths to make the right building.

Basic Facts Boxes

Today I attempted the Speed demon challenge. I did multiplication. I got all my boxes correct and it took me 4 minutes and 32 seconds to complete it. I think I could of had a faster time but I’m alright with this and I was also lucky with my answers since I didn’t know some of the answers.

Comment Thread

A comment thread is an conversation where it can be found in the comment section. There is a comment thread below made for maths.

When commenting start with a greeting for example "Hi" or "Talofa". 

Next give some positive feedback for example "I really like the strategies you and your group were using to find out the answer to the question."

Then end it with an open question. For example "What other types of strategies can you use to solve a maths problem?"

Comment threading is a good way to have an conversation over something and use your own knowledge.

I did the speed demon challenge. The speed demon challenge is about answering Maths questions as fast as you can. I did this up to 5. It took me 4 minutes and 40 seconds to complete all of the Maths questions. I found this challenge really easy and I think I can do the speed demon challenge up to 10.

Strategies of Solving

For Maths my group and I answered maths questions. What we did was use as many different strategies to answer each question. Some of the strategies we used were number line, written algorithm and place value.

The first set of maths questions were addition and subtraction. The first question was 84 - 7. What we did was use different strategies for example splitting numbers. What we did with the splitting numbers was do 84 - 4 to make 80. From 80 I subtracted 3 to make 77 and that is the answer. 84 - 7 = 77.

The next set of maths questions were multiplication and division. The first question was 5x5. One of the strategies we were using was skip counting in 5's which means we went 5,10,15,20,25. 25. We already knew 5x5 was 25 so that was our answer.

I found this activity fun and difficult because I sometimes got confused on what to do on one of the strategies we were using but I still had fun doing it.

Subtraction

For Maths we learnt how to do subtraction using place value. Subtraction is taking away from a number. I know 186 - 143 = 43.

First I broke up 143 into place values (One hundred, forty and three).

Next I subtracted the ones from 186. 186 - 3 = 183.

Then I subtracted the tens from 183. 183 - 40 = 143.

Finally I subtracted 100 from 173. 143 - 100 = 43.

So that means 186 - 143 =43.

Subtraction using place value is kind of easy.

Basic Facts

Today I did division on the basic facts boxes. I did the speed demon challenge which is about answering questions quickly. This took me 5 minutes and 21 seconds to complete all 90 question. At the end I got 77/90. I think I did a good job answering the questions and I think I could answer the questions a bit faster.

Today I did the speed demon challenge on division. Speed demon is about answering all of the questions quickly. It took me 6 minutes and 54 seconds to answer all 90 division questions. My results were 71 out of 90. I found this challenge easy but because it took me a while to finish I think I can do this challenge quicker.

Reading large numbers

Reading big numbers is hard. To read big numbers like 547 829 316, start reading from the millions place value.

In the millions house there are three different groups. The hundred millions, the ten millions and the millions. Start reading from the hundred millions to the millions column, for example: five hundred and forty-seven million.

Next read the thousands house. In thousands house there a three groups too. Hundred thousands, ten thousand and thousands. Start reading from the hundred thousands to the thousands, for example: eight hundred and twenty-nine thousand.

Finally read the ones place value house. In the ones house there a three groups as well. The hundreds, tens and ones. Start reading from the hundreds to the ones, for example: three hundred and sixteen.

Then read all the numbers from the millions value to the ones value, for example: Five hundred and forty-seven million and eight hundred and twenty-nine thousand and three hundred and sixteen.

That is how to read large numbers.

Today I did the speed demon challenge on division. Speed demon is about answering all of the questions quickly. It took me 5 minutes and 30 seconds to answer all 90 division questions. My results were 78 out of 90. I found this challenge easy because the questions were time tables I knew in reverse.

Place Value

Ancient Egyptian numbers are a form of language. The numbers are written in objects. Each image/object represents a place value like the short ropes.

The short ropes represents the ones, long ropes represents the tens, coils represents the hundreds, the flower represents the thousands, A finger represent ten thousands, a frog represents hundred thousands and a god praising to the sun represents million.

Example: This is a picture of the flower that represents the thousands

To make a number using Ancient Egyptian, Egyptians used objects in specific order to make the numbers. For example writing 5,435, in the Ancient Egyptian numbers uses 5 flowers, 4 coils, 3 long ropes, and 5 short ropes. 

Basic Facts

L.I: To remember basic maths facts

I did Basic Facts Boxes. I did the speed demon challenge Up to 5. I had to fill up 10 Addition boxes. It took 4 minutes and 40 seconds. I got every single one correct.  This challenge was really easy.

Independant Activities

L.I: To practice independent activities.

Our groups started a rotation. The activities we attempted were Basic Facts Boxes, Drills, Abacus, and finding a group logo. For the drills I had to answer addition questions. I attempted the Up to 10 Speed Demon challenge on Basic Facts Boxes. It took me 8 minutes and 18 seconds to complete all addition Basic Facts Boxes. Some of these challenges were difficult but I was still able to finish some of them.

Name Worth

L.I: To know what my name worth

This week we learnt about our name worth.  Each letter in our name had a different kind of number worth. L=8 E=2 O=4 N=8. Next we had to add the letter worth together to create a new number. 8+2+4+8= 22. BUT the name worth needs to be a single digit number. SO, 2+2=4. My name worth is four.
