LI: To find, explain, and fix the error
This week I have completed another maths challenge called writing words. In this activity I needed to read the question carefully to find the math in it to help find the most efficent strategy. To solve this problem I used subtraction and addition. An example to solve this math is to add up all the works Ana wrote from week 1-3, and the answer should be 5343. Next, subtract the total amount of words (6000) in the narritive from 5343, and your answer should end up being 3667.
I enjoyed attempting this challenge because it helped learn to use the most effcient strategy to help solve math equations.
For math we needed to figure out how many handshakes there would be altogether if everyone in LS2 shook hands. There are 54 students in LS2 so the equation is 53x27, because if one person handshaked everyone they would have shook 53 students, and when you handshkae there are two people so I divided 54 by 2 which gave me 27. The answer to 53x27 is 1,431 and that's how I worked out this challenge.
I enjoyed attempting this activity because it helped me to get better at understanding the question and to figure out how to solve it.

This week we have been using the Olympic games to help us with our math. The fourth challenge was about the countries medal tallys. Since 1896 countries participating in the summer Olympic games have been creating their own all-time medal tally. Use the data from both charts to work out the top 10 medal winning countries. Create a graph to display this data. Include a comparison to NZ’s medal tally. Be creative with the data you choose to show. The more information you include, the easier it will be to analyse and draw conclusions. Hint you will need to add the totals from both charts together.
In the second blogpost it says 'Create a graph to display the data' which means to sum the top 10 totals. When I added the top 10 totals I ranked it from 1-10, So the top 10 countries are:
United States of America - 2673
USSR/Russian Federation - 1271
Germany - 788
Italy - 771
Great Britain - 770
France - 683
Republic of Germany - 625
Sweden - 561
China - 487
Norway - 457
I found this activity interesting because it help me expand my knowledge of addition.

This week we have been using the Olympic games to help us with our math. The third challenge was about a badmington racket. An Olympic Badminton Racket has approximately 25 strings in total. When these strings intersect they form squares. This means that there is approximately 250 squares on the racket. Take what you know about right angles to figure out how many right angles there are on an entire badminton racket.
To answer this question I used my multiplication knowledge and the main information. I needed to find out how many right angles there are on the entire badminton racket. Since there are 250 square and 1 square has four right angles, so that means the equation is 250x4=? To get my answer I started off with 4x0=0, next I did 4x5=20. After that, I did 4x2=8 and lastly I added the two from the 20 to make it 10. In total it adds up to 1000.
I found this activity interesting because it helped me expand my knowledge of angles.

This week we have been using the Olympic games to help us with our math. The second challenge was about Nastia Liukin. She competed in a gymnastics competion, which is judged with a point system. Nastia Liukin, an uneven bar champion scored a dissapointing 16.725, which put her in second place. Her opponent beat her by 0.001 of a point. The Bronze medal winner's score was a 14.975. I needed to figure out the gold medal winners score and how much Nastia scored over the bronze medalist.
For the first question I used my addition knowledge to help me find the answer. I found out that the equation for this question is 16.725+0.001=? In total the gold medal winners score is 16.726. For the second question I used me subtraction knowledge to help me find the answer. I found out the that the equation for this question is 16.725-14.975=? In total Nastia scored 01.750 over the bronze medalist.
I found this activity interesting because it helped me expand my knowledge of decimals.

This week we have been using the Olympic games to help us with our math. The first challenge was about Michael Phelps. We needed to figure out the average of every swim stroke it takes him to get 2 meters down the pool. Michael Phelps competed in 8 different events in the 2008 olympic games. That meant we needed to find out how many meters he swam for his gold medal. After adding up the numbers the total was 1500 meters. I then needed to divide that number by two because he swam 2 meters. The answer was 750, which means it Michael Phelps 750 strokes to get into the 1500m range.
I found this activity interesting because it helped me practise my long division skill.
LI: To recall our time tables faster
Today for maths we have recalled our multiplication knowledge by playing a game called Super Fingers. This is a game to see how well and how fast you can answer questions, by using dice.
The instructions of this game is that we need to write a phrase on a white board or piece of paper. Then you will need to roll 2 dice which we will multiply by, and the first person to call out the answer will take one of the letters out. The first person to have all of the letters rubbed out will win the game.
The process we did it in was similar to a netball game, draw, quarter finals, semi finals, and lastly finals. To run this competition smoothly we created a bracket which showed who will versus who. Our bracket was now even so later in the game we did a wild card who were Vayan and Micah.
In pairs we challenged each other to see who was faster at answering the questions. The winner would go against the winner from another person. Whoever wins goes up against another winner, and it will keep going until there are two people left, which would be the finals.
The two people facing each other in the finals were Afatia and Chris.
I enjoyed doing this activity because it helped me recall my multiplication facts, and answer them faster.

A math quiz tests you knowledge on how fast you answer and the strategies that is used. There are two math quizes and one challenge.
One of the quizzes uses fact families and addition/subtraction. The second quizz uses strand question (geometry, time and more). The challenge is a statistics challenge.
The first quiz tests the person on their basic facts. The person would be given a 20 questions that are realted to fact familes and addition/subtraction. That person needs to select the best answer for the question or what they think the answer is. The person needs to select an answer for all 20 questions.
The second quiz uses strand questions which is everything but basic facts. This quiz has 15 different strand questions. That person needs to select the best answer for the question or what they think the answer is. The person needs to select an answer for all 20 questions.
For the physical task a person needs to follow instructions and use materials to help complete the challenge the best they can. The person needs to find the accurate answer by the end of this task.
Making quizzes and challenges can help people learn about how much they know and how they can improve. It's also important to know different math types becaus it can help them learn more information to help make it eaier to answer hard math equations.

The second quiz is strand. This quiz uses meaurments, geometry and more. The third challenge is to test the persons knowledge on statistics.
Fact families is using all four operations (addition, subtraction, multiplication, division). This challenges a person to find out a certain number. Basic facts challenges the persons ability to use simple math strategies and their ability to answer the question.
Strand question tests the persons possibilities to answer exstra questions. Strand is every other math topic (geometry, statistics, and more) apart from basic facts and fact families.

Fractions is one whole object cut into equal pieces. Percentages is the number that is expressed as a fraction of 100. Decimals is the numaral system is the standard system for for identifying numbers.
Fractions have two parts. They are the numerator and denomenator. The numerator is the amount kept. The denominator is one whole divided. There are two types of fractions which are equvalant and improper fractions. Equvalant fractions are: ½, 2/4, 4/8, 8/16. Improper fractions are 5/4→1 ¼ which are mixed up fractions.
Percentages often identifyed by the percent sign, "%". Division is used when trying to find out a percentage. One question that uses division, fractions, and decimals is ¼ 149. Here is how to solve it: ¼ of 149 is 37.25% 149÷4=? 9÷4=2)-1, 40÷4=10, (100÷4=25, 37.251
Decimals mostly indentify integer and non-integer numbers. Also percentages can transfer into decimals. Example: 100÷4=25% 0.25, 100÷5=20% 0.2, 100÷3=33.333% 0.3.
Knowing how to use fractions, percentages, and decimals can help make it easier to figure out hard questions.
We have been learning about finding average group score and adding a data set. These include statistics.
When we were adding a data set we used addition and multiplication because these were the only operations we used the most. These made it easier to find the answer for most of the equations.
When we were finding the average we used multiplication instead of using reapeated addition. Example: Finding the average of 182 and 174 is when you divide it by how many numbers like 9 and then add them together (20.2+19.3). Knowing little division questions like 18 divded 9 can help answer bigger equations like 180 divided by 9 because it's the same thing just 10 times bigger.
It's easier to do addition, subtraction, multiplication, and division when knowing what statistics is and how to use it.
LI:To explore statistics investigation
This week we learnt two different things that other people learnt during the past two weeks. The two things I learnt from other people was converting measurments and geometry.
First, Chisa taught me coverting measurments. Convering measurments is to divided or multiply the height, width, and the length of something. When the number has been multiplyed the decimal point moves to right once (if multiplying by 10). If the number has been divided the decimal point moves to the left once (if dividing by 10).
Next, I taught Chisa about statistics and interpreting data. Interpreting data is the process of reveiwing data through some process. When collecting data you need to ask a question. Example: What is the likely hood of rolling a six. Then roll a dice about 100 times then make the recordings into a grapgh so people can understand the data.
Then, I explained what money is to David. Money is an item that is accepted as payment for good, services, and etc. NZ money works on a place value system. NZ money currently works on our 100's place value system.
Lastly, David explained to me about geometry. This topic includeds shapes, the relationship between shapes and the movements the shapes do. 2d and 3d. 2d shapes are flat that have faces and corners. 3d shape has many faces, vertices, and edges. Vertices are where the edges or side meet and edges are lines that help form a side.
I enjoyed this task because I was able to learn from others understandings, and I also learnt new skills and knowledge. I thought I did a good job at teaching because the people I taught was able to understand what I learnt.
LI:To share and discuss our understandings
Money is a item the is accepted as payment for goods and services. NZ money works on a place value system. NZ money currently works on our 100's place value system.
The NZ money have 5 different coins and 5 different notes. There are 10c, 20c, 50c, $1, and $2 coins. There are $5, $10, $20, $50, and $100 dollar notes.
Here is an example on how the system works. A person then they used up a $1.50 and a $1.70. How much does the person have left? This can be solved using place value. First add $1.50c and $1.70c together. 70+50=$1.20c. Then add $1+$1=$2.00. After that add $2.00+$1.20c=$3.20c. Then take away $10.00-$3.20=6.80.
Money can be shown in many different ways. It's importaint to know to use money because it helps people understand the value of money.
Math is used in many jobs. Jobs like: cooking, building, teaching and more. Some jobs might just use basic maths like addition or division.
In cooking math is important. Coverting is used to help covert the temperture. Also measuring is used to help measure the amout of a food that weighs or measure the millmeters using a measuring cup.
Understanding how to use math in this job is good because if not knowing it can make the food disgusting. Might make people sick.
