TLW – Word Problems

For maths, we created a presentation as a group about word problems for Tonga Language Week. We made the problems out of  a topic or Tonga items. We had one word problem each on each slide, some used Tonga groceries, Tonga items, lolly lei etc. In the word problems we included equations (+, x, -, divison, kilometers, meters). I enjoyed this task because we get to learn about Tonga Language Week by using maths.

Highest Common Factor

LI: How to identify the highest common factor.

For Maths, Group 1 was learning about Highest Common Factor. A highest common factor is the largest number that divideds two or more numbers, numbers can be multiplied to make another number. An example is, the factor of 10 are 1,2,5,10 because 1×10 equals 10 and 2×5 equals 10 which is the same answer but a different equation. eg; factors of 12 is 1,2,3,4,6 and 12. Factors of 18 is 1,2,3,6,9 and 18. The common factors are 1,2,3 and 6. The highest common factor is 6 because it can divide large numbers and another way is multiplying the common prime factor together. I enjoyed doing this because we get to learn about highest common and get a better understanding.

Prime and Composite numbers

LI: How to identify prime and composite numbers.

For Maths, Group 1 learned about prime and composite numbers. We learnt about the difference between prime numbers and composite numbers; Prime numbers are numbers that can be multiplied by 1 and itself and Composite numbers are numbers that can only be divided evenly (it has other multiples than itself and 1). An example of a prime number is 17 can only be divided by another number because the number 17 has only two factors which are 1 and 17. A composite number is 22 because it has more than 2 factors which are 1,2,11,22. This led us to making a DLO explaining what the difference between prime and composite numbers is and adding examples/questions. I enjoyed doing this because it helps us understand the meaning. Something I learnt when learning about this equation is, a factor is a value that can divide a number evenly.

Long Divison

Long division is a way of dividing a big number by a smaller number and finding out the answer, which is called the quotient. The important part in long division is that the strategy is divide, multiply, and subtract. Youstart off by writing the divided on top of the line and divisor below the line, divide the first digit of the dividend by the divisor and write the result below the line, multiply the result from dividing the first digit and subtract the equation from the dividend, bring down the next digit of the dividend and repeat the steps over again until you reached the end of the dividend. The final result is the quotient (answer) and the remainder (left over).

I enjoyed learning about long divison because it teaches me how to fix problems step-by-step and break them down into smaller parts.

Creating a Math Game (Sneaky Santa)

LI: To collaborate with others designs and create a math game.

For this activity, we were challenged to create a Math game. Me and my group decided to make it Chirstmas themed, so we had pick up cards with the Grinch and Gifts on it. Our whole group contributed and participated into creating the board game and making the cards.We used cardboard to create our sneaky sanrta sign, and the board game itself. We covered the cardboard pieces with paper and added designs onto it.

 

Rules

  • When you land on a box that has either Grinch, Gift, or Santa, you pick up the card that you landed on. For example, when you land on the Grinch, you pick up the card that has a Grinch on it. 
  • If you pick up a grinch or a gift, you have to answer the math problem. If you get it wrong, you have to go back 3 steps. But if you get it correctly, then you are safe and you don’t move. 
  • If you land on the Grinch’s house, you’re in jail. To get out of jail, you have to roll a six.
  • When you pick up one of the Grinches, you have to keep it with you. To win the game, you have to get the least amount of Grinches when all of the Grinches are gone.  5

Subtraction Algorthim

What is subtraction algorithm? Subtraction algorithm is a way of subtracting one number from another. It’s like where you follow a few simple steps to get the right answer. Algorithm is a use of a combination of borrowing and subtracting to find the difference between two numbers. For example, we want to subtract 457 from 935. 5- 7 = -2 (borrow 10 from the tens place). 5 + 10 = 15, then subtract 7 = 8. 3 (tens place) – 5 (tens) =-2 (borrow 100 from the hundreds place), 3+10=13, then subtract 5 = 8. 9 – 4 = 5. So the answer is 478.

I enjoy how the subtraction algorithm helps me break down big numbers into smaller.

3D shapes – strand

LI: How 3D shapes are defined.

3D shapes are shapes that have 3 dimensions, length, width, and height. Properties of shapes are what shapes own. Like: faces, edges, and vertices (corners). For this activity we drew 3D shapes in our strand books, and wrote its properties. An example for this is : a circle has 0 faces, 0 corners, and 0 edges.

I enjoyed this task because I learnt about the properties of lots of 3D shapes.

Algorithm Addition

We was challenged to use addition algorithm to solve addition problems. On my DLO it shows an explanation on how to solve addition algorithm. When doing algorithm addition it is important to remember to carry the 1 if the number is bigger than 9 and place it to the next column. As you can see above my DLO it shows why algorithm addition is important to learn.

I found this task fun and interesting because knowing how to solve addition problems when using algorithms is easier to use than other strategies.

Place Value

LI: To explore numbers (written, expanded, numerals).

For maths we are learning about place value and in this DLO we are showing our understanding and what Place value is. As you can see, in each column there are millions, hundred thousands, ten thousand, thousand, hundred, tens, and ones in each box. Underneath it shows examples about what it looks like.

I enjoyed this task because it helps me understand what a place value is and where it belongs.

Statistical Investigation

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

Our maths group created a bar graph which shows all of the students’ cultures. We used our skills to find out the data of where their grandparents are from, from LS2. We put these cultures in order from most to least. The most culture in our classroom was New Zealand and the least was Tuvalu and Thailand.

I enjoyed this activity because it tells me more about our classroom cultures.
