For Maths group 1B has been learning how to Increase and Decrease numbers (Percentages), To Increase numbers you have to Multiply the top numbers by each other one would have a percentage next to it if you are learning how to Increase and Decrease  percentages, and after multiplying you divide it by 100.Then you add the number that has a percentage beside it, to the number you divided by 100. And that is how you Increase percentages. To Decrease numbers and percentages you have Multiply the top numbers by each other one would have a percentage next to it Just like how you did with Increase but the last part you always minus never add. Something we found interesting was that Increasing is almost the same as decreasing but instead you are just subtracting not adding.

For maths, we were challenged to create a presentation as a group to create word problems relating to Tongan Languuage 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, kilo, meters). I enjoyed this task because we get to learn about Tonga Language Week by using maths.

LI : How to divide decimal numbers, using algorithim

For our weeks learning towards math, we have been on the subject that focuses on decimal numbers using the four arithmetic operations, addition, subtraction, multiplication and division. In these exact same order we had learnt to do each one of these, but with decimal numbers instead of the basic whole number things, not only did this whole week of the summary facing to decimal numbers teach us the operations to these, but this has also taught us to always put the numbers in their correct place holding value such as tenths, hundredths, thousandths, ect, while guiding us on to be more fast in our working with only a week and a half to learn all these equations!

For our learning we had been learning about decimals and we have been learning how to do the calculus of multiplying two decimal numbers together! During the process of this insight to these types of equations, we have now the knowledge on how the method works towards multiplying two decimal places together, which was very interesting on finding out because its very basic, being very similar of multiplying two whole numbers together. We also found out that this was a very curious journey of learning because for most of the equations we were solving, was that instead of multiplying it bigger than the original number it would go smaller than the original numbers!

LI : How to Subtract decimal numbers using algorithm.

For this Maths activity we took a step up from the last lesson and the step up it was to learn how to subtract two decimal numbers together ! This activity is also very similar to subtracting whole numbers, because all that there is to minusing decimal equations together is that all you have to do is add a decimal point, to the given equation! Something we also learnt during this lesson is that you always have to line up all your decimal points and when subtracting, and the number you can not divide get crossed off and gets replaced with a number in the front of that number, which you have to subtract one from the number in front of the number you have to divide.

LI : how to add decimal numbers using algorithm

For this math lesson we have been continuing on to learn about how to do basic math with decimals like addition, subtraction, ect, but in this particular lesson about decimals we started off with learning how to add decimals together. To also do this task you have to sort out the place values of each number from tens, ones, tenths, hundredths, thousandths, and more, while everytime you add the chosen numbers you have to always start from the number farthest to the right working your way up to the left. Another thing to remember when doing this maths calculation is to always carry the ones to the correct place holders and a very simple trick to do this is to make your working out very neat and tidy, so it will be easier to look at and figure it out. Something I found interesting was we learnt how to add numbers using decimal points, and we learnt a rule while adding decimal numbers is that you always have to line up the decimal points with each other.

For Maths Group 1 has been learning about Cube and Cube Roots, Cubes numbers are numbers that have an exponent of 3. An exponent is a small number that goes on the right of a number. It shows how many times you have to multiply a number by itself. Cube roots are similar to square roots. The structure is the same but there is a 3 added beside the radical symbol to indicate that you are trying to identify cube roots instead of square roots.But instead of finding numbers that are multiplied by itself twice, you are finding numbers that are multiplied by itself 3 times. I found this task intresting because I learnt about what the differences of Cube and Cube Roots.

LI : How to identify the highest common factor.

For Maths Group 1 learnt about highest common factors and to find the highest common factor, you have to find what number is the highest common factor between two numbers, and we also learnt how to do prime factorisation. Common numbers is a digit that is the same in both numbers. Factors are numbers that when multiplied gives a product. I enjoyed this activity because I learnt the highest common factors for many numbers 

For Maths, Group 1 learnt about prime and composite numbers. We learnt the difference between prime 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.
