Multiplication With Decimals

LI: How to mulitply using decimals.

 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!

Subtraction Using Decimals

LI: How to subtract decimal numbers , using algorithms.

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.

Addition Algorithm – Using Decimals

LI: How to add decimal numbers, using algorithms.

 

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.

 

Subtraction Algorithm

LI: To subtract using algorithms.

Algorithm subtraction is a method used in maths to subtract large numbers. Subtraction algorithm, is in lined by its place value ( ones, tens, hundreds, and thousands ) it makes it easier for you if its lined up by its place values. For this task I explained how to do subtraction algorithm on a DLO, doing this makes it easier to subtract large numbers.

I enjoyed this task because it helped me learn how to subtract using algorithm more easier.

Place Value

For the first week of Maths we learnt about place value and the written algorithn.

First we had to learn the written algorithn and how to do it the long way, because we needed to know how to explain how we done it. An interesting fact is that you have to start with the ones, then the tens, and then the hundereds.

Next I had to learn the place value way and then we had to get to our work.

Lastly we had to do the long way first and then after we finished we had to do written algorithm the place value way.

I enjoyed this task because it was really fun to do.  I did well at this task because I had fun. I need to improve on nothing because I did my work properly.
