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.

 

Data Analysis

For this research assignment we had been given the task of reating a DLO explaiining how we analysis the data which had been created by LS2 ourselves and the topic for our data was ‘ Why LS2 are Absent ‘ leading to sickness being the highest/main reason why we don’t come to school while the lowest reason was ‘ I Don’t Like The Teacher’ which is a very bad reason to be at school ! I found that this was a cool assignment to do!

Highest Common Factors (HCF)

LI: How to identify the highest Common factor.

For number knowledge in maths, we have been learning how to identify what Highest Common Factors are. How to do this task you would need to use your multiplication skills (calculator), and find all the factors of the two numbers , after this you need to find the highest common factor out of both of these numbers for e.g ; 12, 24’s highest factor is 12 because if you multiply 12 by 2 it would equal to 24 therefore being the HCF ! Also during this lesson we also learnt how to do prime factorisation because it connects to HCF and also because recently we had been learning prime numbers ! I liked learning this and  I also can’t wait to learn more things !

Prime and Composite

For this activity we have been learning about Prime and Composite numbers, this helps us tell the difference between Prime and Composite numbers. What helps us tell the difference between a Prime and Composite number is that Prime numbers are numbers that can be divded by 1 and itself, therefore Composite numbers are numbers that can be divded out evenly (mostly likely end with 2, 4, 6, 8, 10 and so on). The only even prime number is 2 because a prime number is a whole number greater then 1 that has only two factors (1 and itself). I enjoyed learning the difference between Prime and Composite because it was challenging at first but then once I got used to it I enjoyed how fun it was.

Camp Food Budget

LI: To understand a budget is a plan for managing money.

In our camp activity groups we were given a budget of $2,000 to feed and hydrate everyone. We chose a menu for breakfast, lunch, dinner and snacks for morning tea and deserts. We used our smart searching skills to find the best price for the food we wanted. The maths strategies we used were multiplication. working in groups helps me understand because it gives a better understanding from each other and it helps us get a small idea created into a bigger idea. Something I enjoyed was working together in my group because we collaborated and got to know each other more better while we were at camp. 

Camp Cabin Maths

LI: To use our knowledge of basic facts, to solve a problem.

For maths we have been learning about maths, and a thing we were doing for our maths was the organisation of it like the cabins and how much came to camp. We used our basic facts knowledge to solve how the issue of how many students in one cabin. The strategies we used were addtion because it helped us get how much of girls and boys there were, and how many of students there were altogether. Something we found interesting about working out the word problems was that we could all fit into 5 cabins because of how big our class is. I learnt it is important to use my own strategy because it lets me get a better understanding of what happens. 

Creating a math game ( Sneaky Santa )

L.I: To design a Math game

L.I: To collaborate with others to design and create a maths game.

For this activity, we were challenged to create a Math game. Me and my group decided to make it Christmas themed, so we had pick up cards with the Grinch and Gifts on it. Our whole group contributed and participated in creating the board game and making the cards. We used cardboard to create our Sneaky Santa 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 Algorithm

LI: To calculate the difference of  whole numbers, using algorithms. 

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.
