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.

LI : To collaborate with other 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 Honey themed, so we had pick up cards with the Grinch and Gifts on it. Our whole group contributed and participated in creating a digatial  game and making the slides. We used our chromebooks to create our Honey Bug name, and the digitial game itself. We made our slides, decorated it and animated the slides. Our Instructions for our game is

The Range is subtracting the highest number by the lowest number in a set of data. For example: “Find the mode in the following data set” 1, 8, 4, 23, 5, 6, 8, 3, To find the range, you have to multiply the largest number by the lowest. First step, order the numbers from the smallest to the largest number.  1, 3, 4, 5, 5, 6, 8, 8, 8, 23.  Seeing from the organized data, you can tell that the largest number is 23. So you do 23 – 1, which is 22. So the range of this data set is 22.

I found this task interesting because I got to learn range is subtracting the highest number by the lowest number in a set of data.

The mode is the number that appears the most in a set of data. For example: “Find the mode in the following data set” 1, 8, 4, 23, 5, 6, 8, 5, 3, 8. To solve this, you have to see which number appears the most. First, you order the numbers from the smallest to the biggest. Then, you can determine which of the numbers is the mode. 1, 3, 4, 5, 5, 6, 8, 8, 8, 23.  From the listed numbers, you can see that the number 8 is the mode because it is the number that appears the most, with it showing 3 times.

I found this task interesting because I got to learn what ode is in maths.

The Median is the value in the middle of a data set. To find it, you just have to figure out the number that is the the middle of an organized data set. For example: “Find the median in the following data set, 3, 2, 7, 12, 5, 8, 9”. First, order the numbers from the smallest to largest number. 2, 3, 5, 7, 8, 9, 12. Now, you find the number in the middle. Which in this case it 12. But if there are two numbers in the middle, add them together and divide it by 2. For example, 3, 2, 7, 12, 5, 8, 9, 0. Once again, order them from the smallest to the biggest.  0, 2, 3, 5, 7, 8, 9, 12. The median in this data set is 5 and 7. Since there are 2 numbers as the median, you add them up and divide by 2. 5 + 7 = 12, and 12 divided by 2 is 6. So the median in this equation, is 6.

I found this task interesting because I go to learn why median is the value in the middle of data set.

For we learnt what about mean ,The mean is the average number of a data set. To find the mean, you have to add up all the numbers in the data set, and divide it by the amount of numbers there are. For example: “Find the average in following numbers listed” 3, 2, 7, 12, To answer this equation, you have to add up the numbers.  Eg. 3 + 2 + 7 +12 is 24. Next step is dividing 24 by the amount of numbers. Since there are 4 numbers in the data set, you divide 24 by 4, which should give you 6. So your answer is 6. Can you solve the mean for the next one? 9, 18, 3, 5

I found this task interesting because I got to learn the mean of a average number.
