For Tech we learnt about STEAM and I learnt that STEAM stands for Science, Technology, Engineering, Art, Mathematics. Our teachers name is Mrs Fefita and she is so kind and We have Mrs Fefita for STEAM. For tech we go to Tamaki college and at Tamaki college we have Cooking, STEAM and lastly Art. I enjoy going to tech because we get to learn how to do new things and we get to learn about new things.
LI : To calculate the mean, median, mode and the range of data
In maths we have been learning about Mean, Median, Mode and Range. In this photo you can see the range of what the different height in group 1, 2 and 3 there is a range of 20cm between the shortest and the tallest person and this helps us find what are differents of the tallest and the shortest person. 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. The mode is the number that appears the most in a set of data. 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. The Range is subtracting the highest number by the lowest number in a set of data
I found this task interesting because I learn what the averge of the tallest and the tallest person.
Square numbers are basically numbers that are multiplied by it self. For example: 6 is 6 x 6 not 6 x 2, because it would be incorrect. To find the square numbers ask yourself “what number times itself would give me this number?”. Another example of Square numbers is 8 . To solve it, you have to multiply 8 by itself. 8 x 8 is 64. So 8 is 64. Square roots are factors of a number that can be multiplied by itself to equal the number. For example, 36. The symbol (also called a radical symbol) shows that you need to identify the square root of 36. To find the square root of 36, you have to find which number, multiplied by itself equals 36. Ask yourself “what number times itself would give me this number. The square root of 36 is 6 because 6 x 6 equals 36. Another example, 144. What number can you multiply by itself to equal 144, 12. Because 12 x 12 equals 144. That is how you find the square roots of numbers.
I found this task intresting because I got to learn what is the differences from Square and Sqauare roots and i got to learn how to do Square and Square roots
Integers are numbers that are whole, and are not fractions. Integers can be positive and negative numbers, just as long as they are whole numbers. Adding integers is simple when you know the rules. When there is a minus symbol behind the number, that is a negative symbol. Negative numbers are less than 0. Here’s an example. -5 – -4. When you are subtracting negatives the minus becomes a plus, and the -4 becomes a 4. So the new question would be -5 + 4. Using a numberline can help. First, we start on -5, and we go up by 4. The final answer is -1. Here’s another example. 91 + -7 = ? To be able to solve this, we change the plus into a minus symbol. And the negative 7 turns into a positive 7. The question now becomes 91 – 7, which is 84.
I found this task intresting because I learnt about Integers addition and I got to learn how to do integers addition.
For this task we learnt about integers Division, The rules of integers division is similar to integers multiplication. A negative number divided by a positive number will always be a negative number. This is because a negative number x a positive number is a negative number. For example, -32 divided by 8 equals -4. This is because -4 x 8 is -32. A positive number divided by a negative number will always have a negative outcome, because a negative number multiplied by a negative number = a positive number. For example, 32 divided by -4 is -8, because -8 x -4 = 32. A negative number divided by a negative number is a positive number, because a positive number x a negative number equals a negative number.
I enjoyed this activity because I learnt how to do maths with Integers but also with division.
When doing decimal addition always make sure to keep the numbers aligned by the decimal point so you don’t get confused. If the if there aren’t numbers in every column you, can add a placeholder 0 to keep it in line. Start by adding the first numbers on the right side. Then, always remember to move the decimal point down. Then add the next numbers going from right to left. If any number is higher than 9 then add the first number from the answer to the next number in the sequence, adding it normally.

This problem is solved by using BEDMAS, this stands for: Brackets,Exponents,Division & Multiplication, Addition & Subtraction. This is the order to use when solving equations. First you must look at your equation and solve the problem within the brackets first. Then look for any exponents, in this equation there is none. Next look if there is any addition and subtraction, in this equation we have both, so we work from left to right in this case starting with subtraction. Then finally we have addition giving us an answer of 13.
I found this task interesting because I learnt how to do orders of operations and I got to learn what orders of Operations is.
For this task we learnt about Decimal Subtraction, When doing decimal subtraction always make sure to keep the numbers aligned by the decimal point so you don’t get confused. If the if there aren’t numbers in every column you, can add a placeholder 0 to keep it in line. Start by subtracting the first numbers on the right side. Then, always remember to move the decimal point down. Then add the subtract numbers going from right to left.
I found this task interesting because I learnt how to do Decimal Subtraction.
For this task we learnt about integers Multiplication, Multiplication is easy when you know the rules and what negative numbers are. Negative numbers are numbers that must have a lower value of zero. Like -1, -1 iss lower than 0. Negative multiplied by a positive number will always become a negative number. For example -5×5= -25 because when you multiply a negative number with a positive number it will always become a negative number. But when multiplying a negative and a negative it will always become a positive. For example -6x-6 will be 36. The answer will not be a negative because you are multiplying a negative number by a negative number.

Order of Operations are when operations like these + – x ➗ are used in order of BEDMAS (Brackets , Exponents , Division, Multiplication, Addition, Subtraction) To use BEDMAS, You do brackets first, exponents second, division and multiply is third (you solve from left to right), then addition and subtraction fourth (you solve from left to right). I enjoy doing BEDMAS because I get to learn how to do Maths with Exponents.
I found this activity interesting because I got to work with my group so we can all discuss about what we think it might be.
