Weekly blog post

This week on Monday we did sports athletics on Tuesday we did Hymns on Wednesday Library, Music, Assembly in assembly we did a poster competition and it was also World Ocean Day. On Thursday we did arrays and square numbers. On Friday we finished our square numbers post and we had art.

Arrays

Hi my name is Jonathon. Something that I found out that was interesting  with arrays was that when you do arrays it is a another way to do multiplication. So I am going to do a example of what I mean. Lets start twelve times twelve. So we have twelve groups with twelve in it. Then we add them all up together witch would equal one hundred and forty-four. When you put it into arrays you put twelve groups with twelve in them. This is a picture of what it looks like when you have  finished your array. This is an even number. I know that it is a even number because the number that I multiplied it by was a even number. And I will tell you this an odd number plus a even number equals an odd number and a even number plus an even number is a even number and an odd number plus an odd number equals a odd  number.

Square Numbers

Square numbers are arrays that are the same number on each side.

hht This is 11 by 11 which has 11 on each side.

Also if you added an odd number to an odd number the answer has to be a odd number, it’s exactly the same if you added a even number & a even number together it’s an even number.

But if you added an even number with an odd number the answer is always even.

 

square numbers Andre

Today we learnt about abut square numbers our teacher Mr C told us to do 1 to 12 square numbers it looked hard the first time then it got easier when we kept doing it here is some did. These are 2 6by6 we learnt that there’s a pattern that goes odd even odd even. A square number have to be like this 1by1 2by2 3by3 4by4 5by5 6by6 etc.you can do arrays up to 15. You can make arrays with square counters like what I have just done. It’s just doubling the number you multiply.

 

 

that’s the way that I know about square numbers WIN_20160609_10_30_36_ProWIN_20160609_10_27_48_Pro

Understanding square numbers with Melanie

WIN_20160609_11_30_45_ProThis morning in class we learnt about arrays and square numbers with Mr C.  What I learnt about arrays was when you multiply it makes it easier to do it with arrays.  Say if you have a sum 4✖5 then you do four rows of five.  Or if you had the turnaround sum 5✖4 then you do five rows of four.  What I found really cool about square numbers is that to make a square number it has to be doubled by the same number.  Say you have 9✖9 that is a square number so then you use your arrays and do nine rows nine and that equals to 81

Arrays

WIN_20160609_10_32_51_ProToday our class 4M have been understanding/learning about Arrays being helpful in Times Tables, Arrays are helpful because groups and numbers work together to make an Array, ok so lets say 5×5=25 now there will be 5 groups every group has 5 numbers in 1 group it would look like this, so basically as you can see there is 5 groups and each

⬛ ⬛ ⬛ ⬛ ⬛  group has 5 numbers inside of them count each of the

⬛ ⬛ ⬛ ⬛ ⬛ squares and you have the answer 25 if you want

⬛ ⬛ ⬛ ⬛ ⬛ to know more keep reading!Another thing is if you multiply in odd numbers the answer will be a odd

⬛ ⬛ ⬛ ⬛ ⬛ number for example 3×3=9 and none of those numbers are even example is 4×4=16 it’s not even it’s

⬛ ⬛ ⬛ ⬛ ⬛ odd the tens house is number 1 and that is not even the other it is but that doesn’t count because only the 10 house does if the sum is multiplied by even numbers lets say 2×2=4 then the answer will be even.

Hey guys

This is the what my class did this week,

This week in class my  we have been learning about division and today we were doing the square times tables and they are when you time the number by the itself.One of the patterns that I found was that it is odd, even then it keeps doing that till it ends.Another thing is that if you are doing it you need to always make the number have the same amount on each side.

Hear are some rules:

If you are doing an array

  • you need to make it in a square and that means that it should be the number in rows and columns
  • it can be in any number you like

hear are some tips for you:

  • there is only one square in the number
  • it is odd ,even, odd and so on

You can do these any where and with many diffract things.here is an example this is an array of 9×9

you can do this for Division or multiplication
