PYTHAGORANS Week 5

Tuesday

After a really successful time last week, and it definitely showed through in your test results, I think we will stick with looking at Khan Academy to support our learning.
Today we are building our knowledge of factors, as you guys seem to need a little support in this area.

LI to check if large numbers are divisible by 2,3,5,6,9,10

I would suggest watching some of the video and then trying out the next one without Khan giving the whole game away.

Divisibility Tests for 2, 3, 4, 5, 6, 9, 10: Worked example of basic divisibility tests


Write down the steps that you need to take to work out whether large numbers are divisible
Step 1: Is the number even at the end, 0,2,4,6,8 are all even numbers, even 0! If they are even you know that the number is divisible by 2.
e.g 5,670 - 0 is an even number!

Step 2: Add the numbers together in large number
e.g 5+6+7+0= 18 what can this number be divided by?

And once you have completed that,
please try out these examples using lattice multiplication

1. 347 x 258=
2. 295 x 140 =
3. 1,350 x 2,380 =

LI find factors of a number
This is linked in to yesterday's exploration of divisibility, where we could figure out what large numbers are able to be divided by.

Definition before we start:
A factor is a whole number that fits evenly into another whole number. For example, 3 is a factor of 9, because you can fit 3 evenly three times into 9: 3 x 3 = 9.

Okay so in your books show all of the factors of 160

Long Division



More long division and remainder examples: More long division and remainder examples

Okay, so we are looking at long division. Which is not as fun as lattice multiplication which I am a massive fan of, but it is still a beautiful piece of mathematics, and helps us to actually understand what is happening when we divide numbers.
