Official method:

'Make Ten Strategy For Addition

Step 1: The first addend and what make ten?
Step 2: Write the number below the second addend
Step 3: The number below the second addend and what make the second addend?
Step 4: Add the rest to 10'

https://www.onlinemathlearning.com/make-ten-addition.html

The **** is an 'addend'???
 
8 + 2 + 7 is what it is going for, easier for kids to reach a round number like 10 and then add the remainder when first learning basic arithmetic. We do the same in the UK
 
It seems a very cropped picture from a series of questions.

It's just trying to teach kids to make 10s to make it easier.

The answer is 8+2+7 for what's written.

So you have 8 take 2 from your 9 to make 10 (they should have used like 6 or 5 not 9) then you can just add on whatever is left of your 9.


The **** is an 'addend'???

^ any number you're doing to add up
 
You make the first number a 10 by subtracting from the second number, then add them to get your total.

Why its easier, I dont know, but apparently its how they teach kids nowdays.

Probably why most people younger than me cant even do basic mental multiplication/division let alone percentages.


(Example from yesterday actually, person couldnt understand that the VAT paid on something at £100 is £20 but adding the VAT onto something that costs £80 doesnt bring the price to £100 :rolleyes:)

Substituting '8+9' to '10+7' is literally just common sense? Why overcomplicate it so much?

I don't see how its easier than explaining that 8+9 is the same as 10+7?

Cause they're 6....common sense for them still includes licking things they find on the ground.


You were more than likely taught the same way, make up a ten to make it easier.

That's why you see it as "common sense" you know the method but have no memory of being taught it.



Because you were 6 and too busy being inexplicably sticky

Actually no we were simply taught it as rounding up.

The whole terminology and everything they are using can only make it harder for kids to understand this.

Also as per the picture, no parent that was taught 'rounding up / down' will even understand what this is when their kids need help with it.

What terminology?

The basic maths term you a gown adult didn't know?



Just because that image is sooooooooo badly cropped and miss leading for the exercise it may as well have come from the daily mail.


This isn't your photo is it?

'Addend' and 'Make 10 to solve' were never part of any of my maths curriculum during the 90s. These are not universal mathematical terms and I do not believe this is taught in the UK even today.

Rounding is a totally different thing though.

That's an actual separate operation.

You'd confuse kids telling them this is rounding when there's no rounding happening .


(Roubded like your phrasing the answer would be 20)

8+9 = hard

10+7 = not hard (apparently)

Take 2 off the 9 then add to the 8 up to a 10 and then add the remaining 7.

I was taught to do it the other way.

8+10 then subtract the 1.

No, if you're given 8+9 to solve, you simply round 8 to 10 and subtract the difference from the 9 to get 10+7.

This is universally how this is taught to make mental addition easier.

Or the other way as Kindai does it. This is simple and easier to explain to 5 year olds than whatever the stuff in the OP is meant to be.

Walk us through how you in your head make say 7+8?

For me id probably go

2 from 7 to 8 to make 10, 10 plus the 5 fromt he seven makes 15 etc


It's trying to formalise that process.

I'm assuming your brain doesn't just give you a savant style answer you have to work

I have to google most of the kids maths as while I can work them out easily my methods are completely different to what they have to use. :cry:

My favorite maths teacher who sadly only had for 1 year would. I vite people up if they had different methods so the board would have say

Sophies solution
David's solution
Tom's solution

And you'd copy down all 3 or just the one that you wanted to use.
