Homework Help

If you're anything like me, then formal methods for maths have changed a lot since we were at school! To help you with supporting your children's learning, I've put together some guides for how we are teaching them to do the maths at school.

 

As always, if your child isn't feeling confident with their homework, they should come and let me know as soon as possible so I can go through it with them before the work is due in.

 

I hope this helps! 

Maths Homework - Friday 18th January 2019

This maths homework involves expanded addition. Let's work through an example question:

 

526+321=

 

The first thing you need to do with this method is break the larger number down into hundreds, tens and units /ones, like so:

  500+20+6

 

Then, you do the same with the second, smaller number. Notice how I've added an addition symbol in front of the second number so it's clear what type of calculation we are doing:

 

  500+20+6

+300+20+1

 

See how we've stacked the two numbers directly on top of each other, so the hundreds, tens and units / ones all line up. Then, you draw a line (with a ruler!) underneath the second number. It's best to leave a small gap in case you need to carry any numbers over (we'll look at that later.)

 

   500+20+6

+300+20+1

________________

 

Next, starting with the units, you add the top numbers and the bottom numbers together:

 

   500+20+6

+300+20+1

________________

  800+40+7

 

Now you've got the segments of the answer you need to put them back together again to get the answer, which is of course, 847. 

 

Some calculations may mean your child needs to carry a number over from the units / ones column to the tens column. For example:

 

526+328=

 

You'd lay the question out in the same way, so it looks like this:

 

  500+20+6

+300+20+8

_______________

 

Of course, 6+8=14 so you leave the '4' in the 14 in the units / ones column and add the '10' from the 14 to the bottom of the tens column, like this:

 

  500+20+6

+300+20+8

_______10______

                 4

 

You then work out the rest of the question as normal. 

 

  500+20+6

+300+20+8

_______10______

   800+50+4= 854.
