Learning number bonds?

[Rosebud05]

Just received pages and pages of reception home work for dd....

Mentions number bonds, which despite being ancient, I understand what they are but have no idea how to teach them.

I remember someone posted some songs and websites - would anyone mind filling me in to save trawling back through old threads?

TSMIA

To the tune of Barney's sickly sweet "I love you, you love me, Oh how happy we could be" (Is it the same as Knick Knack Paddy wack?)

One and Nine
Two and Eight
Three and Seven,
Counting's Great
Four add six,
Five add Five
Six and Four
Let's count some more
Seven and three
Eight and two
Nine and one
We're almost done
Ten add zero
Zero add ten
We know our number bonds to ten.

Playing dominoes is good.

Also, try telling your child that 1and8 are friends but 1 and 9 are best friends, as are 2 and 8.....when two best friends are added together they always add to 10.

10 lego or duplo bricks, play a game of splitting them in as many different ways as you can, write the different combinations on a white board with a pen[much more fun than pencil and paper]

Good luck

9 and 1 are number bonds
8 and 2 are friends
7 and 3, 6 and 4
5 and 5 are twins

Basically it's the unit numbers which added together make 10

Also using Lego or something similar, but using a LOT more bricks (of just TWO colours, if you have enough) lay them out so the pattern can be seen of one colour INCREASING while the other colour DECREASES. Lay them down, or build up like steps.

So:

ten of one colour none of other
nine of one colour one of other
eight of one colour two of other
seven of one colour three of other

etc, etc

then of course, the sides are equal at 5 and 5; after which the colours 'swap over' as to increasing/decreasing.

(sounds awful I know, Sorry; pity can't do coloured text on here, but I'm sure you can work it out!.)

Funny, I can see our little multi-coloured towers of lego blocks from here. Really made it visible for DD.

We did number bonds in the car, repetition over and over works. Plus making it 'real' i.e. If I had 10 apples and Daddy ate 3 how many are left...

I taught my dd's using Nickys song using the tune of 'row row row your boat'.
It's catchy and easy for them to remember.

The actual concept (rather than just 'rote') can be taught by using 20 objects - 10 of one kind and 10 of another. It can be anything you want, or that your child is interested in.

Smarties/skittles work fine. 10 yellow and 10 red. 9 yellow and 1 red make 10, just as 9 red and 1 yellow make 10. 8 yellow and 2 red make 10 ...etc ...

Hi Rosebud5:

Some nice addition games here for reinforcing number bonds: www.maths-games.org/adding-games.html

and some nice resources for addition/ subtraction here: www.primaryresources.co.uk/maths/mathsC1.htm

BBC Learning [BETA] - has some nice worksheets here: www.bbc.co.uk/schools/teachers/keystage_1/topics/maths_counting.shtml - have to scroll down a bit - but start from one more games about half way down. Also see adding to ten worksheet here: www.bbc.co.uk/schools/teachers/keystage_1/topics/maths_calculating.shtml

Funky Mummy games (to 10 or to 20) are good: link here www.woodlands-junior.kent.sch.uk/maths/interactive/

There's a nice marble game where you shoot a marble (with a number 1-9) toward the right marble with the number to make 10 (and the hint number is always behind the gun): www.akidsmath.com/mathgames/addtoten.htm

Some nice at home games are to pour out a box of smarties or raisins and count then play adding up games with random amounts - you get to eat them all if you're correct. Also good to do it in reverse - so start introducing subtraction. Nice to reinforce the visual once the concept is understood by have your DC write out the sums (horizontal is fine - that's what they'll be dealing with in Y1 anyway).

A game to stretch them (so to really work out all possible sums 1-9 + 1-9 and beyond is here: www.sheppardsoftware.com/mathgames/fruitshoot/fruitshoot_addition.htm (I'd advise doing this once they really have sound knowledge of adding +1, +2, +3, etc...
