if you have 4 mung beans and take away half you'll have 3 and a half and be a big fat hippy to boot

do it with chocolate?

here's 1 choc if I double it how many will you have

mummy has 2 chocs if I give you half how many will you have

every time he gets it wrong YOU eat the choc

the best way to get little ones to understand halves IMO

get a bar of chocoalte - mars bar or whatever
tell him to half it but you get to choose which half...
after a few goes you can be sure that he will make the 'halves' as equal as possible

DS2 likes to double and half raisins. Same principle - if he gets it right, he gets to eat them. We use them for number bonds too sometimes.

Well, of course, not individual raisins.....

what are number bonds?

popsycal Mon 29-May-06 20:30:11

19+1=20, 18+2= 20
etc

Do'nt quite understand this. Is this some fancy way of learning the 2 times table? If it is then you could buy one of those singy -songy tape things for car journeys, Drives you round the twist but all mine learnt their tables this way.

You mean numbers aren't magic???

Anyway, why not do 2 times table? Do they not do tables in France? Why not? They are bloody useful forever!

a good one for halving the bigger number....say half 16.....

just learn halves up to 10

then for 16 - you havlf the 10 (5) theb the 6(3)
add em up = 8
