I have just had Dd1 trying to explain it to me but i haven't the foggiest what she is on about.
She said say if i add 5 + 6 = 11, then i have to do 6 + 6 = 12. She said near doubles helps me remember that 11 is by 12.
I am confused and feeling very thick.
Justr came to type this and couldn't even remember what they were called so had to wake her up to ask her.
