Home Schooling, Early Years: NUMBERS, Adding 1 'In Your Head' Using the Numbers' Poster

We are still doing additions only.  The idea is to build up on one principle before moving on to the next, to avoid confusion.  Numbers is O's favourite 'subject' at the moment: finally similarities with big sis!

However, I've been trying to think of the ways to teach him mental additions. He can do 1+1 and 2+1 and then he gets stuck most of the time.   I've noticed that he doesn't know things like 'what's a bigger no, 5 or 6?' I suppose why would he. (Crazy how many things we take for granted).   Although I love cards, the simplicity and versatility of them, it seemed easy to have something in one piece to avoid laying it out every time.  So we got a poster.  In fact we kind of binge shopped and got few of these posters in Bracknell Discovery centre, I'm sure we'll make some use out of them all!

With this lovely poster, we are now trying to explore the idea that 'each next number is bigger than the one before' , bigger by 1 , to be precise, and so instead of counting out 6 counting sticks to add 1 , he can just go to the next number up in his head.  Hopefully it will work.  Will update!
