May I suggest you have a look at the concept 'Let's visit Numberland'? Might not sound super innovative, but it is very different from other Numberland ideas, research project based, and has become a standard approach here in Germany, while increasingly finding friends in other countries, especially the UK.
'Let's visit Numberland' is all about the core story that our number friends live in a place, well, called Numberland which we PHYSICALLY build on the floor/a table: A (geometrically shaped) garden for each number, with a house, a flag, a tower, a flowerbed, an earthworm - plus other things the children find match the number. To get there, we must manage Number Lane forward and backwards. It's an open, co-constructive approach, using a lot of moving around, role-play, co-construction, stories, songs, activities etc.
The concept started in Germany 2004 as a highly perceived research project; I joined after experiencing the huge impact it had on my children and their peers, and became co-author in 2011. Ever since, I have been accompanying further projects and promoting the concept also internationally - just because it's such a powerful, beautiful, natural, and child relevant approach.
Also teacher relaxing, because all the good things happen within this structuring, yet open frame - language, too (first, second). Just came back from a training at the German school in Mexico City and also travelled to Numberland with the children - no language barrier whatsoever with the Spanish speaking little ones!
Hopefully, this is an inspiration. Feel free to get in touch. I could also put you in touch with schools in the UK using Numberland. There is an English handbook and several resources, but the website might just be sufficient already.
