Make me another number game!

So, real live schooly learning is happening, but we haven't called it that yet. It's playing numbers. Me and my new laminator are making worksheets with number games; I'm going to rope Daddy in for the shapes one. Counting, writing numbers, reading numbers, linking counted items to written numbers, place value...

I can't work out how to do place value without some tools. Rods, bricks, that sort of thing. I must find a source.

Oh - and the name of the number 0 is "Zero-nothing." I find this almost as cute as "The dark is brilliant, isn't it, Mammy?"
