hi absorbentghost,
unfortunately it will be no animation but a 2d image 
@OZ:
thank you - and regarding your english, it’s ok for me 
meanwhile…
it is only an idea, and currently i’m gathering information about “10” and thinking about a good perpective to transport the idea of the number that looks almost identical to our ‘real’ 10 clearly to the viewer.
also, there is a small addition written on the wall (II+II8=I0).
there will be some childs sitting around the teacher, one might count his fingers, another ones throws some coins (or other form of currency) in the teachers basket and others are staring on the wall with the written numbers. i like the idea of childs enjoying maths/numbers, perhaps because the teacher uses some fancy magic tricks while teaching. 
and here the explanation of the numbers:
I (1) =1
II (1+1) =2
o (3) =3
Io (1+3) =4
IIo (1+1+3) =5
8 (3+3) =6
I8 (1+3+3) =7
II8 (1+1+3+3) =8
0 (9 or ‘huge 3’ or 3²) =9
I0 (1+9) =10
