Tekau objects

For maths in T4W3 we were suppost to make an animation to discribe what tekau objects look like . Our animation could be used in squares , circles or anything for an example . But the animation had to show 1 or 10 objects . The question that was mostly asked was what number do we use in normal maths ? The number that we use in normal maths is normally 10 or 20 ( I think that it is ) .
