Today the Mars probe made a safe landing and so a new era of exploration has begun. Our school children’s children will be faced with the problem of an overpopulated earth.

I can imagine two possible solutions: either satellite dormitory towns above our towns or now that the Mars probe has safely now landed, then the possible life extending with us to another planet.

How interesting and thrilling it will make Maths.

All Montessori schools should extend the number cards for these large numbers and show that by counting the zeros we can change the large number to ones easier to handle by changing to powers of 10.

Extend the number cards using the same colours as the other cards.
