What number am I? I have two digits. I have no ones. I have a nine in the tens place.

We know the number has two digits. So I’ve drawn two digit cards to represent those two digits. This card would represent the tens digit. And this card would be the ones digit. So we can give this box a check because we’ve read it and we’ve drawn our two digit cards.

So this number has no ones. So the ones digit would be a zero. So we can check this speech bubble because we’ve written our ones digit on our ones card. The final speech bubble tells us that there is a nine in the tens place. So we can check this speech bubble because we have drawn a nine in the tens card. So the number is 90.
