## 'All the Digits' printed from http://nrich.maths.org/

Use counters or scraps of paper with the digits $0 - 9$ written
on them.

Make a list of $3$ consecutive numbers $0 - 9$ remembering that
$3$ has already been accounted for.

What could the first figure of the product be if the
multiplication is by $3$?

Which consecutive numbers could be in the four-digit number?

Which other digit could appear in the four-digit number?
