## Hands-on math: understanding multiplication

The other day we were checking if Nat knew the times tables. I never asked her to memorize them, so I was positively surprised when it turned out she knew most of the facts. Those that she did not know, she was able to calculate fast. With one exception and xceptions are opportunities to learn. So we sat down, took the Spielgaben sticks and checked if her method was correct or not (it was not) and why.
