Elisabeth Fritzl taught kids grammar, language and math in cellar

London, May 21 : Austrian cellar mum Elisabeth Fritzl's lawyer has revealed that she taught her kids math and grammar while incarcerated in her dad's dungeon.

Her lawyer, Christoph Herbst told a Channel 4 documentary that the family lives a "more or less regular life" in the Austrian hospital where they have been kept since Josef Fritzl's secret dungeon was discovered.

"They rise at about six or seven in the morning. Then they have breakfast together, they get the breakfast from the hospital...Then they sit together at a large table and talk, discuss and make jokes," the Telegraph quoted him, as saying.

"Then everybody does their own thing. They play on the computer, they read books, do some drawings, whatever they want...It's very amazing to watch the family because they behave like a normal family," Herbst added.

He said: "Elisabeth tried to educate the children in the dungeon. They had lessons, they learned grammar, they learned the language, mathematics.

"So they have been raised very well, they are very well behaved...I think Elisabeth tried to give them a structure and a good life under the circumstances in the dungeon."
