All the Bais Yakovs & Chadorim got it wrong.

All the Bais Yakovs & Chadorim got it wrong. For the next few weeks, all Bais Yakov Schools and Chadorim will be teaching the little children, Hagada Shel Pesach. Most children will be able to sing, translate and memorize  the 10 מכות. The הגהות מיימוני writes the reason R. Yehudah gave the siman of דצ"ך עד"ש is because Dovid Hamelech in Tehillim (78 & 105) mixed up the order of the מכות. R. Yehudah gave the siman for the מביאי ביכורים to say it in the proper order.   The Chasam Sofer writes the reason why the order in Tehillim is mixed up because there is a סכנה to verbalize  the מכות) נזיקין) Therefore, except for ליל שמורים, the order of the מכות are mixed up, to mix up the צנורות (pipelines) so no harm will come from saying it. The Ch.Sofer continues that for this reason when teaching children we should mix up the order of the 10 מכות. Only at the Seder night should they say it in order. The way to memorize the proper order should be with the siman of דצ"ך עד"ש  Perhaps since none of the schools & Chadorim follow the Chasam Sofer's advice and do teach it in the proper order there is no danger in doing so because of 'שומר פתאים ה. Chazal tell us if the masses do something foolish & dangerous, Hashem protects the fools. אמבצי
