Translation:Shulchan Aruch/Orach Chaim/50
50: Reason why the Mishnah of "Where are Their Places" is said.
1 It was established that one should study Chapter "Where are Their Places" and the Beraisa of Rabbi Ishmael after Parshas HaTamid so that one will merit to study every day Tanach, Mishnah and Gemara, for the Beraisa of Rabbi Ishmael is in place of Gemara since the Midrash is like Gemara.
