I think it says

    学びもののまとめをしよう
    生活のまとめをしよう
    事業と休みの区別をしよう

which are kind of preachy statements about how they should run the class.. Keep your learning stuff in order, keep your lifestyle in order, have a clear break between classtime and rest time. I'd assume that it's a left over from when the class was studying for end of year exams perhaps? Since the earthquake came at the end of a school year.
