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.

The first two sentences are too blurry for me. I think the third (left-most) sentence is:

○ 授業と休み時間の区別をしよう

"Let's distinguish between class time and break time."
