"Why don't they ponder over the Qur-aan?"
This is the complaint of Allah Ta'ala in the Holy Qur-aan to mankind.
The Qur-aan-e-Kareem has very deep meaning and in every verse of the Qur-aan is a unique message from Allah Ta'ala to His beloved creation. It is necessary for us to ponder over these messages and reflect on them.
Attached is a short aayaat of the Qur-aan with its translation. This could be pinned up on the masjid board for people to read, memorize and reflect.
