This is an idea I used with my children a couple of Ramadans ago.
It is an activity which can be enjoyed by all ages throughout the month, inshAllah. As the plates were made we stuck them on the walls, so that by the time Eid arrived we had a brightly decorated room!
We used paper plates and reference books containing hadith and ayat about Ramadan, fasting, Lailat al-Qadr etc. Every day we would choose a hadith or ayat to study, then the children would copy it out onto the paper plate, and decorate it with craft materials, paints etc. One of the children was too young to write out the hadith, so she decorated words like “Ramadan”, “fasting” etc instead.
We used plates to symbolise the idea that when we fast we are filling plates with worship rather than food.
