There are 6 pillars (articles of faith) that a Muslim must believe in:
- Allah
- Allah's Angels
- Allah's Books
- Allah's Messengers
- The Last Day
- Allah's Decree, the good and bad of it
- “Iman is to believe in Allah, His Angels, His Books, His Messengers, the Last Day, and to believe in the Qadar and what it brings of good or bad.” (Saheeh Muslim)
Reference
AbdurRahman.org's Imaan Links - Salaf us Saalilh/Abdurrahman.org is my first go-to site for Islamic studies reference/reading material, alhamdulillah.

It has general works on eemaan (belief), links to works on the increase and decrease of eemaan, as well as works on each of the six pillars of eemaan.Explaining Faith - "written with simpler language while avoiding topics that may not be suitable for younger readers.0" (Taken from works of Shaykh Uthaymeen)

Reading and Vocabulary Drill Sheet for Definition of Eemaan
I love flashcards, but have the darnedest time keeping up with them. So I try to make up reading and drill sheets to drill vocabulary.
With this particular sheet, students can practice reading the various words that make up the definition of eemaan, according to the hadith of Jibreel (alayhi salaam). Then, they can also be quizzed on the English meanings of the words.
