Two pages of the Daily Missal give a very good (and concise) explanation of the parts of Mass. I've included them as images below, but I'll reproduce their content in prose.
|Our Participation in the Mass|
|Parts of the Mass||Our Participation|
|1. Prayers at the foot of the altar.||WE COME to Mass longing for God and with great sorrow for our sins.|
|II. Prayerful Worship|
|WE LISTEN to the word of God in the Epistle and Gospel and respond with the Credo, "I believe."|
|III. Sacrificial Preparation|
|1. Offertory Verse.|
2. Offertory Prayers.
3. Washing the Fingers.
4. Orate Fratres.
5. Secret Prayers.
|WE ARE PREPARED to offer God that sacrifice which is most pleasing to Him, self-surrender.|
|IV. Sacrificial Action|
|1. Preface and Sanctus.|
2. Memento of the Living and of the Saints.
4. Offering of the Victim.
5. Commemoration of the Dead and petition for Communion with the Saints.
|JESUS CHANGES our gifts into His Body and Blood. We offer Him and He offers Himself with us and for us to His heavenly Father.|
|V. Sacrificial Banquet|

2. Agnus Dei.
4. Communion Verse.
|THE FATHER GIVES us His Son in Holy Communion. We abide in God and God in us.|
|1. Ite Missa Est.|
3. Last Gospel.
|WE GO AS children of God with Jesus and like Jesus to our work.|
The other page, titled "PLAN OF THE MASS", uses the structure of a church building as its context for the parts of Mass. You'll need to look at the image for the full effect; here is my translation of the image:
I. MASS OF THE CATECHUMENS

3. GLORIA (Praise)

1. EPISTLE or LESSON
II. MASS OF THE FAITHFUL
