My child is starting class this year to receive first Holy Communion.
What is the proper sequence of the sacraments. Since he has not
received the sacrament of reconciliation.

Your son should receive the sacrament of penance (confession) before receiving his first communion. For more on this see Should children go to confession before receiving their first communion?
