Performing Aksharabhyasam involves the following steps:

1. Preparation: Cleanse yourself by taking a bath and wear traditional attire. Set up a clean and dedicated space for the pooja, preferably in a quiet and peaceful environment.

2. Invocation: Begin by invoking the blessings of Lord Ganesh and Goddess Saraswati. Light a lamp or candles and offer flowers, incense, and fruits as a mark of reverence.

3. Guru's Blessings: Seek the blessings of a respected guru, priest, or elderly family member who will guide the child during the ceremony. They will conduct the pooja and perform the rituals.

4. Writing the First Letter: The child is seated in front of a plate or slate containing rice or sand. The guru or elder then guides the child's hand to write the chosen letter or mantra for the first time. The child may write the letter with their finger or a writing tool.

5. Chanting and Blessings: During the writing process, mantras and prayers dedicated to Goddess Saraswati and Lord Ganesh are chanted. The child and family members participate in reciting these sacred chants.

6. Offerings and Prayers: Offer prayers to Goddess Saraswati and Lord Ganesh, expressing gratitude and seeking their blessings for the child's educational journey. Offer flowers, fruits, and other sacred items as a mark of devotion.

7. Distribution of Prasadam: Conclude the pooja by receiving the blessed prasadam from the deity. The prasadam is then distributed to family members and participants as a symbol of divine blessings.

It is important to note that the specific rituals and practices of Aksharabhyasam may vary based on regional customs and individual preferences. Consulting with a guru, priest, or individuals experienced in Aksharabhyasam will provide more accurate guidance and instructions based on your specific cultural and religious traditions.
