GATBO NHS

Gatbo National High School joins the community in mourning the passing of Hon. Leslie Demdam, former Barangay Captain of Gatbo, Bacon District, Sorsogon City.
We remember "Kap. Leslie" for his years of dedicated leadership and the foundation of support he built for our school and students. His presence in every school activity and program was a testament to his dedication; he didn’t just govern from a distance, he worked alongside us to ensure our students had every opportunity to thrive. We will forever be grateful for his generosity, his helping hand in times of need, and the genuine kindness he showed to every teacher, parent, and student. His legacy of service and his heart for the school community have left an indelible mark on Gatbo NHS.
While we grieve this great loss, we celebrate a life well-lived in the service of others. Your kindness will never be forgotten.
Our thoughts, prayers, and deepest sympathies go out to the Demdam family and loved ones during this time of sorrow.
May his soul rest in eternal peace.😔🕊️🙏🏼

A proud milestone achieved!

Our Grade 12 GAS students have successfully defended their research during the Final Defense held on March 9--a testament to their dedication, perseverance, and academic growth.

This accomplishment would not have been possible without the guidance of their research adviser, Sir Reymart Bustamante, and the insightful expertise of our esteemed panel members: Sir Esmeraldo Fulgar, Sir Milven Estrada, and Dr. James Christian D. Nabong.

With the strong support and supervision of our school head, Sir Markson B. Mejia, this event stands as a celebration of excellence, collaboration, and the pursuit of knowledge.

Congratulations, researchers! Your hard work has truly paid off. 🎓📚✨

International Day of Mathematics (also known as Pi Day) is celebrated every March 14 around the world. 📐➗

Why March 14?

It is celebrated on March 14 (3/14) because the date represents the first digits of π (pi) = 3.14, an important number in mathematics used to calculate the circumference and area of circles.

Who Proclaimed It?

The United Nations Educational, Scientific and Cultural Organization (UNESCO) officially proclaimed the International Day of Mathematics in 2019 to promote the importance of mathematics in science, technology, engineering, and everyday life.

Purpose of the Celebration

The day aims to:
• Encourage interest and enjoyment in mathematics among students.
• Highlight the role of mathematics in innovation and development.
• Show how math is used in daily life, science, engineering, and technology.

Gatbo National High School joins the Celebration of International Math Day through conducting interactive, fun and stimulating activity. This year’s School-based Math Day Celebration has the theme “Math in Motion-Thinking, Creating and Innovating”. The highlights of the event include Grade Level Quizbee, e-modulo arts contest, Poster Making Contest and Math Showcase.
