BRAMPTON–There are two things that are banned at Guru Tegh Bahadur International School – calculators in math classes and smartphones.

Tucked away in the corner of a Sandalwood Pkwy. strip plaza near a Metro grocer is one of the top scoring school’s on this year’s Fraser Institute Elementary School Report Card, which opened its doors in 2015.

Principal Sanjiv Dhawan believes smartphones distract students’ and teachers’ attentions and students – from kindergarten to Grade 12 – are required to keep their devices off and in their bags during class. As for calculators, students aren’t permitted to use them until Grade 8.

“Every calculation is done on the mind,” he said. “It develops the understanding and strengthens the mind.”
