Curriculum

Abaku is arithmetic for the 21st century

The curriculum for individual age periods of a child establishes adequate tasks and recommends activities from the Abaku START methodology to accompany them. Our curriculum is continuously supplemented with new activities as they are professionally tested. The recommendations are based on the experiences of educators and their didactic knowledge.

First period 5-8 years

• Can read, write, order, and compare them.
• Uses equality and inequality signs.
• Works with zero.
• Recommended activity: Abaku balls.
