Nava Vision helps students to learn Math from very early childhood,as young as age 4. The methodology followed in Nava Vision makes the students understand the concepts in an easy way.As per the concepts present in Abacus, Nava Vision has divided them into 8 levels by arranging the concepts present in Abacus to make students understand them clearly.

**Levels of Abacus 1 to 8 Series** (8 Levels of Text Books and Levels of Work Books.)

##### Why Abacus to students?

- Abacus helps children to get familiar with numbers and in turn helps them to loosen fear in Mathematics.
- Abacus starts at very basic level by teaching the numbers, it adds foundation to Mathematical knowledge in tender age.
- Progressing to the higher concepts of Mathematical calculations, Abacus helps in enhancing the development of brain in early stages.
- Coming to higher concepts of Abacus, it develops imaginary and photographic memory in kids.

During this course, Nava Vision teaches Abacus to students by providing the following:

- Trained Teacher: Well trained teachers are provided by Nava Vision,to teach Abacus for students.
- Abacus Tool: Abacus Mechanical Calculator / Abacus tool which is required to perform the calculations will also be provided to students during this course of time.
- Textbooks: Depending on the Level the student is subscribed to, the respective textbook will be provided to students during this course.
- Workbook: For each level, students will be given relative workbook of Abacus which facilitates the students to practice the concepts in a better way, which in turn helps them to get better understanding.
- Online Videos: Each level of Abacus will be provided with Abacus online videos, which can be accessed online through our official website www.navavidya.com.
