“God wrote the universe in the language
of mathematics.”
- Galileo Galilei
Mathematics may not teach us how to add
love or minus hate but it teaches us that
every problem has a solution.
“Only in the world of mathematics do two
negatives multiply into a positive.”
- Abby Morel

A FEW IMPORTANT REMINDERS : 1. Homework and correction work needs to be done on a regular basis.
2. Children must bring the materials for class activities (eg. straws, cut-outs etc.)
when informed by the teacher.
3. A neat folder should be maintained for keeping the worksheets.
4. Notebook work must be followed up.
5. Regular revision of classwork must be encouraged in children.
