Why Number System Matters in ICSE Class 6

$Number System isn't just Chapter 1 — it's the foundation for everything else you'll study in maths. Place value helps you understand decimals. Estimation helps with mental maths. The Indian and International systems come up again in data handling and word problems.$

$ICSE exams test application, not just memory. You'll see questions that mix numeration with real-life contexts — population data, distances, money. Practising with this worksheet gets you ready for exactly those types of questions.$

$Once you're done with Number System, move on to Integers or HCF & LCM to keep building your skills.$
