Double Century
The chapter 'Double Century' in Class 3 Mathematics introduces students to numbers beyond 100, taking them all the way up to 200. Building on their previous knowledge of single and double-digit numbers, students learn to read, write, and count 3-digit numbers using placeholders like hundreds, tens, and units. They explore cricket scores, skip counting, number names, and grouping items in hundreds and tens. This foundational chapter is very important for the Gujarat (GSEB) board exams as it builds strong number sense and prepares students for advanced arithmetic operations like addition and subtraction in later classes.
