Summary
Chapter 10 of the Class 2 Maths NCERT textbook (Joyful Mathematics), "Fun at the Fair", teaches children how to add and subtract money using rupees and paise through fun fair activities like buying tickets, playing balloon-popping games, and making different combinations of coins and notes.
- Spending and Finding Change at the Fair — Rupal visits a fair with ₹50 from her mother and spends most of it on rides. Children learn to subtract the money spent from the total to find out how much is left.
- Counting Up to Find How Much Was Spent — Rupal's friend uses a counting-up method — starting from ₹8 left and adding ₹20, then ₹20, then ₹2 to reach ₹50 — to find she spent ₹42. This teaches an addition-based way to solve subtraction problems.
- Indian Currency — Notes and Coins — The chapter introduces commonly used Indian currency notes (₹100, ₹200, ₹500) and old coins (10 paise, 20 paise, 25 paise, 50 paise). Children also learn that 100 paise equals 1 rupee.
- Pop the Balloon Game — Addition of Money — Matru plays a balloon-popping game at the fair where each balloon carries a different rupee value. Children practise adding the values of 3 or 4 balloons to find the total prize money won.
- Making Amounts in Different Ways — Children learn to make the same amount using different combinations of ₹1, ₹2, ₹5, ₹10, ₹20, and ₹50 coins and notes, and practise word problems involving buying items with a given amount of money.
