The three big ideas

  • To buy a few things, add their prices to find the total cost.
  • When you pay more than the total, the extra comes back as change — use subtraction.
  • Plan ahead: check your money is enough before you buy.

Worked example. A clay pot is ₹40 and a toy is ₹35. You pay with ₹100. What is the total and the change?

Total = 40 + 35 = ₹75. Change = 100 − 75 = ₹25.

  • When one whole is cut into 2 equal pieces, each piece is a half.
  • When one whole is cut into 4 equal pieces, each piece is a quarter.
  • The pieces must be equal — uneven pieces are not halves or quarters.

Worked example. A chikki is cut into 4 equal parts and you eat 1. How many parts are left?

4 − 1 = 3 parts left, which is three quarters of the chikki.

  • Read the story and ask: am I joining, taking away, making equal groups, or sharing?
  • “In all / altogether” → add. “Left / change / how many more” → subtract.
  • Equal groups → multiply. Sharing equally → divide.

Worked example. 12 balloons are shared equally among 4 children. How many each?

“Shared equally” means divide: 12 ÷ 4 = 3 balloons each.

Common mix-up: read carefully before choosing. “How much is left” means subtract, even if the story also mentions buying many things.
