Objective: To practise the four basic operations on large numbers in a real-world scenario
and to experience how estimation can be used to check the reasonability of calculated
answers.
Materials required: Worksheet of ‘The Budget Director’ (provided by teacher), pencil,
eraser, ruler for drawing a table.
Procedure:
Imagine you are appointed as the Budget Director of a city’s annual ‘Fun Fair’ and
you have been given a starting budget of ₹75,00,000.
Your task is to calculate the total costs of rides, stalls, prizes, staff salaries, etc. and
check if the total expenses stayed within the budget.
On your worksheet, draw a table with four columns: Item, Calculation, Estimated
Cost and Actual Cost.
estimate Costs: Before calculating, round off the numbers for each item below and
fill in the ‘Estimated Cost’ column.
• rides: Renting 18 different rides, with each ride costing ₹1,25,000.
• Food Stalls: Setting up 45 food stalls, with each stall costing ₹32,000 for materials.
• Prizes: Buying 5,000 small toys for prizes, with each toy costing ₹95.
• Staff salaries: ₹11,80,000 (fixed).
• Marketing: Advertising costs of ₹8,15,500 (fixed).
Calculate Actual Costs: Now, perform the exact multiplication for the Rides, Food
Stalls, and Prizes. Write the calculation and the result in the ‘Actual Cost’ column.
The costs for staff salaries and marketing are fixed.
Calculate total cost (Addition): Add all the numbers in the ‘Estimated Cost’ column
to get a total estimated cost. Then, add all the numbers in the ‘Actual Cost’ column
to find the total actual cost of the fair.
Find the Balance (Subtraction): Subtract the total actual cost from your starting
budget of ₹75,00,000 to find out how much money is left over, or if you went over
budget.
