About the project

This 4-week project saw the students learn about organising an event —a school carnival — and finding out how best to make it turn a profit. They held discussions, saw related videos, attended a talk on organising an event, and conducted a survey. To showcase what they had learnt and also connect with real life situations, they invited parents to enjoy the fiesta.

Driving Question

  • How are 6-digit numbers added and subtracted?
  • How are addition and subtraction used in solving real life problems?
  • How is profit and loss calculated?
  • How must overheads be accounted for?


The project started with a discussion in class on what was needed to organise a fun fair. Planning involved watching videos, filling in mind maps, formulating strategies, gathering facts with the help of Aditi Ma’am, from the Business Studies faculty, and finally assigning roles and responsibilities such as game planners, accounts managers, and programme analysts.

Mathematics and Business Studies were in focus in the second week as students explored the financial implications of hosting a carnival — honing their calculation skills with 6-digit figures, and learning how costs and profits work in business practice. Role-play activities and a day spent interviewing shopkeepers also helped them see the importance of understanding profit and loss.

Once money concepts were clear, they moved on to planning the carnival games. The focus was on minimising costs and earning a profit. Students first spent time on researching the cost of items that were needed for the games, so that they could estimate the charges for playing each game. They also brainstormed to finalise the presentation and layout of the game kiosks, and decide what play money was to be used during the carnival.

Project Culmination

The final day opened with our invited guests — the children’s parents — watching slides of the project journey, and enjoying the welcome dance. Later, they collected play money and played carnival games for an hour. Speeches followed, with students thanking parents for the support they had received from them during the project. After the guests had left, it was time for profit calculation and reflection on the learning process.

Teacher Reflection

What I loved most about this project was the children’s ability to deal with complicated details and their willingness to go through the thought process that was needed, even down to planning how to make a profit. Students were able to come up with innovative cost-saving ideas, yet also protected the environment by adopting the four Rs (namely, Refuse, Reuse, Recycle and Replace). It was heartening to see the children use time management skills as they worked in groups, solving problems and planning the event. Even when there were differences in opinion, they were able to come up with amicable solutions. The students’ acceptance of their allotted responsibilities, inventive games, and efforts in managing cost, all reflected their thorough understanding of the premise of this project.
