Run the Plover Flat Water Department: A Budget Game

A grade 4 budget game where teams run a fictional town's water department for two years, funding operations first and learning why savings matter when a main breaks.

Objectives

  1. Students will build a department budget that funds required operations before optional projects.
  2. Students will explain why a water department keeps savings even in years when nothing breaks.

Vocabulary

Water main
A big underground pipe that carries drinking water beneath the streets to a neighborhood. Smaller service lines branch off it to reach each building.

Also: budget, trade-off, emergency fund

Teacher overview

In this simulation for teams of four, each team is the water department of the fictional town of Plover Flat for two pretend years. The rules do most of the teaching, because the budget sheet requires teams to pay for daily operations before they fund any optional project, and a pipe break revealed partway through the game leaves the teams that set money aside in a better position than the teams that spent everything. Students finish with a working sense of trade-offs and of why a town's water bill pays for more than the water itself. You need one budget sheet per team and a single event card you keep hidden until the event step, right after year one.

Activity Directions

  1. Set up before class: print a budget sheet per team and a handout per student, and keep the event card hidden. Write the price list on the board: run the treatment plant, 400 water dollars; pay the crew, 300; paint the tank, 150; new park drinking fountain, 50; new well survey, 100; pipe repair fund and savings, any amounts the team chooses.
  2. Introduce the game (10 min): in our scenario, the town of Plover Flat hands each department 1,000 water dollars for the year. The plant and the crew are must-pay cards, because a town cannot skip cleaning water or paying workers. Whatever remains may be split among projects, the repair fund, and savings. Every water dollar must be assigned somewhere.
  3. Year one (10 min): teams fill in the budget sheet so the amounts total exactly 1,000, must-pays first. Ask each team to read its plan aloud in one sentence.
  4. The event (10 min): reveal the event card: a water main breaks under Cedar Street, and repairs cost 250 water dollars, payable from the repair fund and savings together. Teams that can pay mark the break repaired. Teams that cannot must cancel a chosen project to free its money, and any team still short must borrow the rest from next year's budget and note the debt on its sheet.
  5. Year two (10 min): the town grants a fresh 1,000 water dollars, minus any debt. Teams rebuild their budgets with what they learned. Most teams grow their repair fund; let them say so out loud.
  6. Debrief (10 min): ask what each team gave up to be ready for the break, name that a trade-off, and ask why a water department saves money even in a calm year. Close by noting that real towns budget this same way for pipes, plants, and crews, then have students complete the numbered handout questions.

Answer Key

  1. Answer: 700 water dollars. The two must-pay cards cost 400 + 300 = 700.
  2. Answer: 300 water dollars. Starting from 1,000, the leftover is 1,000 - 700 = 300.
  3. Answer: 50 water dollars. The repair fund and savings hold 100 + 100 = 200, and the break costs 250, so the team is short 250 - 200 = 50.
  4. Answer: 150 water dollars. The raise is 1,150 - 1,000 = 150.
  5. Answer: Because breaks arrive without warning and must be fixed fast, since homes need water every day. Money saved in calm years pays for the emergency without canceling projects or borrowing.

Differentiation

Support (below grade level)

Give these teams a budget sheet with the two must-pay rows already filled in and totaled, so their choices start from the 300 remaining. For the handout, allow a number line or hundreds chart for questions 1 through 4.

Extension (above grade level)

After year two, hand these teams a second event card you invent on the spot, such as a drought that adds a 100 water dollar cost, and have them balance the year in writing without borrowing.

ELL supports

Pre-teach budget, trade-off, emergency fund, and water main with icons on the price list: a plant, workers, a paintbrush, a fountain, a piggy bank, and a broken pipe. Let teams state plans with the icons, and accept short phrases on handout question 5.

Extensions

Invite students to ask an adult what surprise repair their own household or school building once faced, then write two sentences comparing that surprise to the Cedar Street main break and telling how saving ahead of time helped or would have helped.
