⚓ DeckhandHarbor Earnings judge 80/100Bloom L2🪙 50 earned

Join Skye on an adventure to earn money by doing chores and dockside jobs around Harbor Cove!

Objective: Learn how to earn money · Standard: CEE Standard 1.2: Income and Earnings

📖 Skye needs to earn some money for a new fishing rod, but first must figure out the best way to do chores around Harbor Cove.

Q1: If Maria helps her dad load crates at the dock and he pays her $10 for 2 hours of work, how much does she make per hour?
  • $5
  • $6
  • $7
  • $8

💡 Maria makes $10 in total over 2 hours. To find out what she earns each hour, divide the total amount by the number of hours.

Q2: Skye does 3 chores at home. She earns $4 for washing dishes, $6 for mowing the lawn, and $5 for feeding the chickens. How much did she earn in total?
  • $10
  • $12
  • $13
  • $15

💡 Skye adds up all her earnings from each chore to find out how much she made in total.

Q3: Juanita earns $3 for each boat she cleans at the marina. If she wants to buy a new hat that costs $18, how many boats does she need to clean?
  • 4
  • 5
  • 6
  • 7

💡 Juanita needs to earn enough money by cleaning boats. She should divide the cost of the hat by her earnings per boat.

Q4: If Carlos earns $20 from fishing for a day and he spends half on snacks, how much money does he have left?
  • $5
  • $10
  • $15
  • $20

💡 Carlos keeps the other half of his earnings after spending on snacks.

🎣 Stand CaptainBait & Tackle Stand Boss judge 80/100Bloom L4🪙 50 earned

Welcome to Harbor Cove! Test your skills running a bait and tackle stand.

Objective: Learn how to run a successful business while exploring the harbor! · Standard: CEE - Financial Decision Making

📖 Skye needs your help running her new bait and tackle stand in Harbor Cove. She has lots of fun challenges for you.

Q1: You have $10 to spend on supplies. How much will you have left after buying 2 packs of lures at $3 each?
  • $4
  • $6
  • $5
  • $7

💡 You need to subtract the cost of lures from your total money. It's important to keep track!

Q2: If a customer buys one pack of lures for $5 and pays with a $20 bill, how much change do they get?
  • $14
  • $15
  • $16
  • $17

💡 Change is what's left after you subtract the cost of an item from the money given. You should count it carefully!

Q3: You want to save up $30 for new supplies. If you earn $5 each day, how many days will it take?
  • 6
  • 4
  • 5
  • 8

💡 You need $30 and earn $5 each day, so $30 ÷ $5 = 6 days. Dividing a goal by what you earn each day tells you exactly how long to plan for!

Q4: Skye bought 10 hooks for her stand. She sold 7 of them at $2 each and spent the money on new lures that cost $4 each. How many lures could she buy?
  • 3
  • 5
  • 4
  • 6

💡 Skye earned 7 × $2 = $14. Each lure costs $4, and $14 ÷ $4 = 3 lures with $2 left over. In business you can only buy whole items — the leftover $2 stays in the cash box!

🦪 Patient PearlOyster Bed Treasures judge 82/100Bloom L3🪙 50 earned

Learn how planting oysters can turn small savings into big treasures at Harbor Cove!

Objective: Explore · Standard: CEE: Saving and Investing

📖 Skye, your friendly guide in Harbor Cove, shows you how to turn a little money into a big treasure by planting oyster beds.

Q1: If you put $50 in the bank today and it doubles after one year, how much will you have?
  • $25
  • $100
  • $75
  • $50

💡 When your money doubles, you get the same amount again. So $50 becomes $100.

Q2: If you save $10 every month, how much will you have saved after 6 months?
  • $50
  • $70
  • $60
  • $80

💡 Saving $10 each month for 6 months means you add $10 six times. That's $60 total.

Q3: If you earn $2 for every oyster harvested and harvest 4 oysters, how much do you make?
  • $6
  • $10
  • $8
  • $5

💡 Earning $2 per oyster and harvesting 4 means you multiply $2 by 4. That's $8 total.

Q4: Which of these is a good way to save money?
  • Spend all your coins
  • Put some in a piggy bank
  • Give it away
  • Exchange for candy

💡 Putting money in a piggy bank is like planting an oyster bed; it grows over time!

🧭 Change ChampHarbor Market Math judge 82/100Bloom L2🪙 50 earned

Get ready to count coins and dollars in Harbor Cove! Skye will guide you through the market adventures.

Objective: Count and make change · Standard: CEE Jump$tart standard J-4.1

📖 Skye needs to buy fresh fish at the Harbor Cove market, but first she needs to know how much money she has.

Q1: If Skye has $1.25 in her pocket and finds a quarter on the ground, how much does she have now?
  • $0.75
  • $1.50
  • $1.25
  • $1.00

💡 Adding the values of each coin gives you the total amount.

Q2: Skye wants to buy a fish for $2.50 and has three dollars in her wallet. How much change will she get back?
  • $0.75
  • $1.50
  • $0.50
  • $3.00

💡 Subtract the cost of the fish from the amount Skye gave to find out how much she gets back.

Q3: If Skye has 2 dimes and 3 nickels in her pocket, how many cents does she have altogether?
  • 20 cents
  • 35 cents
  • 30 cents
  • 25 cents

💡 Two dimes are 2 × 10 = 20 cents, and three nickels are 3 × 5 = 15 cents. Together that's 20 + 15 = 35 cents. Counting each coin type first makes adding easy!

Q4: Skye has $5.00 and buys a seashell necklace for $3.75. How much money does she have left?
  • $1.25
  • $4.00
  • $2.25
  • $5.75

💡 Subtract the cost of the necklace from Skye's total money to find out how much she has left.

🗼 Lighthouse KeeperLighthouse Fund Quest judge 80/100Bloom L3🪙 50 earned

Join Skye and save up to light the lighthouse in Harbor Cove!

Objective: Save for a goal · Standard: CEE Standard: Decision Making

📖 Skye needs to save coins to buy a new lighthouse bulb. She earns coins by finding treasures in Harbor Cove.

Q1: If Skye wants to buy a lighthouse bulb that costs $25 and she saves $5 each week, how many weeks will it take her?
  • 3 weeks
  • 4 weeks
  • 5 weeks
  • 6 weeks

💡 Skye needs $25 and saves $5 each week: $25 ÷ $5 = 5 weeks. Dividing the goal by the weekly amount tells you exactly how long a savings plan takes!

Q2: Skye has saved $40 for her lighthouse bulb. If the bulb costs $20, how much money will she have left?
  • $10
  • $20
  • $30
  • $60

💡 Skye saved $40 and the bulb costs $20: $40 − $20 = $20 left. Subtracting what you spend from what you saved shows what stays in your treasure chest!

Q3: If Skye wants to buy a big lighthouse bulb that costs $30 and she has 3 weeks to save, how much does she need to save each week?
  • $8
  • $9
  • $7
  • $10

💡 Skye needs $30 in 3 weeks: $30 ÷ 3 = $10 each week. Splitting a goal evenly across the weeks is how you build a savings plan!

Q4: Skye has saved $15 and needs a lighthouse bulb that costs $20. How much more does she need to save?
  • $4
  • $5
  • $6
  • $7

💡 Skye needs a total of $20, and since she has saved $15, she still needs to save $20 - $15 = $5 more.

PENNY knowledge base (12 entries)

Counting Coins (money-basics)

Counting coins means adding up the value of different types of coins to find out how much money you have.

Knowing how to count coins is important when you want to buy things at the harbor market or anywhere else. It helps you know if you have enough money and how much change you should get back.

Making Change (money-basics)

Making change is when you figure out the difference between the cost of something and the amount of money someone gives to pay for it.

When you're at the harbor market, making change helps both buyers and sellers. Buyers get back any extra money they don't need after buying something, and sellers make sure they get paid correctly.

Dockside Jobs (Earning)

Dockside jobs are work you can do near the water, like helping to clean boats or move supplies.

People earn money by doing different kinds of work around a harbor, which helps them pay for things they need.

Chores (Earning)

Chores are little jobs you do to help at home or in the harbor, like cleaning up or organizing stuff.

Doing chores can earn you money and teach you how to take care of things around a house or dock.

Lighthouse Fund (saving)

A Lighthouse Fund is like a special piggy bank where you save money for something big that you really want to buy one day.

Saving in a Lighthouse Fund helps you set a goal and work towards it by putting aside small amounts of money over time. This teaches patience and planning.

Goal Saving (saving)

Goal saving means setting up a special place to put your money little by little until you have enough to buy something important or fun!

By saving for a goal, you learn how to wait and save over time instead of spending all your money right away. This helps you get bigger things that are worth waiting for.

Needs (spending)

Needs are things you must have to live, like food and clothes.

Understanding needs helps you make smart choices at the market by focusing on what's really important for living well.

Wants (spending)

Wants are things that would be nice to have, but you don't need them to live, like toys or fancy snacks.

Knowing the difference between needs and wants helps you spend your money wisely at the market by choosing what truly matters to you and your family.

Oyster Bed (investing)

An oyster bed is like a garden in the ocean where lots of oysters grow and live together.

Just like how you plant seeds to grow vegetables, people can create oyster beds to help oysters grow. It takes time for oysters to get big, just like it takes time for your savings to grow!

Patient Money Growth (investing)

Patient money growth means saving and waiting a long time for your money to grow, kind of like how oysters take a long time to get big in their beds.

When you save your money patiently, it can grow into more over time, just like the oyster beds grow bigger with more oysters. It's important to be patient and not spend all your savings right away!

Entrepreneur (entrepreneurship)

An entrepreneur is someone who creates and runs their own business, like a bait-and-tackle stand.

Entrepreneurs take risks to make money by selling products or services they love. They work hard to get customers and keep the business running smoothly.

Revenue (entrepreneurship)

Revenue is the money that comes in when you sell things at your bait-and-tackle stand, like fishing rods or worms.

Revenue helps you know if your business is doing well. You use this money to buy more supplies and keep your stand open for customers.
