Every plant costs seed money (🌱) and brings in money at harvest time (🧺). The profit is what is left - 💰 = 🧺 − 🌱.
Sometimes you are also told how many days the plant needs until harvest (📅). Then you keep going - 🌞 = 💰 ÷ 📅.
Above every task you see what is wanted - the biggest profit or the biggest profit per day. Check off the plant that wins.

For parents
What does this exercise practice?
Harvest profit practices two steps that build on each other. First the difference - profit is not what the harvest brings in, but what is left after the costs are taken off. Then the normalizing to a common unit - earning 20 in five days is less than earning 12 in two days. That makes it the first step toward working with rates, and because the division always comes out even, it is within reach in Grade 2.
Common pitfalls
The biggest printed number is never the answer - the most expensive harvest also costs the most seed money. And for profit per day, the plant with the biggest total profit almost never wins. Work out every row first and compare afterwards instead of guessing at a glance.
How to practice at home
While shopping, compare two packs - which one is cheaper per item? Or write down for a week how much pocket money adds up over how many days and work out how much that is per day.
