A small fee every year eats more than it looks, because taken coins stop growing.
Omar and Tess each planted 100 pretend coins and both gardens grew the same way. Tess's garden had a keeper who charged a fee.
A fee is a price for a service, like tending the garden. Each year the keeper took one coin for every fifty inside.
Two coins sounds tiny, but the keeper came back every year, and coins taken stop growing too.
These are some of the questions on the sets. The printable sheets have more and an answer key.
6 coins. 300 holds six fifties.
108 coins. 110 − 2 = 108.
45 coins. 256 − 211 = 45.
How much, how often, and for what. These three questions show what a fee is really worth.
With a grown-up, find a fee they pay for a service, like a membership. How much is it, how often, and what does it get them?
Find a fee a grown-up pays for a service, like a membership, and ask the three questions together: how much, how often, and what does it get them? The gardens here are made up, so keep it about the idea.
