The big ideaFriends can save together for something shared. Agree on a fair plan first.
How it works
Ria and Jo wanted a striped tent that cost 20 pretend coins, a lot for one child.
Alone, Ria needed 7 weeks and Jo needed 10. Together they save 5 coins a week, so it took 4 weeks.
They agreed on a fair plan first, and wrote down who puts in what.
Two jars filling at once get there sooner.The jar grows 5 coins each Saturday.
Example 1: Together each week
Ria saves 3 coins and Jo saves 2.
3 + 2 = 5
So the jar gets 5 coins every week.
Example 2: Count to 20
Each Saturday adds 5 coins.
5 + 5 = 10
10 + 5 = 15
15 + 5 = 20
The jar is full after 4 Saturdays.
Example 3: Another pair of friends
Mina saves 4 coins and Lee saves 3.
4 + 3 = 7 coins a week together.
In 2 weeks: 7 + 7 = 14 coins.
Example 4: Why together is sooner
Ria alone needs 7 weeks.
Together they need 4 weeks.
7 − 4 = 3
So saving together is 3 weeks sooner than Ria alone.
Alone and together.
Words to know
together
Both friends putting coins in the same jar.
fair plan
Agreed first, so both friends know who puts in what.
shared
Belongs to both friends, like the tent.
Watch out
Add the two amounts for the weekly total: 3 and 2 make 5, not 6.
Agree on a fair plan before you start, and write down who puts in what.
Hiding the jar, or forgetting who put in what, is unfair to a friend.
A friend can help you keep going, as Ria did when Jo nearly spent the coins.
