Bella's Rainy Day Lesson

Bella always asked her Grandpa lots of curious questions.
One day, on the way to school, Bella asked Grandpa about money.
Bella wanted to have money of her own to buy lots of lollies.
So Grandpa taught Bella the 'Rainy Day' lesson. A clever money plan using three handmade piggy banks so Bella could save, spend and give.
It wasn't until her friend Ruby was having a birthday that Bella tried to apply the Rainy Day lesson. But could Bella learn the lesson?
