Poor tiny Birdie has no house. But Birdie does have friends. Spike, Queenie, Goldie, and Fidget want to help Birdie find a house of his own. Birdie needs a house that isn't too tall and isn't too thin, that isn't too short and isn't too fat, and that isn't too wide and isn't too narrow. Will they find a house for Birdie before the rain falls and the wind blows? A sweet and simple story about helping out a friend explains the math concept of capacity -- what will fit in a container of a particular shape and size.

A House For Birdie is about a small bird named Birdie who does not have a home. Birdie is always out in the rain during storms because she doesn't have a house that is the right size for her, so she asks her friends to help her find a home. All of her friends are different sizes. While out finding a house for Birdie the other birds all find houses that are the right fit for them. When it rains again, Birdie is still out in the rain so Birdie's friends build her a house that is just right for her.

Birdie needs a house. With the help of his friends, they find him a house that is perfect just before the rain and the wind come.
