The Singing Teachers

Regent Honeyeaters are beautiful black and yellow birds from Australia that are famous for their lovely singing. But because there are so few of them left in the wild, young birds are forgetting how to sing! To save their song, scientists are bringing in older, wild birds to be "singing teachers" for the young ones. These "tutors" teach the young birds exactly which notes to sing so they can talk to each other and find mates. Learn more!
Wee Ones
If a young bird has an older bird to teach him the song every day, is it likely or unlikely that he will learn to sing?
Little Kids
Scientists found that the "singing school" works best when there are 5 young birds for every 1 teacher. If there is 1 teacher and 5 young birds, how many birds are in the classroom in total?
Big Kids
It takes about 3 months for a young bird to learn its full song. If a bird starts its singing lessons on April 1st, in what month will it finish its lessons?
The Sky's the Limit
There are only about 250 Regent Honeyeaters left in the wild. If scientists can help double the population, how many birds will there be?
