The Jefferson Road duck is back in
the nature center busily waiting for ducklings. I was wondering
how many ducks have hatched over the past three years, if each duck
always lays 5 eggs that hatch. Assume that ducklings are only
hatched once a year. Start with one duck the first year.
How many ducks are there after 3 years?
Hint: Draw a picture.
For 4th and 5th grades: When the ducklings leave the nature
center, they walk about 3,000 feet to find water in the Erie
Canal. Is this greater than or less than a
mile?______________ Why?
