I noticed one bird at the bird feeder on Monday. On
Tuesday there were four birds at the feeder. On Wednesday nine birds
visited the feeder. I counted sixteen birds at the feeder on Thursday.
If this pattern continues, how many birds came the feeder on Friday?
Show your work.
For 4th and 5th graders: How many birds came to the feeder on Sunday?
