The document describes a scenario where a snail crawls up a pole each day but slides back down each night, and asks how many days it would take the snail to reach the top of poles of varying lengths, gaining 4 feet per day and losing 3 feet each night. It includes examples of poles that are 5 feet, 7 feet, and asks how many trips it would take for a pole of any length m feet.

1. Day 1
5-minutes

2. The Crawling Snail (Driscoll, 1999)
A snail crawled up a pole 5 feet in length.
The snail went up 4 feet during the daytime
and slid backwards 3 feet each night.
How many daytime trips would the snail take
to get to the top of the pole?
(Note: Once the snail gets to the top, it stays
there.)

3. Day 2
5 minutes

4. The Crawling Snail (Driscoll, 1999)
A snail crawled up a pole 7 feet in length.
The snail went up 4 feet during the daytime
and slid backwards 3 feet each night.
How many daytime trips would the snail take
to get to the top of the pole? What if the pole
was 25 feet in length?
(Note: Once the snail gets to the top, it stays
there.)

5. Day 3
5-minutes

6. The Crawling Snail (Driscoll, 1999)
A snail crawled up a pole. The snail went up
4 feet during the daytime and slid backwards
3 feet each night.
How many daytime trips would the snail take
to get to the top of the pole if the pole was m
feet tall?
(Note: Once the snail gets to the top, it stays
there.)
