This document contains notes from a math class on solving problems. It includes examples of word problems about a snail climbing out of a well over multiple days, gaining height each day but losing some each night. It also shows a diagram tracking the snail's progress up the well over time. Students are assigned homework problems #1-8 on page 166 to practice solving similar types of multi-step word problems.
