The document describes a math lesson where students solved a word problem about a rope ladder hanging in a pool being filled with water. It discusses: - The problem of calculating how long it will take to fill the pool 1 foot per hour until the water reaches the top rung of the ladder. - The teacher had students work through it in steps and with partners using strategies like drawing pictures or making charts. - The teacher was surprised by the high quality of some groups' work and encouraged visual representations to solve it. - For next time, the teacher plans to add more closure and make the context more realistic.
