This document contains a practice worksheet with math word problems involving rates and unit rates. Students are asked to write rates, unit rates, and compare rates for situations like boxes of kittens, biscuits from batches, revolutions in seconds, kilometers traveled in time periods, better purchase deals based on unit cost, and more. They are also asked to calculate rates like gallons of water leaking per hour from quarts per day and kilometers traveled per year by a glacier moving at meters per day. Finally, students are asked which grade read books at a higher rate per student and how many more one grade would need to read to have the same rate based on class sizes and numbers of books read.
