The document outlines assignments and lessons for math class. It lists that Set 67 odds problems are due the next day and Test #11 will be on Tuesday. It then provides sample math problems for a warmup, including finding the median of a data set, identifying if a statement about triangles is true or false, calculating sales tax, writing a number in scientific notation, and simplifying an expression. The main lesson introduces using ratio boxes to solve problems involving totals. It provides examples of using ratio boxes to set up and solve ratio and proportion problems.
