Drought--Ishmael plans to go fishing in his favorite pond. After one week, the water level drops 2 inches. After a second week, the water level dropped an additional 1\frac{1}{3} inches. Assume that 0 is the original water level.
Model the changes to the pond's water level after both weeks on the number line, then write an addition or subtraction equation.
