How to do this activity

Step 1. Take one of each of the three maps of Oregon and its counties, Average Annual Precipitation by County, Date Established of Oregon Counties, and Oregon Population by County. Step 2. At the bottom there is a guide, called a Legend, which tells you a number or date range. Look at the legend on each map, and see what the different colors represent. Step 3. Take a green marker, a yellow marker, and a red marker. Find the counties that fit between the ranges shown in the Legend, and color them to match. Step 4. Take one of the Questions sheets, and fill it out, referring back to the three county maps.
