Provide a list of sights around the state and have them look up and record the TRS numbers for each. If you can't remember how this was done at the workshop, look in the front of the DeLorme atlas of Washington. TRS is explained on the inside of the front cover. Practice using the overhead projector to demonstrate laying the grid over a map and aligning the grid numbers. Also practice finding the township and range numbers on the overhead.
Students take turns directing and being directed.
Distribute the grid transparencies. Have students practice laying the grids over the maps and lining them up correctly. Have each student write out the township number that corresponds to their home. Repeat, this time having students designate and record the appropriate quarter section. If possible have everyone record the TRS numbers for the areas where you will be doing your data collection.
