Timber Times Lessons
Purpose: Students will practice computation of math facts, problem solving, and math apprlications while participating in a thematic unit on local history.
Standards Addressed: 3.5 Students demonstrate basic economic reasoning skills and an understanding of the economy of the local region.1. Describe the ways in which local producers have used and are using natural resources, human resources, and capital resources to produce goods and services in the past and the present. 2. Understand that some goods are made locally, some elsewhere in the United States, and some abroad. 3. Understand that individual economic choices involve trade-offs and the evaluation of benefits and costs.
Materials: Copies of the multiplication or time and money lessons for each student or pair of students.
Procedure: Students will read the Timber Times pages on this website, and will complete these lessons as part of a practical discussion of the effects of mathematical variables which determine profitability of mountain lumber interests.
Timber Times Multiplication
1.. A pack mule could carry five bags of cornmeal to the timber camps. If each bag held 50 pounds, how may pounds would the mule be carrying? _____________________________________________________________________________________
2. If a circular saw could cut four logs per hour into board lumber, how many logs could be cut in an eight hour day? _____________________________________________________________________________

7. Lumberjacks worked in teams with long two-man saws. If 18 teams were cutting trees at one time, how many lumberjacks would that be? _______________________________________________________________
8. The Brookings mill built a railroad along the rim of the mountain to haul logs to their sawmill. If the tracks were built at a rate of 60 feet per day, how many feet of track would be laid in seven work days? _____________________________________________________________________________________
9. Horses worked hard at the sawmills, hauling logs and pulling wagons loaded with lumber. If each horse ate 15 pounds of hay each day, how much hay per week would each horse need? _____________________________________________________________________________________
10. Orange crates were needed in the valley to pack fruit for the growing citrus industry. Each crate required twelve board feet of lumber. How many feet of lumber would it tale to build five orange crates? _____________________________________________________________________________________
How many feet of lumber to build 50 orange crates?_______________500 orange crates?______________
"Time and Money"
1. If workers at a sawmill start their day at 7:00 a.m. and end their shift at 4:00 p.m., how many hours have they worked?___________________________________________________________________________
2. Nellie Belle, the camp cook, started serving supper at 4:30 and finished up at 6:45. How long did she "scoop out the vittles?"_________________________________________________________________________
3. Pete the blacksmith worked all day repairing a broken part from the sawmill. He started at 8:30 and finally was done at 3:00. How long did it take to fix the part?____________________________________________________________________
4. Lorna May and Billy Bob went square dancing in Blue Jay. If they started dancing at 7:30 p.m. and finished at 11:15 p.m., how long were the couple kicking up their heels?____________________________________________________________________
5. It took and experienced teamster and his four-horse team to bring lumber down the mountain. If he left the sawmill at 10:45 a.m., what time could the teamster expect to be down at the box factory?____________________________________________________________________
6. The Mountain Turnpike Company operated a toll road and charged $2.00 for wagons, $0.50 for horses, $0.05 cents for sheep, and $0.25 for each pack animal. If Burt and Gus were driving a two-horse wagon, filled with 5 sheep how much would they be charged?____________________________________________________________________
7. What if Burt and Gus also had two pack mules tied to the back?____________________________________________________________________
