## Instructional Time: 45 minutes on Day 2Each student will receive a worksheet with one math word problem that would have been something the railroad builders faced. Topics will include money spent, number of workers, hours of labor, and distance of railroad track. The students will attempt to solve the problem on their own, using what they know about addition, subtraction, multiplication and division. They will include the following: -An equation that represents the math that the problem requires -At least 3 sentences explaining why they used that equation -A solution to the problem -A picture or diagram that shows their reasoning During the last 15 minutes, students will form groups with other students who had the same word problem (3-4 students per group). Each student will present his or her solution to the group for feedback. After every student has presented, the students may make additions to their worksheets before turning them in for evaluation.
