Mr. Schmidt’s Weekend – Bar Graph

Mr. William Schmidt is a respected teacher at the William McKinley Middle School. He needs to organize his schedule on the weekends in order to be prepared for class each Monday.

This weekend he has the following 5 main activities (with one word label) related to home life:

  • shopping/errands (shop)
  • cleaning/upkeep of home (upkeep)
  • sleeping/relaxing/alone time (sleep)
  • entertainment/family time (family)
  • cooking/eating (food)

This weekend he also has the following 5 main activities with labels related to his employment:

  • grade student assignments, he promised to return them Monday (grade)
  • prepare class presentation – power points, research ideas (plan)
  • create accompanying materials for students – worksheets, activities (make)
  • strategize class review for state achievement tests beginning in three weeks (think)
  • prepare for meeting with a student’s parents on Wednesday – student is struggling (prepare)

In order to organize his weekend to be the most productive, he decides to create a bar graph to visualize how he might organize his time best.

He considers the “weekend” to be from Saturday Morning 8:00 am to Sunday Night 8:00 pm; thus he has 36 hours in which to fit all 10 activities.

Mr. Schmidt allows himself 8 hours of sleep, and then allocates the rest as follows:

2, shop

3, upkeep

8, sleep

4, family

3, food

5, grade

4, plan

3, make
