Extra Credit

At a rural cabin, you get water from a well using only a 4-gallon bucket and a 9-gallon bucket. In a single trip from the well to the cabin, what whole number gallon amounts of water could you bring back to the cabin?

There are no markings on the pails.  And, you can’t do any estimating or add any markings!

The easy ones are

4- fill up the 4-gallon bucket

9- fill up the 9-gallon bucket

13- fill up both buckets

Extra Hint- all gallon amounts 1-13 are possible.  For the credit, explain how to come up with the gallon amounts 1, 2, 3, 5, 6, 7, 8, 10, 11 and 12.

Extra Extra Hint- 5- Fill up the 9 gallon bucket.  Pour 4 gallons into the 4 gallon bucket leaving 5 gallons in the 9 gallon bucket.
Give an explanation for how to come up with each gallon amount.

The correct answer will include all possible gallon amounts and the correct process for obtaining each gallon amount.

Write out the answers including the correct processes and email me the answers with procedures.

About Me


This is my 17th year teaching (6 years elementary and 11 years high school).  My wife, Alison, is also a teacher in NMUSD.  She teaches 5th grade at Adams Elementary School.  We have 2 children, Benjamin and Juliet.  My goal is to help each and every student that enters my classroom complete the high school Algebra requirement and satisfy the  applied skills (+ technology proficiency) requirement.  Helping my students mature and grow in character is a goal as well.  I also teach/sharpen computer skills that will improve a student's marketability in the workforce and efficiency as a college student.
