Bubba Problem: Starting Friday, May 5, we will be playing stump the class. The students will read their Bubba problem out loud three times to the class. The class will try to solve the problem. For each incorrect answer given by their classmates, the reader will get one point. If they stump Mrs. Blick they get five points. There will be four grades for this assignment; the Written Question itself, Stump the Class, your class work, and a Participation Grade. First drafts are due Wednesday, May 3.
For the “Stump the Class” section, each student starts with a base score of 80 points. There are 27 students in the class, the reader will only need to stump 20 students to receive a 100. If the student can stump Mrs. Blick as well they receive an additional 5 points…the highest grade a student can earn is 105 points. See the Scoring Rubric for more info. Anyone who stumps all of the students in the room and Mrs. Blick will receive a special bonus!
Situation: Bubba has unlimited money and lots of friends. He can go anywhere and do anything he wants, provided it is in good taste and appropriate for school. Be creative, be tricky, but be clear! Students need to write a well worded math story problem, and the problem should have at least three steps before you get to the final answer.
Guidelines for creating your question:
1. Written Question: Must be in paragraph form and proof read for punctuation, spelling mistakes, capital letters, proper grammar, etc. See Question Rubric.
2. The Numbers – In the initial story question please keep the numbers small.
· Whole numbers cannot be bigger than four digits (i.e. 9999 or 99.99)
· No multiplication problem can be bigger than three places by four places, (i.e. 999 x 9999),
· No division problem can be bigger then a two digit divisor divided into a three digit dividend.
(i.e. 999 ÷ 99)
· Addition and Subtraction problems should not exceed four-place by four-place number (9999 + 9999) in the original question. As a second or third step in the equation; they should not exceed 9,999,999 + 9,999,999 (or 99,999.99 with a decimal). DO NOT try to multiply or divide numbers this big.
· Decimals should only go to the hundredths place.
· ANSWERS will obviously be bigger than the above numbers, and if they need to be combined with other numbers to get the final answer refer to the above guide lines.
3. Equation – Any equation involving whole numbers (9999) or decimals (99.99) can and should use any or all of the four functions (X, /, +, −) Students should use at least three different functions in their Bubba problem.
4. Division: Long division answers can have either remainders or fractions. Asking the class to figure out the answer where they need to conclude whether to use fraction or remainder is a good strategy. (i.e. “Bubba’s dog had a litter of 4 puppies, he is going to give his three best friends an equal amount of the litter. How many puppies does each friend get?” The students will need to decide if it should be a fraction or a remainder to get to the right answer? Think about it, can each person have 1 1/3 puppies?)
5. Fractions: When combining fractions, only use addition and subtraction (+, −), no multiplication or division of fractions. Fractions must have common denominators throughout the equation. Improper fractions as an answer are fine, but not as part of the question. Improper fractions must be expressed as a mixed fraction in the final answer. (i.e. 3/2 is not ok - 1 ½ should be the final answer). Remember to reduce fractions.
6. On the back of the written problem, or on a separate sheet of paper, the student needs to give the CORRECT ANSWER, showing ALL work.

Story Problem Grade / Notes:
The Answer is?
I have the correct answer to my own story problem / “Correct Math Wonder!” / ERRRrrrrr...
We have some lovely parting gifts for you.
If you can’t solve the problem, how is someone else going to do it?
