Open-Ended Questions in Math
What Is an Open-Ended Item? An open-ended math item asks students to solve a multi-step problem  and  explain   WHY   they chose each step .
PSSA   Each student has 4 open ended items on the PSSA 3 on the common form 1 on the matrix form
PSSA Each open-ended item has a maximum value of 5 points.  Therefore, open-ended items account for approximately 18% of the student’s PSSA score. Responses to open-ended items are graded using a rubric.
The PSSA Rubric To earn all 5 points, students need to show   each step   of their work, and explain   WHY   they chose   each  of their steps. They can earn at least 1 point by showing a correct step toward solving the problem.
Calculator Usage Calculators can be used for all open-ended items on the PSSA Students need to be familiar with using the specific calculator  before  the test!
The Directions For full credit, you must   do the following: Show OR describe each step of your work, even if you did it in your head (“mental math”) or used a calculator, Write an explanation stating the mathematical reason(s)  why   you chose each of your steps.
Tips for Solving from Teachers Make 2 columns Put “work” on the left Put “explanation” on the right work explanation
Solving Tips from Teachers Show and number   each step of the work Even/especially if the work was done in the student’s head or calculator.
Explanation Tips Encourage students to   EXPLAIN   their work - not   DESCRIBE   it Description: “ I multiplied $1.25 and 13 and got $16.25” Explanation “ I multiplied the price of gas per gallon and the number of gallons to get the price for the gas used.”
Explanation Tips from Teachers Make sure ALL steps are explained in words.  Encourage students  not  to use numbers in their explanations – this will stop them from describing their work.
Explanation Tips from Teachers Use “magic words”* in the explanation.  These are words that gear students to ‘explain’ their work rather than ‘describe’ it.  *  Article on “Magic Words” can be found in the math assessment handbook
What are the Magic Words? To find To get To see To figure out To show To determine Because  Since  Therefore…….
Explanation Tips from Teachers Encourage your students  NOT to use  the words “ to find THE ANSWER” The words  “the answer”  do not explain what the answer represents.
The Explanation 1)  I multiplied the price of gas and the number of gallons TO GET the total cost of gas. 2)  I added the cost of gas, food and tolls together TO FIND the total cost of the trip. 3)  I divided the total cost of the trip by the number of miles and I FOUND the cost per mile. 4)  SINCE I had many decimal places, I rounded to the hundredth BECAUSE I wanted money.
The Final Product Work 1)  $1.25 X 13 gal = $16.25 2)  $16.25 + $12.84 + $6.50 = $35.59 3) $35.59    221mi    $0.161041 4)  $0.16 per mile Explanation 1)  I multiplied the price of gas and the number of gallons TO GET the total cost of gas. 2)  I added the cost of gas, food and tolls together TO FIND the total cost of the trip. 3)  I divided the total cost of the trip by the number of miles and I FOUND the cost per mile. 4)  SINCE I had many decimal places, I rounded to the hundredth BECAUSE I wanted money .
