o “Lonnie’s has more boys than any other group and all groups have the same number of
kids (or 18 kids),” or
o “They are the only group with more boys than girls,” or
o “They have the greatest number of boys and the fewest number of girls of any group,” or
o “10/18 are boys,” or “There are 10 chances out of 18.”

(2 points possible)
1 point for correct answer of 4,000 (with or without square feet),
AND

1 point for correct and complete procedure for finding area shown and/or explained.
● Give credit for the following explanations or equivalent:
o Area is found by multiplying the length by the width. The length is 80 feet and the
width is 50 feet. Therefore, the area is 4,000 (square feet), or
o A = 80 x 50 = 4,000 (square feet), or
o Correct procedure (l x w = A) to find area is used, but answer is incorrect due to a
calculation or copy error.

Note: Do not give credit for copying the formula l x w = A only.
Part 2:

(2 points possible)
1 point for correct answer of 260 (with or without feet),
AND

1 point for correct and complete procedure for finding perimeter shown and/or explained.
● Give credit for the following explanations or equivalent:
o Perimeter is found by multiplying the length and the width times two, then adding these
two numbers. Two times 80 is 160. Two times 50 is 100; therefore 160 added to 100 is
260 feet, or
o P = 2l + 2w = 2(80) + 2(50) = 160 + 100 = 260 (feet), or
o Diagram correctly labeled on all four sides (l = 80, w = 50), or
o Correct procedure (l + l + w + w = P) to find perimeter is used, but answer is incorrect
due to a calculation or copy error.


Note: Do not give credit for copying the formula l + l + w + w = P or 2l + 2w = P only.

MATHEMATICS OPEN-RESPONSE ITEM E

AR4M02N107Y130-130R

E. Jake used the 100’s chart above to solve a mystery number puzzle with the following clues:

● It is a two-digit number greater than 23, but less than 50.
● It is an even number.
● Two, four, and twelve are some of its factors.
● The sum of its digits is a two-digit number.
What is the mystery number?

DESCRIPTION
Correct answer of 48. Work and/or explanation is correct and contains:
• Elimination Clue by Clue Method:
Numbers, charts, lists, calculations and/or words clearly show or explain the procedure of
elimination. Clues 1 and 2 may be combined. At a minimum, the numbers remaining after

performing Clue 3 (24, 36 and 48) or Clue 4 if reversed (28, 38, 46 and 48) are listed.
OR
• “48 is the number that fits the Clues” Method:
Four clues are addressed or repeated. Work is shown for Clue 3 AND Clue 4.
Elimination may be partial or missing.
o Example: “It’s 48 because it’s between 24 and 49, it’s even, 2, 4 and 12 are factors because
48/2 = 24 and 48/12 = 4, and the sum of its digits is a 2-digit number since 4 + 8 = 12.

Correct answer of 48. Work and/or explanation is incomplete, but is beyond repeating clues.
• Elimination Method is shown or explained (for at least Clues 1 and 2), but elimination using
other clues is missing or incomplete in some respect. Three to four clues are addressed or
repeated.
o Example: Verbal description of elimination clue by clue, but the numbers remaining after
performing Clue 3 (or Clue 4 if reversed) are not listed.
o Example: 23-50 are listed, with all numbers crossed out except 48 without differentiation
between clues or explanation.
o Example: Chart lists numbers between 23 and 50 and eliminates odd numbers. Clue 3 and/or
Clue 4 are addressed or repeated.
OR
• “48 is the number that fits the Clues.” Method is incomplete, but some work is shown for
either Clue 3 OR Clue 4. Three to four clues are addressed or repeated. Elimination of other

numbers is partial or missing:
o Example: “It’s 48 because it’s between 24 and 49, it’s even, 48/2 = 24 and 48/12 = 4.”

2

• Answer of 24, 36 and 48. Response explains process of elimination by going through Clues 1,
2 and 3, with 24, 36 and 48 remaining. (Does not proceed far enough – Clue 4 is not
addressed.)
OR
• Answer of 28, 38, 46 and 48. Response explains process of elimination by going through
Clues 1, 2 and 4, with 28, 38, 46 and 48 remaining. (Does not proceed far enough – Clue 3 is
not addressed.)
OR
• Correct answer of 48. Three to four clues are addressed or repeated with no supporting work
for Clue 3 and no supporting work for Clue 4.
o Example: “It’s 48 because it’s between 24 and 49, it’s even, 2, 4, and 12 are factors and the
sum of its digits is a 2-digit number.”
OR
• Correct answer of 48. One to two clues are addressed or repeated, with or without work or
elimination shown and/or explained.
o Example: “It’s 48 because it’s between 24 and 49 and it’s even.”

1

• Answer of 48. No clues are addressed, no work is shown or explained, or work contains
vague, but not incorrect, procedure.
OR
• Answer is an even number between 23 and 50 (≠ 48). At least one clue is addressed.
o Example: “It’s 44 because it’s greater than 23 and less than 50.”
o Example: “It’s 24 because 2, 4, and 12 are its factors.”


0

No understanding shown.
o Example: 48 with obvious use of incorrect procedure.
o Example: An even number (≠ 48) between 23-50 with no clues addressed: “It’s 44.”
o Example: Any odd number.

Solution and Scoring

Answer: The mystery number is 48.
Explanations may be:
● Numerical –
o Clue 1: All numbers from 24 to 49 (or 23 to 50) are listed.
o Clue 2: All odd numbers are eliminated: 24, 26, 28, 30, 32, 34, 36, 38, 40, 42, 44, 46, 48
remain.
o Clue 3: All numbers that do not have two, four and twelve as factors are eliminated: 24, 36
and 48 remain.
o Clue 4: All numbers whose digit sum is not a two-digit number are eliminated: only 48

remains.

Note: Some students perform Clue 4 before Clue 3 (after Clues 1 and 2).
♦ Example: 28, 38, 46 and 48 remain since the digit sum is a 2-digit number. Then, the only
number remaining with factors of 2, 4 and 12 is 48.
OR

● A chart – The numbers are listed and eliminated clue by clue. The clues are differentiated in
some way.

OR

● Verbal – The response contains a correct and complete verbal explanation of the procedure
using elimination clue by clue, with at least 24, 36, and 48 mentioned (or 28, 38, 46, and 48 if
Clue 4 is performed before Clue 3).
o Example: “First, I omitted all of the numbers that were not greater than 23 or less than 50.
Then I omitted all of the odd numbers, since it said the number was even. Then I crossed
out all of the numbers that 2, 4, and 12 did not go into, leaving 24, 36 and 48. Then I saw
which of these numbers had a 2-digit sum and it was 48.”
