Standards: 7.NS.A.1a, 7.NS.A.1b, 7.NS.A.1c, 7.NS.A.1d · Level: Grade 7
Question 1 Adding Integers (2 points)
(a) 17 − 8 = 9, so −17 + 8 = −9.
(b) 5 + 11 = 16, so −5 + (−11) = −16.
−9 and −16
Scoring: 1 point per part.
Question 2 Subtracting Integers (2 points)
(a) 6 + (−15) = −9.
(b) −8 + 13 = 5.
−9 and 5
Scoring: 1 point per part.
Question 3 Number Line Model (3 points)
(a) −5 + 8 = 3.
(b) 3 − 8 = 3 + (−8) = −5.
(c) |3 − (−5)| = 8.
−5 + 8 = 3; −5; 8
Scoring: 1 point per part.
Question 4 Night and Day Temperatures (3 points)
(a) 9 − (−12) = 21.
(b) 9 − 15 = −6.
(c) |−6 − (−12)| = 6.
21°F; −6°F; 6 degrees
Scoring: 1 point per part.
Question 5 Decimals and Fractions (3 points)
(a) 6.5 − 2.8 = 3.7.
(b) −1.4 + (−3.9) = −5.3.
(c) −812 + 312 = −512.
3.7; −5.3; −512
Scoring: 1 point per part.
Question 6 Gull and Fish (3 points)
(a) Gull: 32, fish: −18. Distance: |32 − (−18)| = 50 m.
(b) −18 + 27 = 9.
(c) 32 − 9 = 23 m.
50 m; 9; 23 m
Scoring: 1 point per part.
Question 7 Debt and Deposit (2 points)
(a) A deposit equal to the opposite of −62.50: −62.50 + 62.50 = 0, so $62.50.
(b) −31 + 31 = 0, and 0 + (−4) = −4.
$62.50; −4
Scoring: 1 point per part.
Question 8 Find the Unknown (2 points)
(a) ? = 4 − (−9) = 13.
(b) 5 + (−?) = 12, so −? = 7 and ? = −7. Check: 5 − (−7) = 12.
13 and −7
Scoring: 1 point per part.
