Standard A.5(B) • Stations 01–08 Solutions & Step-by-Step Modeling
Stations 01–08 Breakdown:
5 Flips (01, 04, 05, 07, 08) • 3 Freezes (02, 03, 06)
Station 01 FLIP (Divide by -5)
-5x ≤ 35
→ Divide both sides by -5: reverse symbol
Final Solution: x ≥ -7
Closed circle at -7, shade right -7
Station 02 FREEZE (Divide by +8)
8m > -48
→ Divide both sides by +8 (positive divisor keeps symbol)
Final Solution: m > -6
Open circle at -6, shade right -6
Station 03 FREEZE (Divide by +3)
3y + 11 ≤ 26
→ Subtract 11: 3y ≤ 15 → Divide by +3
Final Solution: y ≤ 5
Closed circle at 5, shade left 5
Station 04 FLIP (Divide by -2)
-2p - 9 > 5
→ Add 9: -2p > 14 → Divide by -2: flip > to <
Final Solution: p < -7
Open circle at -7, shade left -7
Station 05 FLIP (Multiply by -4)
k / -4 < 6
→ Multiply both sides by -4: flip < to >
Final Solution: k > -24
Open circle at -24, shade right -24
Station 06 FREEZE (Multiply by +3)
(w / 3) - 7 ≥ -2

Final Solution: n ≤ -3
Closed circle at -3, shade left -3
Station 08 FLIP (Divide by -5)
14 - 5t > 39
→ Subtract 14: -5t > 25 → Divide by -5: flip > to <
Final Solution: t < -5
Open circle at -5, shade left -5

Final Solution: c ≥ 7
Closed circle at 7, shade right 7
TEACHER FACILITATION & MISCONCEPTION ALERTS
Trap 1: Negative Constants
In Station 09 (\(6r < -12\)), students often flip because \(-12\) is negative. Emphasize: the divisor (\(+6\)) determines the flip, not the numerator.
Trap 2: Variable on Right
In Stations 07 & 12, students struggle to graph when \(a\) is on the right side. Teach students to symmetrically rewrite: \(-3 < a\) becomes \(a > -3\).
Trap 3: Subtraction vs. Division
In Station 10 (\(b + 18 \ge 7\)), students sometimes flip when subtracting 18. Remind: addition and subtraction never flip inequality symbols!
