Misconceptions & Remediation Scripts

High-frequency student errors with scripted educator verbal corrections and pacing routines.

Indiana Checkpoint 1

Teacher Notes

Standards 7.NS.1 & 7.NS.2: "Subtracting a negative always stays negative" Sign Errors

Student Error: Calculating \(7 - (-15) = -8\) or \(-12 - 8 = -4\) by combining signs indiscriminately.

Teacher Script: "Remember: subtraction is adding the opposite. Replace \(a - b\) with \(a + (-b)\). For \(7 - (-15)\), flipping the operation and the sign gives \(7 + (+15) = 22\). On our number line, distance between coordinates is always positive: \(|p - q|\)."

Standard 7.NS.3: "Distributing a negative only changes the first term" Algebraic Distribution

Student Error: Writing \(-4(2a + 5) = -8a + 5\) or \(-5(3y - 4) = -15y - 20\).

Teacher Script: "The coefficient outside must multiply every term inside the parentheses. Draw arrows to both terms. \((-4) \times (2a) = -8a\) and \((-4) \times (+5) = -20\). Multiplying a negative by a negative inside turns positive: \((-5) \times (-4) = +20\)."

Standard 7.NS.4: "Putting negatives in numerator and denominator keeps it negative" Fraction Equivalence

Student Error: Writing \(-\dfrac{2}{3} = \dfrac{-2}{-3}\) thinking both positions require a negative sign.

Teacher Script: "A negative divided by a negative equals a positive! So \(\frac{-2}{-3} = +\frac{2}{3}\). A single negative fraction has exactly ONE negative sign: either in front \(-\frac{2}{3}\), on top \(\frac{-2}{3}\), or on the bottom \(\frac{2}{-3}\)."

Standards 7.NS.5 & 7.NS.6: Incomplete Factorization & Distributing Radicals Exponents & Radicals

Student Error: Stating \(8 \times 9\) is the prime factorization of 72, or believing \(\sqrt{64 + 36} = \sqrt{64} + \sqrt{36}\).

Teacher Script: "8 and 9 are composite numbers, not primes. Decompose until all leaves are prime: \(2^3 \times 3^2\). For square roots, you must evaluate the sum inside first: \(\sqrt{64 + 36} = \sqrt{100} = 10\). Notice that \(\sqrt{64} + \sqrt{36} = 8 + 6 = 14 \neq 10\)."

Page 2 of 2

Standard 7.NS.4 • Equivalent Fractions & Signed Division Rule: \(-\frac{p}{q} = \frac{-p}{q} = \frac{p}{-q}\)

Tier 1: Sign Placement

How to Solve: Negative fraction has EXACTLY ONE negative sign (front, numerator, OR denominator). Two negatives equal positive!

\(-\frac{3}{7} = \frac{-3}{7} = \frac{3}{-7}\)
\(\frac{-6}{-11} = +\frac{6}{11}\)

Tier 2: Decimal Quotients

How to Solve: Count negative signs: opposite signs give negative quotient. For reciprocals, flip fraction but KEEP the negative sign.

\(-14.4 \div 1.2 = -12\)
Recip of \(-\frac{4}{7} \to -\frac{7}{4}\)

Tier 3: Fraction Division

How to Solve: Keep-Change-Flip: \(\frac{a}{b} \div \frac{c}{d} = \frac{a}{b} \times \frac{d}{c}\). Convert mixed numbers to improper fractions first!

\(-\frac{4}{5} \div \frac{8}{15} = -\frac{4}{5} \times \frac{15}{8}\)
\(= -\frac{3}{2} = -1\frac{1}{2}\)

Standard 7.NS.5 • Prime Factorization & Exponents Rule: Decompose to prime leaves

Tier 1: Prime vs. Comp

How to Solve: Primes have exactly 2 factors (1 & itself). 2 is the ONLY even prime. 0 and 1 are neither.

Primes: \(2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31\dots\)

Tier 2: Exponential Form

How to Solve: Use factor tree. Group repeated prime factors using exponent powers: \(a \times a \times a = a^3\).

\(72 = 8 \times 9 \to \text{not prime!}\)
\(72 = 2^3 \times 3^2\)

Tier 3: Equations & GCF

How to Solve: Divide out known factors to find variable exponent. Perfect squares have ALL EVEN exponents.

\(360 = 2^3 \times 3^2 \times 5^1\)
\(a+b+c = 3+2+1 = 6\)

Standard 7.NS.6 • Squares, Roots & Inverse Operations Rule: \((\sqrt{x})^2 = x\) • \(\sqrt{x^2} = x\)

Tier 1: Roots ≤ 144

How to Solve: \(\sqrt{n}\) asks: "What number multiplied by itself equals \(n\)?" Memorize perfect squares 1 to 144.

\(\sqrt{64} = 8\), \(\sqrt{121} = 11\)
\((\sqrt{36})^2 = 36\)

Tier 2: Roots 144–400

How to Solve: Memorize benchmarks: \(13^2=169, 14^2=196, 15^2=225, 16^2=256, 17^2=289, 18^2=324, 19^2=361, 20^2=400\).

\(x^2 = 144 \implies x = 12\)
\(\sqrt{y} = 15 \implies y = 225\)

Tier 3: Radicals & Equations

How to Solve:
• Neg outside: \(-\sqrt{a}\) means \(-(\sqrt{a})\). (Note: \(\sqrt{-a}\) is NOT a real number).
• Solve \(\sqrt{x}\): Isolate radical, then square both sides.
• Operations: Simplify inside the radical first!

\(2\sqrt{x} = 26 \implies \sqrt{x} = 13 \implies x = 169\)
\(-\sqrt{81} = -9\) • \(\sqrt{100 - 36} = \sqrt{64} = 8\)
