Target: Grade 6–8 Reteach
No-Panic Vocabulary Decoder (Say These Plainly)
Improper Fraction: Numerator is bigger than or equal to denominator (e.g., \(\frac{7}{4}\)). It just means "more than one whole cut into equal slices."
Reciprocal ("Flipped Fraction"): Turn the fraction upside down. The reciprocal of \(\frac{2}{3}\) is \(\frac{3}{2}\). A number times its reciprocal always equals 1.
Unit Rate: A rate comparing an amount to exactly one unit (e.g., miles per 1 hour, dollars per 1 pound). Found by dividing top by bottom!
Inverse Operation ("Opposites"): The math action that undoes another action. Addition undoes subtraction; multiplication undoes division.
PERIOD 1: Fraction Mechanics (Mixed Numbers & KCF Division)
45–50 Minutes
Skill 1: Mixed Number to Improper Fraction (The "M-A-D" Method) 15 Min
1. Multiply (M):
Multiply the denominator by the whole number. (Gives total slice pieces in the wholes).
2. Add (A):
Add the existing numerator to that product. (Adds the leftover slices).
3. Denominator (D):
The denominator stays exactly the same! (Slice size did not change).
Script for \(2\frac{3}{4}\): "Look at \(2\frac{3}{4}\). The denominator is 4. Multiply \(4 \times 2 = 8\). Add the top: \(8 + 3 = 11\). The denominator stays 4, giving \(\frac{11}{4}\). Two whole pizzas cut in fourths is 8 slices, plus 3 extra slices is 11 slices!"
Skill 2: Dividing Fractions via Keep-Change-Flip (KCF) 25 Min
Why does KCF work? Dividing by a fraction is the same as asking: "How many of these pieces fit inside the total?" Multiplying by its flipped reciprocal finds the exact same answer faster.
KEEP Leave 1st fraction untouched
CHANGE Change \(\div\) to \(\times\)
FLIP Flip 2nd fraction (reciprocal)
Script for \(\frac{3}{5} \div \frac{2}{3}\): "We keep \(\frac{3}{5}\). We change division to multiplication. We flip \(\frac{2}{3}\) to its reciprocal \(\frac{3}{2}\). Now multiply straight across: top times top \((3 \times 3 = 9)\), bottom times bottom \((5 \times 2 = 10)\). Result: \(\frac{9}{10}\)."

PERIOD 2: Unit Rates with Fractions & One-Step Equations
45–50 Minutes
Skill 3: Unit Rates Involving Fractions (Complex Fractions) 20 Min
A fraction inside a fraction \(\frac{A}{B} / \frac{C}{D}\) is simply a division problem wearing a disguise!
Word Problem Script: "Marcus hikes \(\frac{3}{4}\) of a mile in \(\frac{1}{2}\) hour. What is his speed in miles per hour?"
1. Set up the ratio: \(\frac{\text{miles}}{\text{hour}} = \frac{3/4}{1/2}\)
2. Rewrite as division: \(\frac{3}{4} \div \frac{1}{2}\)
3. Apply KCF: \(\frac{3}{4} \times \frac{2}{1} = \frac{6}{4}\)
4. Simplify: \(\frac{6}{4} = 1\frac{2}{4} = 1\frac{1}{2}\) miles per hour!
Skill 4: One-Step Equations (Opposite Operations & Reciprocals) 20 Min
Goal: Isolate the variable (get \(x\) alone). Whatever we do to one side of the equal sign, we must do to the other side to keep balance.
Case A: Variable is Divided \(\frac{x}{4} = 6\)
The variable is divided by 4. The opposite of dividing by 4 is multiplying by 4 .
\(\frac{x}{4} \times 4 = 6 \times 4 \implies x = 24\)
Case B: Fraction Coefficient \(\frac{2}{3}x = 8\)
Multiply both sides by the reciprocal \(\frac{3}{2}\) to turn the coefficient into 1.
\(\frac{3}{2} \times \frac{2}{3}x = 8 \times \frac{3}{2} = \frac{24}{2} = 12\)
Red-Alert Mistakes & What to Say to Fix Them
Flipping the 1st fraction: "Only the second fraction gets flipped! The first fraction stays seated: Keep it, Change sign, Flip the next!"
Cross-multiplying too soon: "Cross-multiplication is only for proportions with an equal sign in the middle (\(\frac{a}{b} = \frac{c}{d}\)). For division, write out KCF first!"
Dividing by whole numbers: "Always put a 1 under any whole number before flipping (e.g., \(4\) becomes \(\frac{4}{1}\), and its flip is \(\frac{1}{4}\))."
Daily Routine Anchor
Start each class with 2 warm-up problems on the board. Emphasize that algebra is just a balance scale: whatever you multiply or divide on the left side, you copy on the right side.

Rule #1: Fractions are not monsters—they are just pieces of wholes! Slide 1 of 6
Skill 1 • Period 1
The "M-A-D" Method
Mixed \(\rightarrow\) Improper
M
Multiply
Multiply the bottom denominator by the whole number.
\(3 \times 2 = 6\)
A
Add
Add the top numerator to your product.
\(6 + 1 = 7\)
D
Denominator
Keep the exact same denominator on the bottom!
\(2\frac{1}{3} = \frac{7}{3}\)
Example: \(2\frac{1}{3}\) \(\rightarrow\) \((3 \times 2) + 1 = 7\) over \(3\) \(\rightarrow\) \(\frac{7}{3}\)
Skill 2 • Period 1
Dividing Fractions: K-C-F
Multiplying by Reciprocal
KEEP
First fraction stays identical
\(\frac{3}{4}\)
CHANGE
Change \(\div\) into \(\times\)
\(\times\)
FLIP
Flip second fraction upside-down
\(\frac{5}{2}\)
Problem: \(\frac{3}{4} \div \frac{2}{5}\) → KCF: \(\frac{3}{4} \times \frac{5}{2} = \frac{15}{8}\) → \(1\frac{7}{8}\)
Never divide fractions directly—always turn it into a multiplication problem!
Skill 3 • Period 2
Fractional Unit Rates
Per 1 Single Unit
Real-World Scenario
"A chef uses \(\frac{3}{4}\) cup of flour to make \(\frac{1}{3}\) of a cake. How much flour per 1 whole cake?"
Unit Rate = \(\frac{\text{Flour}}{\text{Cake}} = \frac{3/4}{1/3}\)
1 Write as division: \(\frac{3}{4} \div \frac{1}{3}\)
2 Apply KCF: \(\frac{3}{4} \times \frac{3}{1}\)
3 Multiply: \(\frac{9}{4} = 2\frac{1}{4}\) cups per cake
Key Takeaway: A complex fraction is simply a fraction division problem written top-over-bottom!
Skill 4 • Period 2
One-Step Equations with Opposites
Keep the Balance!
Case 1: Variable is Divided
\(\frac{x}{5} = 4\)
Opposite of \(\div 5\) is multiply by 5 on both sides!

Cracking Mixed Number Rate Problems
Step-by-Step Blueprint • "Per Means Fraction Bar" • Scripted Think-Aloud
Target: Word Problem Mastery
The Golden Rule: "PER" is the Fraction Bar!
Students freeze because they do not know which number goes on top. Teach them this exact visual chant:
"Miles PER Hour" →
Miles (Numerator) Hours (Denominator)
"The word before 'per' goes on top. The word after 'per' goes on bottom."
The 5-Step Problem-Solving Blueprint
Step 1: Words Write the target rate as words with a fraction bar (\(\frac{\text{miles}}{\text{hours}}\)).
Step 2: M-A-D Convert all mixed numbers into improper fractions. Never divide mixed numbers!
Step 3: Setup Place improper fractions into the ratio, then rewrite as a horizontal division (\(\div\)).
Step 4: K-C-F Keep 1st fraction, change to multiply, flip 2nd fraction (reciprocal), then multiply.
Step 5: Units Simplify to a mixed number or integer, and attach the exact unit label!
Classroom Script Anchor Problem: "Brandon's Run"
5 1/4 miles in 1 1/2 hours
Teacher Says: "Let’s read the problem: 'Brandon ran \(5\frac{1}{4}\) miles in \(1\frac{1}{2}\) hours. Determine Brandon's speed in miles per hour.' Notice that question asks for miles per hour . That is our mission clue!"
Step 1: "Write the word ratio on your board: \(\frac{\text{miles}}{\text{hours}}\). Miles is on top, hours is on bottom."
Step 2: "Look at \(5\frac{1}{4}\). Use MAD: \(4 \times 5 = 20\), plus \(1 = 21\). That is \(\frac{21}{4}\). Now look at \(1\frac{1}{2}\): \(2 \times 1 = 2\), plus \(1 = 3\). That is \(\frac{3}{2}\)."
Step 3: "Write the division: \(\frac{21}{4} \div \frac{3}{2}\)."
Step 4: "Now use K-C-F! Keep \(\frac{21}{4}\). Change \(\div\) to \(\times\). Flip \(\frac{3}{2}\) to \(\frac{2}{3}\). Let's multiply: \(\frac{21 \times 2}{4 \times 3} = \frac{42}{12}\)."
Step 5: "Divide 42 by 12: 12 goes into 42 three times with 6 left over, so \(3\frac{6}{12} = 3\frac{1}{2}\). Never stop at the number—add the unit label: \(3\frac{1}{2}\) miles per hour !"
