The Perfect Slice
Equivalence
Balance is Key
Fractions represent the same amount even if the numbers look different.
Simplifying Strategy:
Find the Greatest Common Factor (GCF) and divide both top and bottom!
\[ \frac{8}{12} \]
=
\[ \frac{2}{3} \]
"Same taste, smaller bites!"
The Foundation
Add & Subtract
1
Denominators
They MUST be the same. Like making sure all slices are the same size!
2
Numerators
Add or subtract only the top numbers. Keep the bottom the same.
3
Final Cut
Always check if you can simplify your final answer!
\[ \frac{1}{4} + \frac{1}{2} \rightarrow \frac{1}{4} + \frac{2}{4} = \frac{3}{4} \]
Topping It Off
Multiply & Divide
Multiply
Easy as pie! Multiply the numerators, then multiply the denominators.
\[ \frac{2}{3} \times \frac{4}{5} = \frac{8}{15} \]
Divide
Use the KCF Method:
Keep
Change
Flip
\[ \frac{1}{2} \div \frac{3}{4} \rightarrow \frac{1}{2} \times \frac{4}{3} = \frac{4}{6} = \frac{2}{3} \]

KEY RULE
Turn a Fraction into a Decimal...
\[ \frac{3}{4} \]
→
3 ÷ 4
→
0.75

The Baking Process
1
The Prep (10 mins)
Use the Dough Dynamics Slides to review core concepts. Ask students: "If I eat 2/4 of a pizza and you eat 4/8, who ate more?" to trigger prior knowledge of equivalence.
2
The Mix (15 mins)
Distribute the Slice Sorter Activity. Students match fractions and decimals to their simplest category. This reinforces "fraction sense" before tackling complex operations.
3
The Oven (20 mins)
Set up the Pantry Path Task Cards around the room. Distribute the Pantry Path Recording Sheet. Students work in pairs to solve word problems and operations involving the four basic fraction skills.
4
The Garnish (15 mins)
Individual assessment using the Supreme Slice Color Worksheet. This allows for a quiet check-for-understanding while students color their creations.
