The Ratio &
Fraction Factory

A messy, yummy, squishy lesson.
You will build smoothies to find out the difference.

👩‍🏫 For grown-ups (30-second read)

The idea: a ratio compares two groups (2 : 3 — no total needed). A fraction compares one group to the whole (2/5 — the bottom number is the total). Children mix these up because both use the same two numbers.

The fix: the smoothie jar makes the invisible visible — add blueberries and the strawberry fraction shrinks even though no strawberry left. Then the "push the piles together" bridge shows where the denominator comes from: ratio parts added up.

Five stations: Explore → The Bridge → Sort it → Build it → Trophy. Let them tinker; the quizzes check understanding, not reading speed.

🧠 Things you now know

🦖A ratio compares two piles: 2 : 3 — "two to three".
🦊A fraction compares one pile to the whole: 2/5 — "two fifths".
🧱Add the ratio parts and you get the bottom number: 2 + 3 = 5.
🫐More blueberries ➜ the strawberry fraction gets smaller!
🍓Same flavour, different numbers: 2 : 2 and 3 : 3 are both half.
