Bench 01
Fill Lab unit pours
Raise or lower liquid in a piggy pot, snap to unit fractions, switch denominator walls from halves through twelfths, and read the improper form as stacked whole jars plus a remainder pot.

Piggy Fraction Pots turns fraction rules into actions kids can see and fix themselves. In a soft pink-cream piggy-pots lab, learners raise liquid to unit snaps, lock equivalence pairs on a mirror bench, bridge common denominators for add and subtract, scale pots to multiply, and share fills across buddy pots to divide. Mixed numbers become whole jars you drag on and off a tower; comparison races leave the residual fill glowing before the chip sticks. Seeded Grade 3–5 paths, a 40-item story bank, and Worksheet Studio open fully populated on first launch—no accounts, no network—so parents and teachers get instant visual proof plus one-page PDFs from the share sheet.
Bench 02
Mirror Bench equivalence
Park two pots side by side, subdivide the walls, and lock matched pairs like 1/2 = 2/4 = 3/6 with an on-pot checklist before the path lets you advance.
Bench 03
Operations Bench bridges
Add or subtract on an animated common-denominator bridge, multiply by scaling pot size, divide by equal-share splits—each step undoable and narrated in plain kid language.
Bench 04
Compare Arena races
Race two pots, drop < = > chips, and highlight the residual fill so the size difference is visible before the symbol is accepted.
Bench 05
Whole-Jar Workshop
Convert mixed numbers and improper fractions by dragging full jars off a tower into unit pots and back, with live simplified output on every move.
Bench 06
Stories, Paths & Worksheet Studio
Solve scaffolded snack, ribbon, pizza, and allowance stories; stamp Grade 3–5 skill nodes; build a one-page practice PDF and share it for homework—answer keys stay offline.
