Even Split

Pick a customer's order and assemble their fraction of a pie precisely by adding slices from your inventory. You can only use the slice sizes you're stocked with, so a half might have to be built from quarters or eighths. Fill an order exactly to serve it; skip one you can't complete and take a strike. The shift ends when every order is served or your strikes run out.

• Each order is a target fraction you must match exactly.
• Only the slice denominations in stock are available to use.
• Serve when your build equals the order; over- or under-filling won't pass.
• Skipping an order costs a strike, too many strikes end the shift.

• Daily (seeded): the same shift for everyone, in Easy, Medium, or Hard.
• Practice (random): fresh shifts at your chosen difficulty.

• Desktop: click an order to select it, then click slices from inventory to add them; Serve, Clear, or Skip.
• Phone & tablet: tap an order, tap slices to fill it, then tap Serve.

• Convert the order to the smallest available slice size so you can count pieces exactly.
• Spend scarce large slices on orders that truly need them, not ones you can build from small ones.
• If two orders compete for the same slices, serve the one you can't make any other way first.

Even Split builds genuine fraction sense by making you compose exact amounts from the slice sizes on hand, so equivalence, common denominators and adding fractions become something you do, not just memorize.

• Skills: equivalent fractions, adding fractions, common denominators, part-of-a-whole reasoning
• Best for: roughly grades 3–6 (ages 8–12)
• For parents & teachers: a quick, self-checking way to practise fraction fluency with instant feedback and no worksheets.

Building a customer's fraction out of the slice sizes you happen to stock — a half assembled from quarters or eighths — is arithmetic with dyadic rationals, fractions whose denominators are powers of two.

The original constraint is the inventory: you cannot make a third if you only hold halves and quarters, and no amount of cleverness will produce one.

That impossibility is the point. Repeated halving reaches a dense set of values and still misses most fractions entirely, which is a sharper way to meet common denominators than being told to find one — here the denominator you need either exists on your shelf or the order cannot be filled.
