SlateForge
Scrawl, a young crow, works fraction sums and equations in fast slanted ink, and one line always goes wrong: added the bottoms, forgot to flip, moved a number without changing its sign. Find the line, pick the fix, and tell Scrawl the rule. Then work your own: the margin only says "follows" or "doesn't follow yet". No answers given, nothing leaves your device.

#2f5d8a Distributed-narrative cast
Meet the cast
SlateForge's cast each carry one rule of fractions and equations, and you teach them to Scrawl. Scrawl writes fast and is still learning; Denna only adds pieces of the same size; Topsy flips the fraction you divide by; Evenhoof does the same to both sides; Crosswick changes the sign when a number crosses the equals sign.
Scrawl
(Hero and the novice you teach, a young crow with ink on its feathers) - writes fast, slanted working and makes the mistakes real learners make; learns each rule when you tell it
Denna
A heron who matches - only adds fractions once the bottoms are the same, then adds the tops and keeps the bottom
Topsy
A lemur who flips - to divide by a fraction, turns the second fraction over and multiplies
Evenhoof
A mountain goat on a balance beam - whatever happens to one side of an equation happens to the other
Crosswick
A fox at the equals sign - when a number crosses over, its sign changes: plus becomes minus
What's inside
Learning goal
Scrawl, a young crow, works fraction sums and equations in fast slanted ink, and one line always goes wrong: added the bottoms, forgot to flip, moved a number without changing its sign. Find the line, pick the fix, and tell Scrawl the rule. Then work your own: the margin only says "follows" or "doesn't follow yet". No answers given, nothing leaves your device.
