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.

Meet your mentor
Every Spark & Anvil app has a friendly mentor character that demonstrates, asks, and patiently scaffolds learning.

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
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
