Welcome to the Potion Shop!

You're the new apprentice brewer. Weird customers want weird potions — and every order is really a fraction. Shatter a crystal into equal pieces, grab the right amount, and brew it in the cauldron. Get it right and get paid!

Teacher's Guide: Fraction Brew

Fraction Brew turns fraction practice into a potion-shop crafting loop. Each customer's silly request is really a target fraction — students shatter a whole crystal into equal pieces, grab the right number of pieces, and pour them into the cauldron to measure the exact amount. Because students physically split the whole and count the pieces, the meaning of the numerator and denominator becomes concrete instead of abstract, and the game grows from unit fractions toward equivalence, common denominators, and operations across later tiers.

What Students Practice

  • Splitting a whole into equal parts (halves, thirds, fourths, sixths, eighths)
  • Reading a fraction a/b as "a pieces, each one b-th of the whole"
  • Matching a target amount by choosing the right number of equal pieces
  • Recognizing equivalent amounts (two fourths fill the same as one half)
  • Converting to a common unit — re-slicing a fixed wedge (like a 1/3 slice of a cheese wheel) into finer pieces to measure a different amount (like 1/4)
  • Finding a common denominator for unlike fractions and adding them, then rewriting the improper result as a mixed number (the "Incantation" that seals each advanced brew)
  • Self-checking their measure against a required amount before "brewing"

Standards Alignment

  • CCSS.MATH.3.NF.A.1 — Understand a fraction 1/b as one part when a whole is split into b equal parts, and a/b as a of those parts
  • CCSS.MATH.4.NF.A.1 — Explain why a fraction a/b is equivalent to (n×a)/(n×b)
  • CCSS.MATH.4.NF.B.3 — Build a fraction by joining unit fractions (a/b as a sum of 1/b's)
  • CCSS.MATH.5.NF.A.1 — Add fractions with unlike denominators by replacing them with equivalents that share a common denominator (the Incantation binds every essence to one shared common measure before adding)
  • CCSS.MATH.4.NF.B.3.C — Add fractions and rename a sum greater than one as a mixed number (drawing whole "runes" out of the improper fraction)

Classroom Tips

  • Use it as a math-center rotation — one order takes under a minute, so pairs can trade turns
  • Have students read the order aloud: "three fourths means split into 4, take 3" before they tap
  • Great warm-up: project it and solve one order together, thinking through the split out loud
  • Encourage the "wrong" path once — a fizzled potion is a safe, funny way to see a mistake
  • The Progress report (on-device) shows first-try accuracy per tier for a quick check-in
How long does a session take?

Each potion order runs about 30–60 seconds, so students can complete several in a short center rotation or a 5–10 minute warm-up. Progress (coins, recipes, and practice data) saves automatically on the device, so students can stop and resume anytime.

What grade range is this for?

It's designed for the 4th-to-5th grade bridge, rebuilding shaky fraction foundations before 5th grade operations. Tier 1 (unit fractions) suits confident 3rd graders too, while later tiers reach the 5th grade standard for adding and subtracting fractions with unlike denominators.

Does the game keep a wrong answer from being punishing?

Yes. A wrong measure simply "fizzles" with a silly message and lets the student empty the cauldron and try again immediately — there are no red X's, timers, or lost lives in the early tiers. Correct-on-the-first-try earns a small bonus, which nudges toward fluency without penalizing students who need to think it through.
