Never a numbers person? Try pies.
SLICE turns math into pie puzzles you can see. Watch a short lesson, then play it: fill pies, cut them into equal slices, spin a spinner or read a pie chart. Two minutes a day is enough.
5 LEARNING PATHS, 161 PUZZLES
• Foundations: fractions, decimals, percent, angles and clock time
• Fraction Operations: add unlike slices, take a slice of a slice
• Ratio & Proportion: share in a ratio, scale a recipe up
• Percent & Money: discounts, tips and "what percent?"
• Probability & Stats: spinner chances and pie charts
SEE IT, THEN PLAY IT
Every world starts with a short animated lesson. Pies split, merge and change color until the idea clicks. Then you try it yourself.
ONE PIE, MANY NAMES
1/2 = 0.5 = 50% = 180° = 30 min. Same size, same color, every time. A pie key shows how degrees, minutes and percent fit one whole pie.
MISTAKES THAT TEACH
Every puzzle says what to do in plain words. Make two mistakes and a "Why?" card shows what went wrong. Each win shows how the pieces add up.
