Practice subtracting fractions with like and unlike denominators.
Find a common denominator, rewrite each fraction, then subtract the numerators. For 5/6 − 1/4: use twelfths → 10/12 − 3/12 = 7/12.
Cubles kits are geometry in your hands: nets, faces, edges and vertices that fold and click into a poseable 3D character. No scissors, no glue, about 15 minutes.
