Each friend shows you one idea by how they act. Meet them all and see how the ideas fit together.

  1. Halver Partitioning — splitting a whole into equal parts (denominator construction)
  2. Pie Wholes and parts — mixed numbers, improper fractions, whole-as-pie anchor
  3. Equi Equivalent fractions — different forms, same value (×n/×n scaling)
  4. Stretch Common denominators — scaling to a common base for comparison + addition
  5. Dot The decimal point and fraction-decimal-percent equivalence
  6. Liner Number-line placement — every fraction has an exact spot between the whole numbers
  7. Gather Adding and subtracting fractions — you can only combine pieces that are the same size
  8. Times Multiplying fractions — a fraction OF a fraction, shown as the overlap of two strips
  9. Tenth Decimal place value — each column right of the point is ten times smaller
  10. Rank Comparing and ordering fractions using benchmarks and reasoning
