Equal Parts of a Shape
Cut a shape into parts with equal area. Each part is a unit fraction of the whole.
1Equal Area, Not Equal Shape
4 parts, 4 squares each
Equal parts must match in area, not in shape. Each part here covers four squares.
2Name One Part
1 of 4 equal parts = 1/4
One part out of four equal parts is one fourth of the whole shape.
3More Parts, Smaller Parts
More cuts make smaller pieces. Six parts each hold less than two parts do.
4Four Pieces Is Not Fourths
✗ four pieces
the shares are not fair
✓ four fourths
every share is the same
Fourths means four fair shares. Uneven pieces have no name yet, so cut again.
