What children learn in Level 60
- Every fraction is built from unit fractions: fractions with 1 on top. 3 eighths is 1 eighth, plus 1 eighth, plus 1 eighth.
- Whole numbers can be built from unit fractions too. One whole is 4 fourths, so 2 wholes are 8 fourths.
- At the bakery, each pie is cut into 6 slices. 3 pies make 18 slices: 18 sixths!
