Topic Description
Introduction Learning how each graphical representation
depicts fractions as parts of a unit
1. Naming fractions Naming unit fractions and proper fractions,
given a graphical representation, comparing
fractions with like numerators and like
denominators
2. Making fractions Making representations given symbolic unit
fractions and proper fractions, comparing
fractions with like numerators and like
denominators
3. Reconstructing the unit Reconstructing the unit of a given fraction
4. Naming improper fractions Naming improper fractions and mixed
numbers, given a graphical representation
5. Making improper fractions Making representations given symbolic
SENSE MAKING AND PERCEPTUAL FLUENCY IN CONNECTION MAKING 2
improper fractions and mixed numbers
6. Concepts of equivalent fractions Learning about what makes fractions
equivalent
7. Procedures with equivalent
fractions
Finding several fractions equivalent to given
unit fractions and proper fractions
8. Fraction comparison Comparing fractions with unlike numerators
and denominators
9. Fraction addition Adding fractions with like denominators and
unlike denominators
10. Fraction subtraction Subtracting fractions with like denominators
and unlike denominators
