Unit 2 of our Illustrative Mathematics resource.
Students begin to advance their fraction knowledge with denominators 5, 10, 12 & 100, building on previous understanding of 2, 3, 4, 6, and 8. They learn about fractions with related denominators, using tools like number lines, fraction strips, and tape diagrams to grasp equivalence, and understand fractions in relation to benchmarks.
Students then recognize visual patterns and learn numerical methods for finding equivalent fractions, using factors and multiples of numerator and denominator. They also compare fractions by understanding their size relative to benchmark fractions.

Comparing Fractions by Making Common Denominators
Strategies for Comparing Fractions:
1) If denominators are the same, compare the numerators (# of pieces)
2) If numerators are the same, compare the denominators (size of the pieces)
3) Compare to benchmarks 1/2 or 1
5) Common Denominators (change both fractions to have common denominators)
