Compare and Order Three
Order up to three fractions, including fractions greater than 1.
Warm-up, learn, try it together, practice, then a quick check. About 15 minutes.
What children learn in Level 58
- Let's order 3 fifths, 7 eighths, and 5 fourths. Start with benchmarks. 5 fourths is more than 1, so it's the greatest.
- 7 eighths is close to 1, and 3 fifths is just over one half. So 7 eighths comes next.
- When benchmarks don't settle it, use a common denominator. 2 thirds and 3 fourths are 8 twelfths and 9 twelfths.
- You can also match the tops. If two fractions have the same top, the smaller bottom means bigger pieces.
