3. Reviewing Benchmarks What is a benchmark fraction?
Benchmark fractions are reference points. Think about a number line.
For example, we know that 5/8 is close to ½ because 4/8 = ½.
¼ ½ ¾

4. Using Benchmarks to Compare Fractions
Compare each pair of fractions using benchmarks. Copy the fractions and insert <, >, or =. Describe your strategy using complete sentences.
5/ /8
5/ /8
2/ /9
13/ /5
6/ /9
¾ /16

5. Using Benchmarks to Order Fractions
Use benchmarks to order the following fractions from least to greatest. Describe any strategies you used.
2/3, 7/9, 3/7
4/5, 4/12, 7/10, 5/6

6. Exit Ticket Describe benchmarks and how we use them.
Compare the following fractions: 4/ /5
Order the following fractions from least to greatest:
¾, 7/8, 5/6
