1. Fractions: Teaching with Understanding Part 4

2. We are learning to:
Represent fractions on a number line
Use reasoning strategies to order and compare fractions
Read and interpret the cluster of CCSS standards related to fractions
Success Criteria:
Clearly explain and provide examples for specific CCSS-M fraction standards

3. Compare Fractions by Reasoning about their Size
More of the same-size parts.
Same number of parts but different sizes.
More or less than one-half or one whole.
Distance from one-half or one whole (residual strategy–What’s missing?)
Write the strategy in your notebook and give an example of what this means.

4. Ordering Fractions
1/4, 1/2, 1/9, 1/5, 1/100
3/15, 3/9, 3/4, 3/5, 3/12
24/25, 7/18, 8/15, 7/8

5. Ordering Fractions Write each fraction on a post it note.
Write 0, ½, 1, and 1 ½ on a post it note and place them on the number as benchmark fractions.
Taking turns, each person:
Places one fraction on the number line
& explains their reasoning about the size of the fraction.

7. Reflect
Summarize how you used reasoning strategies to compare and order fractions based on their size.

8. Standard 3NF3d & 4NF2
On your slate, provide an example of comparing fractions as described in this standard.
Share with your partner.

9. Standard 3NF3d & 4NF2
On your Standards Interpretation Sheet rephrase this standard and provide an example. Share with your partner.

10. Translating the Standards to Classroom Practice
Discuss the progression of the standards we did today. Is the progression logical?
Discuss how the standards effect classroom practice. What will need to change?
