| Click on link to view the first lesson plan in my "fear-free" fraction unit. |
| Also note that this lesson plan could be extended to include the incorporation |
| of computer technology objectives listed above. |
| How would you define what makes up a fraction? |
| How would you order a set of fractions from least to greatest? |
| Compare a fraction and its equivalency how are they similar? How are they different? |
| If you had the following set of fractions 1/2, 2/4, 4/8, 8/16...what would you predict the |
| next fraction to be? |
| What is the value of fractions in math? |
Last lesson plan of unit. Last lesson plan. Adaptations for this lesson include powerpoint presentations that the children have developed during this unit plan. Children also will present their graphs created with the spreadsheet programs available.
