Fraction Blogging on blogging

On Tuesday you will have your final test on fractions. You may use your blogging on blogging post as a memory minder for the test. The more effort you put into your BOB the more you will be able to use for the test.

Blogging on blogging is a review of the unit. What went well for you, what did not. You are expected to reflect on your work habits during the unit. Did you do your work, all of it some of it etc.

This blogging on blogging is different. You can add images and other helpful hints to be a study guide for the test. Take advantage of this if you need to.

You need to include the following information in your BOB about the unproject.

1. Did you like the unproject.
2. Did the unproject make you work harder than you usually would?
3. What did you like best about the unproject?
4. What would you change about the next unproject?
5. Did the unproject make you learn more because you were doing a different type of project.

Thanks.
