My reasons for this are:
- This unit encompasses the topics that students expect when beginning Geometry. The definitions at the beginning, the lines and angles that are not parts of actual shapes, etc. seem to really bother students. It's all the foundational knowledge of Geometry, but students don't see it as Geometry right away. They expect to see complete shapes, and expect to calculate perimeter, area, and volume of shapes because this is what they've experienced in the past.
- This unit relies on basic, foundational Algebra which serves to reinforce and review the key concepts of applying formulas and solving equations. This was the key to my decision. My students had multiple Algebra teachers the previous year, and their Algebra skills that I assessed the first days of school proved that their skills are weak.
Overall, I noticed that students struggled with this unit the same way the students did when I taught it last year. I need to find more hands-on activities for this unit. I feel that I really missed out on incorporating great learning experiences in this unit. I'll have to make finding activities for this unit one of my goals for this summer.
For this unit, my Interactive Notebook pages were not much different from the Measurement unit pages last year. For now, I am not planning to post about these pages.
