Reflection: Flexibility Decomposing to Compare Daily Salaries - Section 2: Guided Practice


During the guided practice portion of this lesson, I realized that I had too many presentation slides! For the daily salary comparisons, there were 4 slides, monthly salaries: 4 slides, and annual salaries: 4 slides. I found myself skipping slides here and there in order for students to be exposed to tasks that varied in complexity. If I had the opportunity to teach this lesson over again, I might only show 2-3 slides per section (daily, monthly, and annual salaries). Either way, I would rather be over-prepared than underprepared any day!
