Reflection: Rigor Calculating Flooring Costs - Section 3: Student Practice


Looking back on this lesson, there are two elements that I would like to change next time I teach it! 

1. I wouldn't provide students with a budget. Due to the budget, students gravitated toward using flooring that cost an estimate of $1.00 to save money. This limited the students to easier calculations and decreased the level of rigor in today's lesson.

2. I would have asked students to find the exact cost of flooring for their homes. Originally, I had avoided having students multiply a three digit number (130 square feet area) by decimal number ($1.39 per square foot) to calculate the cost of flooring per room as this is not a 4th grade standard. However, I have since decided that students could just use a calculator to find the product! 

3. I could have also shown students how to create a Google Spreadsheet to record and calculate their costs.
