Reply To: Lesson 2 – How To Measure Quantities – Discussion

1. I would give them a box to wrap for a gift.

2. We would measure surface area.

3. We would measure in square inches.

4. How big of a surface area of wrapping paper do I need to wrap the box and why? Is it helpful to estimate before I wrap? Do we actually do this already but you didn’t realize it before?

I wonder how the students will connect the idea of when we wrap that we estimate using the visual of the object for easier wrapping? Too much paper and the extra makes it a difficult task. Too little and you have a hint to the gift. This is one thing I would like students to realize. They use estimation and math often they just don’t recognize it.
