Help your student become a(n) Scanning with Intuitive Quantification Estimator

Children have experiences covering surfaces and talking about area (e.g., on the playground, "this is a really big area for our game" or ""we covered the whole table with no holes") can be helpful. In discussions, differentiate area from other quantities (e.g., "Her block building is taller than yours, but yours covers more of the rug!")
