Scaffolding estimation understanding (",)

Love this very visual way to scaffold students' understanding of estimation and build number sense. Students use the containers with 10 and 100 as comparisons to estimate the "mystery number" in the middle container.

Estimating the number of cubes it takes to fill each container, then fill and count to check.
