Students sketch base-ten blocks in this lesson that builds both number sense and fluency adding to 20!

Let’s start building numbers! Just as building skyscrapers is a visual representation of mathematics, students will use the visual representation of base-ten blocks to add—or build—onto a two-digit number.

Your young scientists will have tons of fun visiting measurement stations and using tools to measure various objects. They'll even be able to create posters at the end of the activity.
