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.

Use this lesson to introduce the tool of base-ten blocks to your students. This scaffolded EL support lesson can be used as a stand-alone activity, or prior to teaching Three-Digit Addition with Base-Ten Models.

Use this scaffolded EL lesson to teach students about money and the bills we use to pay for things. Use alongside Base Ten Money: Hundreds, Tens, and Ones or alone as an independent lesson.
