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.

Introduce your students to multiplying multi-digit numbers with this lesson that gives them plenty of practice and has them play a game with a partner that makes the lesson fun!

Use this lesson to support students in understanding the symbols used to record numbers. This lesson can be used alongside Comparing Three-Digit Numbers or as a standalone, scaffolded EL support lesson.

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.

In this lesson, students use cubes to build arrays to represent factor pairs of numbers within 100. They use this understanding to identify multiples as well.

Students put their understanding of one and 10 more to work as they write word problems for classmates to solve. This lesson plan can be used alone or with Picture Addition.
