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.

Build familiarity with numbers from 1 to 120 with this fun game. This lesson can be used alone or with the lesson plan Then Came One.

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.

Use this lesson to familiarize students with the place value of each digit within a three-digit number, along with practicing the written form of three-digit numbers. Use prior to teaching Place Value Hop or as a stand alone activity.
