What does it feel like to take 120 steps? In this lesson, students practice counting and completing word problems up to 120.

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.

Input some patterns to T-charts in this lesson. Use this lesson about input and output boxes as a precursor to finding patterns within word problems.
