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.

Make multiplying by powers of ten more accessible to your students by focusing on patterns in the number of zeros!

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.

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.
