Students sketch base-ten blocks in this lesson that builds both number sense and fluency adding to 20!

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 will practice listening comprehension skills after reading “The Paper Bag Princess” together as a class. Afterward, students will role-play, make inferences, and use summarization to strengthen literacy skills.
