Students will get plenty of practice composing tens with ten frames to add to 20! Use this scaffolded EL Lesson alone or for more addition practice before teaching the Scavenger Hunt Addition 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.

Students will get to explore three-digit numbers through base-ten blocks and written form. Students will get plenty of practice identifying the place values of a number both individually and with the class.
