Use this lesson to introduce the tool of base-ten blocks to your students. This scaffolded EL support lesson can be used as a stand-alone activity, or prior to teaching Three-Digit Addition with Base-Ten Models.

Use this lesson to review three-digit addition strategies including base-ten drawings, number lines, and the standard algorithm.

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.
