This lesson helps students develop an ability to compare and contrast as they explore two strategies to solve three-digit addition problems. This EL Math lesson can be used alone or alongside Three-Digit Addition Strategies Review.

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

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.
