This resource teaches students various two-digit addition strategies and three-digit addition strategies including open number lines, base ten blocks, expanded form (composing and decomposing numbers), and more. The 2-digit addition strategies and 3-digit addition strategies activities, posters, and centers do not teach using the traditional algorithm! Common Core standards require students to be able to use different strategies to solve addition and subtraction problems, and this set focuses on ADDITION.
