E) invented multi-digit addition strategies [4pts] show two invented (efficient) strategies that a student could use to solve 76+29. represent each strategy using both symbols and a model (e. g., base-10 blocks or an open number line). an 'invented strategy is not the standard us algorithm and is not a direct modeling or counting strategy if you were using base-10 blocks to solve the problem, you would be direct modeling, but here you're using the blocks to show how your invented strategy works, not to solve the problem, so it's okay to use those as your model. consider using color to show connections between the symbols and the model. 76+29 first strategy model symbols second strategy model symbols
