Cindy says she found a shortcut for doing multiplication problems. When she multiplies 3x24, she says,"3x4 is 12ones, or 1ten and 2ones. Then, thereās just 2tens left In 24, so add it up, and you get 3tens and 2ones." Do you think Cindys shortcut works? Explain your thinking in words, and justify your response using a model or partial products.
