The purpose of this Number Talk is for students to demonstrate strategies and understandings they have for finding whole-number quotients of whole numbers with up to four-digit dividends and two-digit divisors. These understandings help students develop fluency and will be helpful later in this lesson when students will develop their own Number Talk activity.

• “¿A qué cosas tuvo que prestarle atención el autor de esta actividad cuando la diseñaba?” // “What did the writer of this activity have to pay attention to when they designed this activity?” (The values of the expressions need to be found mentally, so they can't be too complex.)
• “¿Dónde vemos estas cosas en la manera en la que cambian las expresiones durante la actividad?” // “Where do we see those things in how the expressions change during the Number Talk?” (The first expression helps to do the second one, and the first 3 help to do the last one.)
• “Imaginemos que esta ‘Conversación numérica’ tuviera una quinta expresión. ¿Por qué   sería una buena opción?” // “Imagine this Number Talk continued with a fifth expression. How does fit in with this Number Talk?” (It doubles the dividend and the divisor from the previous expression, which means the quotient is the same, 25.)
