“Hoy estimamos la cantidad de plástico reciclable que las escuelas de primaria pueden producir y la comparamos con la cantidad de plástico reciclable que Estados Unidos envía a otros países” // “Today we made estimates for the amount of recyclable plastic elementary schools might produce, and compared this with the amount of recyclable plastic that the United States ships abroad.”
“¿Cuáles son algunas de las estimaciones que hicieron o usaron hoy?” // “What are some of the different estimates you made or worked with today?” (The volume of recycling bins, the amount of plastic we put in the bins each day, the number of schools and the amount of recyclable plastics shipped.)
“¿En qué se parecen calcular usando estimaciones y calcular usando valores exactos? ¿En qué se diferencian?” // “How is calculating with estimates the same as using exact values? How is it different?” (I still need to know which operation to use. But the round numbers are easier to calculate.)
“Si supieran que hay 68,372 escuelas, en vez de 70,000, y que Estados Unidos envió 207,364 contenedores llenos de plástico a otros países, ¿cambiarían su respuesta a la pregunta de si las escuelas podrían llenar todos los contenedores? ¿Por qué?” // “If you knew that there were 68,372 schools, rather than 70,000, and the U.S. shipped 207,364 cargo containers of plastic, would that change your answer to the question of whether the schools could fill all of the containers? Why?” (No, I don't think I could find the value of the quotient but, it still should be close to 3.)
“Estimar no solo es importante para comprobar si las respuestas son razonables, sino también porque a veces no necesitamos un cálculo exacto para responder una pregunta” // “Estimation is important not only to check the reasonableness of answers, but also because we sometimes don't need an exact calculation to answer a question.”
