Display the bar graphs from the Warm-up.
“Hoy interpretamos datos representados en una gráfica de barras. Usar una gráfica de barras es un poco diferente a usar una gráfica de dibujos para responder preguntas” // “Today we interpreted data represented in a bar graph. Using a bar graph is a little different than using a picture graph to answer questions.”
“Compara la manera en que usaron una gráfica de barras para responder preguntas y la manera en que usaron las gráficas de dibujos. ¿En qué son diferentes?” // “How are the ways you used a bar graph to answer questions different from how you used picture graphs?” (The bar graphs have a scale that helps you see how many are in each group without having to count each one. You really had to read the bar graphs to make sure you were counting the right thing because there weren't pictures that matched each group.)
“¿En qué se parecen?” // “How are they the same?” (They both show a number in each group. You can count each picture in a picture graph and you can count each part of the bar in a bar graph.)
