Lesson 3
Gráficas de dibujos con escala
Lesson Purpose
The purpose of this lesson is for students to read and answer questions about scaled picture graphs.
Lesson Narrative
In previous lessons, students reviewed how to create and interpret single-unit scale picture graphs. In this lesson, students learn that a scaled picture graph is a picture graph where each picture represents an amount other than 1. They read, interpret, and answer questions about scaled picture graphs with a scale of 2 and 5, and generate questions that can be answered by these graphs.
Math Community
Tell students that, at the end of the lesson, they will be asked to identify specific actions from their “Doing Math” list (both teacher and student sections) they personally experienced.

Activity 1: Tantas respuestas
Learning Goals
Teacher Facing
- Interpret scaled picture graphs to generate questions (orally and in writing) about the data.
Student Facing
- Exploremos gráficas de dibujos con escala.

Teacher Reflection Questions
In this lesson, students make sense of scaling a picture graph by a number other than 1. How does this support the work that students will do with multiplication later in this unit?
