# 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.

### Learning Goals

Teacher Facing

• Interpret scaled picture graphs to generate questions (orally and in writing) about the data.

### 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?
