Lesson 1

Patrones que crecen

Lesson Purpose

The purpose of this lesson is for students to analyze, describe, and extend visual patterns in which one or more shapes grow by a rule.

Lesson Narrative

In grade 3, students identified patterns in numbers and used mathematical operations to explain them. In this lesson and the next few, students continue the work of analyzing and describing shape and number patterns, looking for features of patterns that are not apparent in the rule.

The patterns in this lesson consist of shapes that use an increasing number of objects in each step. Students describe not only the rule of the pattern (that is, how the number of objects is changing), but also any features of the patterns that are not explicit in the rule. They also extend patterns and make predictions by looking for and making use of structure (MP7), rather than by drawing or writing out each step along the way.

Required Preparation

Activity 2:

  • Consider preparing a set of pattern blocks for building the first two or three steps of the giraffe pattern. The set should include 6 hexagons, 6 triangles, 3 trapezoids, and 24 squares.

Teacher Reflection Questions

Reflect on whose thinking was heard today. Reflect on whose thinking was not heard but could have enriched the conversations. What prompts or structures might better enable the latter to share their voices and reasoning?
