# Lesson 14

Exploración de estimación

### Lesson Purpose

The purpose of this lesson is for students to apply their understanding of measurement of fractional lengths to create an Estimation Exploration activity.

### Lesson Narrative

This lesson provides an opportunity to observe the ways in which students think about fractional measurements. After the warm-up, students create their own Estimation Exploration activity and then facilitate it with other students in the class. Students can find images to use for their Estimation Exploration from books or other provided sources, or use actual objects from around the classroom.

If students need additional support with the concepts in this lesson, refer back to Unit 6, Section A in the curriculum materials.
