# Clip 14/29: Standard 1: Making Sense and Perseverance Using Numeric Patterning Problem 1

## Overview

*Mathematically proficient students can explain correspondences between equations...They can understand the approaches of others to solving complex problems and identify correspondences between different approaches.*

Fran Dickinson leads a lesson on numerical patterning, in which learners are asked to investigate a numeric pattern and to generalize what they see happening as the pattern grows. In this clip, the learners individually review a copy of two students' work on the MARS "Buttons" task and then discuss what they know or a question that they have about the sample work. This clip is also indicative of standard standard 2 (reason abstractly and quantitatively).
