# Lesson 2: Patterns in Numbers

## Getting Started

### Questions to Explore

• What patterns can we identify in numbers?
• How do patterns help us in math?

### Skills

• Count within 1000; skip-count by 5s, 10s, and 100s
• Model with mathematics
• Represent whole numbers as lengths from 0 on a number line diagram with equally spaced points corresponding to the numbers 0, 1, 2, etc.

### Materials

• colored pencils or markers
• fine point dry-erase marker (kit)
• Interactive Notebook
• laminated number grids (kit)
• laminated number line (kit)
• scissors
• snack foods* (Activity 4 - optional)
• stapler
• whiteboard (kit)

* - denotes an optional material that may or may not be needed

### Introduction

Materials: fine point dry-erase marker (kit), whiteboard (kit)
This lesson reviews and extends counting by 2s, 5s, and 10s using both a number line and a number grid and focusing on the patterns these numbers create. Much of the work in this lesson will be built upon in coming lessons.

Ask your child to restate the definition of a pattern. Give her the whiteboard and a dry-erase marker, and ask her to create a color pattern. Also ask if she thinks that there are patterns in numbers and, if so, what some examples of these might be.
