## Introduction

The Timeline of Mathematics at mathigon.org/timeline is a wonderful place to explore some of the greatest mathematicians and some of the biggest mathematical discoveries in history. In this scavenger hunt, students search the timeline for a variety of mathematicians and artifacts.

## Student Document

The document below has 40 items for students to find on the timeline. The items are listed in chronological order. Some options include:

- Invite students to work in small groups and see how many items them can find as a group.

- Use this as an ongoing assignment that students can work on over a certain period of time.

- Identify certain questions students should answer.

- Initially, only share a few pages with students. Share additional pages over the course of the school year.

- Make a copy of the document and edit the document.

Students will be viewing the timeline on a device, so it may be best for them to have a paper copy of the scavenger hunt.

## Teacher Notes and Answer Key

## Themes

Some names of well-known topics in mathematics aren't actually named for the first mathematicians to explore that idea. The timeline entries below appear in the scavenger hunt and provide examples of this idea.

## Continue the Activity

As a follow-up activity, encourage students to make up a scavenger hunt entry for a mathematician or artifact not included in this activity.
