# What's my number? A math challenge

## A MATH CHALLENGE FOR YOUNG STUDENTS

**WHAT'S MY NUMBER? **

## I want to join one of the projects now!

Give your students the chance to develop numerical sense and to appreciate mathematics from a multicultural perspective!

Allows students to create a "math puzzle" in which the reader needs to figure out which numbers to use (based on clues given by the author) and then answer to the math problem!

**PROJECT DESCRIPTION**

**Project runs twice and begins October 20! - March 1st.**

`I`**n this project the students are asked to do two things:**

**Create**a set of clues (written and illustrated) that challenge other students to use math to determine a specific number.**Solve**other math challenges posted by participants in this project

Here an example of a math challenge sent by a student in Argentina to Delmar students in USA many years ago.*From Pablo and Luciano:*

- The number of the States in the United States of America
- + plus the strings of a Stradivarius.
- _ minus the number of people in a soccer field
- x times the age of the football player Maradonna when he won the World Cup in 1986.

**About the clues:**

**No numbers.**Use descriptions of the number to lead others to determine the number.- The clue has to mention something that anyone can guess even if he lives in another country
- If you can, illustrate your clue with a drawing

**Be sure to solve your own challenge before you send it to others!**
