What's My Number? - Math Challenges
What's My Number?
Project Timeline: Ongoing
Project Age Group: elementary through secondary school
In this project, students are asked to do two things:
- Create a set of clues that challenge other students to use math to determine a specific number.
- Solve other math challenges posted by participants in this project.
Let's see if you can make math challenges that:
- contain no numbers. Use descriptions of the number to lead others to determine the number.
- contain a clue that mentions something about the area where you live and/or your interests.
You can also send any other math challenges that you would like to write.
Be sure to solve your own challenge before you send it to others!
Here is a sample of a math challenge sent by a student in
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.
How to Join:
- Teachers are asked to show their interest to the project itself, filling out the Application form
- All students must answer the 4 Kidlink questions in order to get their login and password to enter their math challenges and solve the challenges of others in the project. Students can answer the 4 Kidlink questions here: http://www.kidlink.org/registration/
How to Participate:
- Teachers have to create their Introduction school page by clicking "Create Page" at the bottom from the page of the current year.
- Students have to post their math challenges and art to illustrate their challenge by clicking on "Create Page" at the bottom of the webpage for their class. In order to post a math challenge students must have a login and password.
- Students can solve the math challenges of other students by clicking on "Add Comments" and posting their solution. We ask all students who solve math challenges to describe for us how they solved them.
- Teachers have to activate students pages and comments (They will receive an alert email with a link)
- develop number sense and explore other numeration systems
- identify the multiple uses of numbers in the real world
- develop common understandings of mathematical ideas and definitions
- acquire confidence in using mathematics meaningfully
- appreciate mathematics from a multicultural perspective
- select an appropriate computational method
- formulate questions and develop problem-solving strategies
- solve word problems with a variety of structures
- estimate and judge the reasonableness of answers
- collect, organize, display and interpret data
- demonstrate and apply the concept of measurement using various types of units
- work cooperatively
- justify their thinking
- recognize and describe patterns
- use calculators in appropriate computational situations
- use technology and the Internet as a tool for problem solving and information gathering
- value the role of math in our culture and society
