Name:
Goal:
To learn different mathematical vocabulary and use it to communicate
clues.
To learn how to use number concepts such as multiples, primes, factors,
sum, product, quotient
T o learn the divisibility rules.
To make a creative display for outside the classroom
Project:
You are going to choose two different numbers and create clues that
lead to the Mystery Number.
Your clues can’t be too obvious that makes it easy, but also need to
lead to only one number.
Numbers must be displayed in some kind of creative style so that we can
display them in the hallway.
Both mystery numbers must have answers that are hidden.
Mystery Number 1
Must be two digits
You must use only four clues
Clues must lead to only one
number
Must use mathematical vocabulary in all clues
Must use different types of clues using different kinds of
mathematics

Mystery Number 2
Must be greater than 99
Must use only five clues
Clues must lead to only one
number
Must use mathematical vocabulary in all clues
Must use different types of clues using different kinds of
mathematics

An example would be something like:
I have a two digit number
It is a multiple of 4
It is a square number
One of its factors is 9
Don't underestimate how hard this project is for some students. The key is that there can only be one answer and many students have difficulty obtaining only one answer and have to continuously rework their clues. I get students to check other students work. It definitely helps everyone get that general understanding of some of these number concepts that students forget every year. They get practice with multiples and factors and prime numbers as well as many other aspects of mathematics.
Let me know what you think.
