This document provides information about numbers from 1 to 1000 including: - Definitions of even, odd, composite, prime, and prime factors - A process for identifying prime numbers using a grid from 1 to 100 by eliminating numbers with composite factors - Demonstrations that prime numbers cannot be placed into rectangles while composite numbers can - Objectives of learning place values, writing numbers, comparing, and ordering numbers from 1 to 1000 - An example of expanded form of a numeral by writing it as thousands, hundreds, tens, and ones

1. Fun with numbers
Some Simple Tips

2. Definitions
• Even Numbers – Any number that
can be divided by 2
• Odd Numbers – Any number that
cannot be divided by 2
• Composite Number – An integer that
can be divided by at least one other
number (a factor) other than itself

3. Definitions
• Prime Number – An integer whose
only factors are 1 and itself.
• Factor – a number that can divide
another number without a remainder.
• Prime Factors – an expression of
numbers that divides another integer
without a remainder where all the
factors are prime.

4. What numbers are prime?
• Let’s look at a number grid from 1 to
100 and see how they were
discovered.
