Types of numbers:  Numbers come in several varieties. Numbers can be odd, even, prime or composite. But what does this all mean?Read More
Even numbers – Let’s begin with even numbers. Even numbers are numbers that can be evenly divided into groups of two. Numbers such as 4 and 6 can be evenly divided into two groups. To determine if a number is an even number, we look at the numbers in the ones place and if they end in – 2, 4, 6, 8, 0, they are even.
Odd numbers – Meanwhile odd numbers are the opposite of even numbers. Odd numbers are numbers that cannot be divided evenly into groups of two. To determine if a number is an odd number, we look at the numbers in the ones place and if they end in – 1, 3, 5, 7 or 9, they are odd numbers.
Prime numbers – This is where it begins to get a little tricky. A prime number is a whole number greater than 1 that cannot be made by multiplying other whole numbers. In other words, its factors are one and the number itself. Further, a prime number can be divided without a remainder only by itself and by 1.
Composite numbers – A composite number is a positive integer (whole, not fractional number) that can be formed by multiplying two smaller positive integers.
Playing this game allows 4th graders to begin distinguishing between these numbers. Distinguishing between the numbers further reinforces core numeracy skills.Read Less
