An Even number is a number that can be divided exactly by 2:

2÷2= 1

4÷2=2

6÷2=3

8÷2=3

All Even numbers end in 0, 2, 4, 6, 8,

**Example:**

22 is even because it ends in 2

46 is even because it ends in 6

328 is even because it ends in 8

7520 is even because it ends in 0

844 is even because it ends in _______

548 is even because it ends in _______

**Odd numbers**

** Secret rules**

**Even + even**

Any two even numbers added together will give an even number

2 + 2 = 4 (even)

2(even)+4(even) = 6 (even)

8(even) + 20 (even) = ____(even)

6(even) + 14 (even) = ____(even)

___(even) + ___(even) = ____( _____)

___(even) + ___(even) = ____( _____)

**Odd + even**

Any two consecutive numbers added will give an odd number

1 + 4 = 5 (odd)

5(odd) + 6(even) = 11 (odd)

7(odd) + 4 (even) = ____ (odd)

3(odd) + 4(even) = ____ (odd)

7(odd) + 6 (even) = ____ (odd)

___(even) + ___(odd) = ____( _____)

___(even) + ___(odd) = ____( _____)

**Odd + odd**

Any two odd numbers added together will give an even number

ex: 3 + 3 = 6 (even)

5(odd) + 7(odd)= ___ (even)

5(odd) + 7(odd)= ___ (even)

___(odd) + 3(odd)= ___ (even)

___(odd) + ___(odd) = ____( _____)

___(odd) + ___(odd) = ____( _____)
