LET’S BREAK IT DOWN!
Make pairs of chopsticks.
You have 6 chopsticks. You can put all 6 chopsticks into groups of 2. 6 is an even number. An even number of objects can be paired in groups of 2 with nothing left over. You can count by 2s to see even numbers: 2, 4, 6, 8. When you count by 2s you add a pair each time.

Make pairs of shoes.
You have 6 shoes. The shoes are in pairs. 6 is an even number. If you take 1 shoe away there are now 5 shoes. 1 shoe has no pair. 5 is an odd number. Odd numbers are numbers where one object cannot be paired. 1, 3, 5, 7, and 9 are all odd numbers.

Make pairs of bracelets.
You made 20 friendship bracelets. You want to give the bracelets away in pairs. Count the bracelets as you make pairs: 2, 4, 6, 8, 10, 12, 14, 16, 18, 20. 20 is even because 20 objects can be put into pairs.

Find the pattern.
Here are some even numbers: 2, 4, 6, 8, 10, 12, 14, 16, 18, 20. Do you see a pattern? The digits in the ones place repeat: 2, 4, 6, 8, 0. If the digit in the ones place is even, then the whole number is even. In 34, 4 is even so 34 is even. In 35, 5 is odd, so 35 is odd.

Write an equation to show even numbers.
Even numbers can be shown in two equal groups. 10 can be put into two groups of 5. 5 + 5 = 10. 16 can be put into two groups of 8. 8 + 8 = 16.
