Examples, solutions, videos, and songs to help Grade 2 students learn how to determine whether a group of objects (up to 20) has an odd or even number of members, e.g., by pairing objects or counting them by 2s; write an equation to express an even number as a sum of two equal addends.

Odd and Even Numbers
Determine whether a group of objects (up to 20) has an odd or even number of members by matching.
How do you know if a number is odd or even?
If objects can be grouped in 2’s the number would be even. If objects can’t be grouped in 2’s the number would be odd.
Odd & Even Numbers
Even numbers can be cut into two or more equal groups
Odd numbers cannot be cut into two or more equal groups
Even Numbers always end with 2, 4, 6, 8, 0
Odd Numbers always end with 1, 3, 5, 7, 9
We can skip count by 2 to get the even or odd numbers.
We can use the “buddy” rule or partner system.

A number is even if two people have the same amount.
Odd and Even Poem
Zero, two, four, six, eight
Being even is just great.
One, three, five, seven, nine
Being odd is just fine.
Even number song
This song reviews the concepts of even numbers (and helps teach the fact that all even numbers can be ‘split in half’)
Split em up,
Down the middle,
Split em up,
Say this rhyme…
Even numbers split,
Right down the middle,
Half and half,
Make even numbers
Say this rhyme,
If ANY number ends,
With one of those digits,
Then that number’s even,
Odd number song
This song teaches the odd digits, and shows that any number ending in an odd digit is also odd.
Can’t be beat,
Those 5 digits,
Are so sweet…
Hey odd numbers!
Go odd numbers!
The only odd digits,
All the time!
Show me a number,
Odd on the end
Then that number’s,
Odd my friend.
