4 IN A ROW game to practice
'Is the number odd or even?' for 2nd grade
2nd grade / Comparing numbers / Odds and evens 20 to 100 / Is the number odd or even?
Decide if the number is odd or even for numbers from 20 to 100
If we count up the numbers from 1 to 10 we get a list like this:
1, 2, 3, 4, 5, 6, 7, 8, 9, 10..
There are 2 types of numbers in that list. Half of them are "even" numbers and half of them are "odd" numbers.
We can understand the difference between odd and even numbers by thinking about pairs of things. Some things come in pairs, like socks, shoes or gloves. You need 2 of them (a pair) because you have two hands and two feet. Some numbers can make a pair, and some cannot. 2 is a pair (having 2 shoes is having a pair of shoes). Another number that makes a pair is 4, because 2 twos add together to make 4 without anything left over. The same for 6 and 8 and 10. These are the even numbers.
Other numbers can't make a pair without something left over. 3 is like that. If you try to make a pair from 3, you find that you have a pair of ones but there is one left over. This type of number is called odd. The other odd numbers in our list are 1, 5, 7 and 9.
This topic asks you to identify which numbers are odd and which are even. The numbers you will see are between 20 and 100, but it doesn't matter how big the numbers are because you only actually need to look at the last digit of the number, and decide if it is odd or even. Any number whose last digit is even is an even number. Any number whose last digit is odd is an odd number.
Here are some example questions from this topic:
Question : Is 52 odd or even? Answer : even
The answer is even because the last digit of 52 is 2 and you know that 2 is an even number.
Another example question is:
Question : Is 47 odd or even? Answer : odd
The answer is odd because the last digit of 47 is 7, and you know that 7 is an odd number.
