UXO game to practice
'Is the number odd or even?' for 2nd grade

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.

With our UXO math game you will be practicing the topic "Is the number odd or even?" from 2nd grade / Comparing numbers / Odds and evens 20 to 100. The math in this game consists of 16 questions that ask you to choose whether these numbers from 20 to 100 are odd or even.

UXO is a click to clear game with multiple targets at different levels

Large thumbnail for math game UXO

UXO is a fun game to learn math where you attempt to knock over all the target objects while avoiding clicking / tapping on the bombs.

After each level, win an additional 50 points by correctly answering a math question from your selected topic. Wrong answers lose you 20 points but you can answer multiple times. Each level lasts 30 seconds: if you haven't cleared all the targets in that time, you lose 50 points. High scores can be added to the UXO leaderboards.


Notes

  • This is a fast-paced game of clicking or dragging over moving targets.
  • Also suitable for tablets and mobiles (it's actually easier than with a mouse)
  • Answer math questions correctly for a higher score
  • Hit all the targets in 30 seconds or you lose points.
