Game: ROCK FALL
Aim: Smash all the falling rocks
Method:
Click / tap on each falling rock. Answer the question in the box as quickly as you can.
There are only 4 questions in this game so it is quite short... if you can get those rocks!
Your final score is based on number of questions answered right / wrong, and the time taken.
2nd grade / Comparing numbers / Odds and evens 20 to 100 / Is the number odd or even?
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 Rock fall 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.
ROCK FALL is based on the road traffic warning sign for falling rocks - a sign that seems a bit less useful than somebody getting up there on that cliff and actually doing something about it... Anyway, the rocks are falling and it is your job to stop them hitting the road below, or at least stopping them hitting the road below too many times and breaking it. Smash the rocks by clicking or tapping on them (not so easy in real life of course) - they will turn into snowflakes and float gently down into nothing.
There are 4 rocks to stop and not much time to do it (if you want to get a good score and get on the leaderboard). This game is fun and fast and requires good reflexes and a good strategy. Plan to break the smaller rocks first if you want a good score because the rocks fall faster as the game progresses. It also helps to decide where on their path you plan to click / tap the rocks.
