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 / Fractions / Compare fractions / Which fraction is bigger?
Knowing which fraction is bigger or smaller is not always obvious. If we compare fractions that have the same number on the bottom (the denominator) like β , β and β , then the bigger the number on the top (the numerator) the bigger the fraction is.
If we compare β to β , we can see that these two fractions have the same denominator of 5. The numerators are 4 and 2. So we can say that β is the bigger of these two fractions. This makes sense because if I have β of a pie, that is more of the pie than if I have only got β of the pie.
There is another type of fraction that we need to talk about, unit fractions.
A unit fraction is the name for a fraction where the number on the top is a 1.
So Β½ is a unit fraction and so are β and β but β is not because it's numerator is not 1, it is 2.
Comparing unit fractions to find the biggest is not as easy as our first example. If we think about the two most common unit fractions, ΒΌ and Β½, we will see why. Which is bigger, ΒΌ of a cake or Β½ a cake? The answer is that Β½ a cake is a bigger share of the cake than ΒΌ of a cake even though the denominator of Β½, which is 2, is smaller than the denominator of ΒΌ, which is 4.
In the same way, if we compare ΒΌ with β to decide which is bigger, we will find that a ΒΌ share of that nice cake is a bigger share of the cake than a β share. So ΒΌ is a bigger fraction than β .
So now we can compare some fractions with the same denominator, and we can compare some unit fractions, and we can decide which is the biggest and which is the smallest.
With our Rock fall math game you will be practicing the topic "Which fraction is bigger?" from 2nd grade / Fractions / Compare fractions. The math in this game consists of 16 questions that ask you to for each pair of fractions, choose which one would be the bigger share of a whole.
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.
