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.
4th grade / Decimals / Add decimals / Complements of number one
Decimal complements refer to the process of finding the complement of a decimal number with respect to a target number. In this topic, complements to 1, complement means the value that, when added to the given decimal number, will result in a sum of 1.
To find the decimal complement to 1, you can follow these steps:
For example, let's say we want to find the decimal complement to 1 of the number 0.75.
1 - 0.75 = 0.25
So, the decimal complement to 1 of 0.75 is 0.25.
Another example: Let's find the decimal complement to 1 of the number 0.412.
This is not as easy as the first example because the subtraction is harder:
1 - 0.412
Of course you can use a calculator to do this, but as mental arithmetic, the easiest way is to think of the digits after the point as a separate value, in this case 412. Because there are 3 digits, we subtract it from 1000, so we get 1000 - 412 = 588
Putting the decimal point back in, we can say:
1 - 0.412 = 0.588
So, the decimal complement to 1 of 0.412 is 0.588
With our Rock fall math game you will be practicing the topic "Complements of number one" from 4th grade / Decimals / Add decimals. The math in this game consists of 16 questions that ask you to identify the missing decimal complement to 1.
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.
