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.
5th grade / Multiply + Divide / Order of operations / Order of operations: missing divisor
This topic reinforces the mutual relationship between multiplication and division - we say they are inverse operations. Each question starts with a number. That number is multiplied by a second number then divided by a third number (we call this a 2 step operation). In this topic the answer is given, but the third number (the divisor) is missing and needs to be calculated.
To calculate the divisor you need to multiply the initial number by the second number, then divide that value by the answer of the 2 step equation. What we are doing in effect is taking the missing number with its divide sign to the other side of the equation which changes the divide sign to multiply. We then move the answer with its multiply sign to the left side of the equation where it becomes divide.
So, in the first question from the lesson we have an equation of the form:
4 x 8 ÷ ▢ = 16
We can calculate the missing value ▢ by moving the ÷ ▢ to the other side of the equation which converts it to x ▢. So now we know that:
4 x 8 = ▢ x 16
We can now move the x 16 across from the right to the other side where it becomes ÷ 16. No we have:32 ÷ 16 = ▢
So the solution is that the value of the missing divisor is 2.
With our Rock fall math game you will be practicing the topic "Order of operations: missing divisor" from 5th grade / Multiply + Divide / Order of operations. The math in this game consists of 16 questions that ask you to work back from the answers to find the missing divisors for each of these 2 step operations.
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.

There are rocks falling from an unstable cliff. You need to break the rocks by clicking / tapping on them...
