Tens place value in 5 digit numbers
Each digit in a number has a specific place name and value depending on its position. In our base-10 numeral system, the place values are units, tens, hundreds, thousands, and so on. We read these place values of a number from right to left, starting with the units.
For example, consider the 5 digit number 48,925
- The units position is occupied by the number 5
- The tens position is occupied by the number 2
- The hundreds position is occupied by the number 9
- The thousands position is occupied by the number 8
- The ten-thousands position is occupied by the number 4
To locate the tens digit of a 5 digit number, first find the units place by looking at the last digit on the right. The tens digit is the next digit to the left. In our example above, the tens place is occupied by the number 2.
To get the value of the tens digit, simply multiply that digit by 10. In our example above, the value of the tens digit of 48,925 is:
48,925 : value of tens digit : 2 x 10 = 20.
Here are some more examples of how to get the tens place value of 5 digit numbers:
The value of the tens digit of 97,372 is 70
The value of the tens digit of 81,043 is 40
The value of the tens digit of 28,407 is 0
This topic asks you to work out the value of the tens digit in a series of 5 digit numbers.

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.
