Mental calculations: 3 digit numbers plus hundreds
Learn how to add multiples of one hundred to 3 digit numbers
When we want to add a smaller number to a bigger number, there are sometimes shortcuts that make it easier. If one of the numbers is 100 or a multiple of 100, adding that number to another number just means increasing the hundreds column of the other number by the number of hundreds you are adding.
So, for instance, if you want to add:
657 + 200
all you need to do is add 2 to the hundreds column value which is 6, so you get 8 for the hundreds column. The rest of the other number stays the same, so the total addition looks like this:
657 + 200 = 857
In the same way, adding 419 and 400 gives:
419 + 400 = 819
It is the same idea if you want to add units to 3 digit numbers but this time you would add to the units column value by the number of units you want to add, so, for instance, 271 + 5 = 276 because all we had to do was add 5 to the units column value to get an answer.
With our Four in a row math game you will be practicing the topic "3-digit number plus multiple of 100" from 2nd grade / Addition / Mental calculations. The math in this game consists of 16 questions that ask you to use mental calculations to add the given multiple of 100 to a three-digit number.

Sometimes in math the most useful skill you can have is to be able to do complicated sums in your head, but don't worry, it's not magic, there's are techniques you can learn.
When we want to add a smaller number to a bigger number, there are sometimes shortcuts that make it easier. If the smaller number is 10 or a multiple of 10, adding that number to a bigger number just means increasing the tens column of the bigger number by the number of tens you are adding.
So, for instance, if you want to add:
30 + 248
all you need to do is add 3 to the tens column value which is 4, so you get 7 for the tens column. The rest of the big number stays the same, so the total addition looks like this:
30 + 248 = 278
It is the same idea if you want to add hundreds but this time you would add to the hundreds column value by the number of hundreds you want to add. Adding units is often just going to affect the units column, so for instance, 271 + 5 = 276 because all we had to do was add 5 to the units column value to get an answer.
The game will reinforce the math you have chosen to learn by getting you to match the question to the correct answer.
