Place Value

What is Place Value?

Place value is when you partition numbers and group them. It is also called the positional notion.

If we had the digit 1, it would go into the ones column. If we took 5,346, the digit 5 would go into the thousands column, 3 would into the hundreds column, 4 goes into the tens column and the 6 goes into the ones column. We can also have decimals in place value charts. In tests, you could get 35 tens, 10 tens is 100 so 3 tens would be 300.

Place value comes in handy with many subjects in maths like rounding, column addition/ subtraction and multiplying by 10, 100, 1,000.

Multiplying by 10, 100, 1,000

When multiplying by 10, 100, 1,000, remember to not just add zeros on the end because if you divide a number like 2,364 by 10, 100, 1,000, you can’t simply take off digits, you move the value too the right (making the number smaller).

Column Addition, Subtraction and Multiplication

Place value in column addition is used when aligning the columns. This ensures that we can read and use the operation properly.

What do you think about place value? Can you see how it might be important for the rest of your maths? What other kinds of problems can you solve if you are confident in place value?
