Maths

LI: To multiply by 10, 100 and 1000.

 

When we multiply or divide a number by 10, 100 or 1000 (powers of 10) we the digits move either left or right along the place value grid.

 

Example:

If we multiply 521 by 10. All of the digits move 1 place value column to the left. Then we add a place holder (zero) in the units. This makes 5210.

 

When we multiply by 100 we move 2 place value columns to the left and 1000 we move 3 etc.

 

Complete your worksheet.

 

LI: To divide by 10, 100 and 1000.

 

Similarly to multiplying by a power of 10, when we divide by a power of 10 the digits move to the right.

 

Example:

If we divide 5210 by 10 we move the digits to the right by 1 place value column. This makes 521. You may think it should show 521.0 but we don't need that zero as it does not represent a value in this number.

 

Now complete your worksheet!

 

LI: To compare and order number to one million

 

Let's see if 43567 is greater than ( > ) 43576.

 

We start by comparing the largest place value column. Here we have tens of thousands. They both have 4. As they are not different we move to the thousands. There are 3 thousands (no difference). They both have 5 hundreds. However, they have different values in the tens column. The  number on the right is larger - we don't need to bother looking at the ones column.

 

Have a go at your worksheet!

 

LI: To use the column method to subtract more than 4 digits.

 

In class we have had a lot of practise on this. 

Tips:

  • Make sure each subtraction step is done correctly before you move on to the next place value column.
  • Exchange where you need to.
  • Read the word questions carefully. How much further is asking you to find the difference.

 

Complete your worksheet.

 

LI: To solve problems involving addition and subtraction.

 

Have a go at your worksheet. Remember words such as 'sum' are hinting that your need to add and words like 'difference' are asking you to subtract.
