Place Value and Decimal



LI: to shift between place values by multiplication
We learned more about Place Value. Place Value is a value of each digit in a number. For example you have to understand that 2346 is made up of 2000, 300, 40, and 6. Not just 2, 3, 4, and 6. We learned by using materials like sticks, and we grouped them in tens and hundreds.

When you x10 the place value shifts to the left once, and if you multiply it by 100 it will do the same thing except twice. It is also the same with x1000 except you shift it to the left three times. Division is similar with multiplication except you shift it to the right which makes it smaller. If it is divided by 10 it will shift to right once, and so on.

  1. Hi Chris. Good work getting this done quickly. However you haven't explained what happens when you multiply or divide by 10, 100, and 1000. The formatting you used on the spreadsheet also has not shown the numbers very well. Remember that numbers should be in their place value positions, so that all numbers listed below each other should line up with their Ones in the same column, their Tens in the column to the left, and so on. For example, your 500, 8700, and 45 600 do not line up. Please make the appropriate changes to your blog post and make sure the others know about these points as well.
