What’s so good about place value charts?

• They’re another way to think about place value and expanded form.

• They help keep our hundreds, tens and ones organized.

• We can use them for addition and subtraction. • They work for bigger numbers than base 10

blocks• They are great for problems that need re-

grouping.
