This chart helps students understand that each place has a value and a place value position. It also shows students that each place in a number has a decimal value and a fraction value. i have included a complete chart with a chart that students fill-in with hints throughout the chart. It is a great help when changing expanded form decimals to standard form. It also helps with common core expanded form using decimals.
